Chapter 1 — Foundations of Restoration

1.1 Philosophy: Restoration vs Refurbishment vs Conservation

Conservation

The stabilisation of an object in its current state — preventing further deterioration without altering appearance or structure. Conservators work in museums and on pieces of significant historical value. Interventions are minimal and fully reversible. A conservator might consolidate flaking veneer with reversible adhesive but would never strip and refinish the surface.

Restoration

Returning an object to a specific point in its history, typically its original or best-known condition. A restorer may replace missing elements, re-glue joints, and refinish surfaces, but does so with respect for original materials and methods. The goal is sympathetic repair that honours the maker's intent.

Refurbishment

Functional renewal without concern for historical authenticity. Stripping a Victorian washstand, painting it grey, and adding modern handles is refurbishment. There is nothing wrong with this for pieces of low historical value, but it is not restoration.

Guiding Principles

  • Always assess before acting
  • Prefer reversible interventions where possible
  • Document condition before work begins — photograph extensively
  • Retain original material wherever structurally sound
  • Match original methods and materials when replacing components
  • Accept that age and honest wear add character — do not chase perfection

1.2 Assessing Value: When to Restore, When to Leave

Before beginning any work, answer these questions:

  1. Is the piece antique? Items over 100 years old generally qualify. Pieces 50–100 years old are "vintage."
  2. Who made it? Signed, stamped, or labelled pieces by known makers carry premium value. Check drawer bottoms, back panels, and inside legs for marks.
  3. Is it structurally sound? A piece that functions safely may need only cleaning and waxing.
  4. What is the provenance? Family history or documented ownership adds value.
  5. What is the market value? Research comparable sales. Over-restoring a common piece wastes time and money.

When to Leave Original Finish Intact

  • The piece retains its original surface in stable condition
  • Patina and wear are consistent and attractive
  • The piece is by a known maker — stripping destroys value
  • Shellac or lacquer is crazed but not flaking — this can often be revived without stripping

When Restoration is Appropriate

  • Structural failure: loose joints, broken components
  • Previous poor repairs that compromise integrity
  • Finish beyond revival: heavy water damage, paint over original finish
  • Upholstery collapsed, stained, or infested
  • Hardware missing or non-functional
⚠ WARNINGStripping original finish from antique furniture almost always reduces market value. A genuine 200-year-old patina cannot be replicated. When in doubt, consult a specialist before proceeding.

1.3 Identifying Furniture Styles and Periods

A working knowledge of period styles helps you date pieces, choose appropriate materials, and set client expectations.

PeriodDatesKey Characteristics

William & Mary1690–1720Walnut, marquetry, cabriole legs emerge
Queen Anne1700–1760Refined cabriole legs, pad feet, walnut/mahogany
Georgian1720–1800Mahogany dominant, Chippendale/Hepplewhite/Sheraton styles
Regency1800–1830Rosewood, brass inlay, sabre legs, Greek/Egyptian motifs
Victorian1837–1901Eclectic revival styles, heavy carving, dark finishes
Edwardian1901–1910Lighter, Sheraton revival, inlaid satinwood
Art Deco1920–1940Geometric forms, exotic veneers, chrome, lacquer
Mid-Century Modern1945–1970Teak, clean lines, organic forms, minimal ornamentation
Arts & Crafts1880–1920Quarter-sawn oak, visible joinery, Stickley/Mission

1.5 Fabric and Stuffing Materials Across Eras

MaterialEraCharacteristics
Dried grasses, strawPre-1700sCheap, compresses quickly, prone to infestation
Horsehair (curled)1700s–presentResilient, long-lasting, expensive. The gold standard.
Hog hair1800s–presentCoarser than horsehair, used as secondary stuffing
Cotton waste / flock1800s–1950sSofter than hair, compresses over time
Coir (coconut fibre)1850s–presentFirm, used in seat pads; rubberised coir in mid-century
Rubberised hair1930s–presentHorsehair bonded with latex, sold in sheet form
Polyester wadding1960s–presentLightweight, hypoallergenic, wraps over foam
Polyurethane foam1960s–presentVarious densities, replaced traditional materials in mass production

1.6 Common Metals Used in Furniture Hardware

Chrome (plating)Mirror-bright blue-white, non-magnetic20th century tubular furniture, hardware
Quick magnetic test: A magnet identifies ferrous metals (iron, steel). Non-magnetic metals require further testing — weight, colour, and acid testing distinguish brass from bronze from copper.

1.7 Safety Principles and Workshop Setup

⚠ WARNINGRestoration work involves hazardous materials including solvents, acids, heavy metals, fine dusts, and sharp tools. Take safety seriously at all times.

PPE

  • Respiratory: P2/N95 for sanding; half-face respirator with OV cartridges for solvent work; full-face for electroplating
  • Eyes: Safety glasses general; chemical goggles for stripping; face shield for grinding
  • Hands: Nitrile gloves for chemicals; leather for metalwork
  • Hearing: Ear defenders when using power tools

Fire Safety

  • Solvent-soaked rags self-combust — place in sealed metal container with water, or spread flat outdoors to dry
  • Keep CO2 or dry powder extinguisher within reach at all times
  • Store solvents and flammable finishes in a metal cabinet away from heat sources

Workshop Layout

  • Separate wet area (stripping, plating) from dry area (woodwork, finishing)
  • Dust extraction on all power tools
  • Daylight-balanced task lighting: 5000K, minimum 500 lux at bench
  • Labelled containers; chemicals stored below eye level; COSHH data sheets accessible

Chapter 3 — Upholstery Restoration

3.1 Stripping Old Upholstery Safely

Before beginning: photograph from all angles, label each removed piece with masking tape noting its position, keep old fabric as templates, and wear a dust mask.

Stripping Procedure — Work Bottom Up

  1. Turn piece upside down on padded trestles. Remove dust cover (cambric) first.
  2. Remove outside back, outside arms, then turn right-side up.
  3. Remove seat cover, inside back cover, inside arm covers in that order.
  4. Remove piping, gimp, and braid trim. Note attachment method.
  5. Remove top stuffing, calico under-cover, secondary stuffing, primary stuffing.
  6. Remove hessian over springs. Note the spring tying pattern before cutting ties.
  7. Remove springs from webbing, then remove webbing, noting pattern and spacing.
  8. Inspect the frame thoroughly.
⚠ WARNINGPre-1970 upholstery may contain materials treated with now-banned chemicals. Work outdoors or in a well-ventilated area. Bag and dispose of old materials promptly.
Original horsehair in good condition can be washed, carded, and reused. Soak in warm soapy water, rinse thoroughly, spread flat to dry, then tease apart.

3.2 Webbing Types and Installation

TypeWidthMaterialUse
Black and white (English)50mmJute/cotton blendTraditional seats and backs — standard choice
Brown jute50mmJuteBudget option, less durable than B&W
Pirelli/Elasticated50mmRubber/elasticMid-century designs, platform seats
Polypropylene50mmSyntheticNot recommended — stretches under load

Installing Jute Webbing

  1. Fold 25mm of webbing over and tack with 5 tacks in a W pattern (3 front, 2 behind staggered) using 16mm improved tacks.
  2. Thread through a bat-type stretcher and lever down to tension. Should depress 10–15mm under firm thumb pressure — not guitar-string tight.
  3. Drive 3 tacks on the opposite rail, cut 25mm beyond, fold excess and drive 2 more tacks staggered.
  4. Leave approximately one webbing-width gap between strands. Weave cross strands alternating the pattern on each.
Typical dining chair seat: 3x3 strands. Armchair seat: 4x4 or 5x5. Back webbing is applied at lighter tension — backs need more give than seats.

3.3 Springs: Types, Tying Methods, and Replacement

TypeDescriptionUse
Double-cone (hourglass)Narrow in the middle, wide at top and bottomTraditional seats, deep cushioning
Barrel springsStraight-sided coilsFirmer seats, backs
Sinuous / zig-zagContinuous wire bent in zig-zagModern/mid-century seats and backs
Pocket coilIndividual springs in fabric pocketsCushion interiors

Eight-Way Hand-Tie Method

The gold standard. Each spring is tied in four directions: front-to-back, side-to-side, and both diagonals.

  1. Drive 16mm tacks halfway into the top of the rail above each row of springs.
  2. Cut laid cord to 1.5x the distance across springs plus 300mm extra. Loop one end around first pair of tacks with a slip knot. Drive tacks home.
  3. Compress the first edge spring to desired height. Tie to the second coil from the top with a clove hitch, then tie the top coil.
  4. Move to the centre top coil and tie — this is the highest point of the spring.
  5. Continue to the far side, then move to the next spring. Repeat at near-side, centre, and far-side top coils.
  6. On the last edge spring, also tie to the second coil from the top before anchoring to the far rail.
  7. Repeat in all four directions. Edge springs should be angled slightly inward.
⚠ WARNINGAlways use laid cord (spring twine) for tying — never string or rope, which stretches under load.

3.4 Stuffing Materials

MaterialUseNotes
Horsehair (curled)First and second stuffingThe professional standard. Tease apart thoroughly before use.
Coir fibreBase layer or budget first stuffingLess resilient than horsehair. Rubberised coir useful for quick pad work.
Cotton felt / battingFinal wrapping layer under coverApply smoothly with no wrinkles or bunches.
Polyester wadding (4oz)Wraps over foam or stuffingTear to shape — cut edges show ridges through fabric.
CMHR foam, seat gradeSeat cushions and padsMinimum 35 kg/m³ density, firm. Required by UK fire regulations.
CMHR foam, back gradeBack cushions25–30 kg/m³, medium or soft grade.
⚠ WARNINGAlways use fire-retardant compliant foam and interliner where required. In the UK, the Furniture and Furnishings (Fire Safety) Regulations 1988 apply to all upholstered furniture made for domestic use.

3.5 Pattern Cutting and Fabric Calculation

  • Measure each panel at its widest and longest points. Add 50mm to each edge for pull-through (75mm for complex shapes).
  • Panels to measure: Inside Back, Outside Back, Seat, Inside Arms (x2), Outside Arms (x2), Front Arm Panels (x2), Front Border, Cushion Top, Cushion Bottom, Cushion Boxing, Piping (linear metres)
  • Standard fabric width: 137cm (54 inches). For plain fabric: total panel heights plus 10% waste. For patterned: add one full pattern repeat per panel, plus 15–20% waste.
  • Typical wing chair: 6–7 metres. Chesterfield sofa: 12–16 metres.

3.6 Edge Rolls, Piping, Tufting, and Pleating

Edge Rolls

Pre-made edge roll: Compressed fibre in hessian, 10–40mm diameter. Tack through the flange at 25mm intervals. Stitched edge: the most durable method — build stuffing over the edge, cover with scrim, and stitch a firm edge using a regulator and double-pointed needle. Create blind stitches first, then top stitches to form the defined roll.

Piping / Welt Cord

  1. Cut bias strips at 45° to selvedge, wide enough to wrap around cord plus two 15mm seam allowances (typically 40–50mm).
  2. Join bias strips with diagonal seams. Wrap around piping cord (standard: 3/16" or 4mm), face outward.
  3. Stitch close to cord with a piping foot. Sew into seams between panels or tack along edges.

Deep Buttoning

  1. Plan a diamond grid: 100–150mm between buttons. Mark positions on foam and cover fabric.
  2. Add 50mm extra fabric per fold between buttons.
  3. Thread a buttoning needle with twine, pass through back, stuffing, and fabric at the button position. Loop through button shank and return, tying off on the back.
  4. Create uniform downward pleats using a regulator needle. Tension all buttons evenly.

3.7 Reattaching Trim and Decorative Tacks

Trim TypeAttachment Method
Gimp braidGimp pins or hot-melt adhesive (pins every 50mm)
Close nailingIndividual nails at 10–15mm spacing
Stud strip (continuous)First and last studs nailed, strip follows between
FringeSewn or tacked through header tape

When applying close nails: mark a guide line, start at the most visible point, use a spacing card jig, and tap each nail gently — decorative heads dent easily. Work outward from the starting point.

3.8 Repairing Frames Before Reupholstery

Loose Joints

  1. Disassemble if possible. Apply steam or hot water to soften old hide glue.
  2. Clean all old adhesive from mortise and tenon surfaces using chisel and hot water.
  3. If the tenon is loose: shim with veneer strips, or drill and pin with a hardwood dowel, or use a fox-wedged tenon for blind mortises.
  4. Re-glue with PVA (Titebond III) or hot hide glue (reversible, traditional). Clamp until fully cured.

Woodworm

  1. Check for active infestation: fresh holes show clean pale wood inside with fine frass below.
  2. Treat with permethrin-based woodworm killer. Allow 48–72 hours to dry fully.
  3. If structural integrity is compromised, the component must be replaced.

IIIWood Restoration

Chapter 4 — Wood Restoration and Repair

4.1 Diagnosing Structural Damage

  1. Rock the piece gently on a flat surface — any movement indicates loose joints or uneven legs.
  2. Grasp each joint and apply gentle racking force. Any movement means the joint has failed.
  3. Check all glue lines with a thin blade (palette knife or feeler gauge).
  4. Inspect for cracks and splits along the grain — check end grain especially.
  5. Examine under raking light to reveal surface damage, dents, and finish failure.
  6. Check for woodworm: 1–2mm round exit holes; fresh frass below indicates active infestation.
  7. Check for water damage: staining, white bloom on finish, warping, delaminating veneer.
  8. Inspect drawers for worn runners, broken guides, split fronts.
  9. Turn the piece over and inspect underneath for previous repairs and concealed damage.
General rule: structural repairs first, then surface work.

4.2 Joint Repair and Reinforcement

Adhesive Selection

AdhesiveOpen TimeReversibilityBest Use
Hot hide glue30–60 secFully reversibleAntique restoration — the correct choice
Liquid hide glue (Titebond)10–15 minPartially reversibleWhen hot hide glue is impractical
PVA (Titebond II/III)5–10 minDifficultGeneral furniture repair
Epoxy (slow-set)30–90 minNot reversibleStructural repairs, gap-filling
Polyurethane (Gorilla)15–20 minNot reversibleOutdoor furniture, difficult joints

Clamping Procedure

  1. Dry-fit the entire assembly before applying glue to verify fit and prepare clamps.
  2. Apply glue to both surfaces of each joint.
  3. Assemble quickly and apply clamps. Check for square: measure diagonally — both diagonals should be equal.
  4. Wipe away squeeze-out with a damp cloth (PVA) or pare with a chisel when gelled (hide glue, epoxy).
  5. Allow full cure: PVA 24 hours, hide glue 24 hours, epoxy per manufacturer.

4.3 Veneer Repair and Replacement

Lifting / Bubbled Veneer

  1. Slit the blister along the grain with a sharp craft knife.
  2. Work thin adhesive under the veneer using a palette knife or syringe.
  3. Press down firmly and clamp using a caul with waxed paper between caul and veneer.
  4. Clamp or weight for 24 hours. Clean squeeze-out.

Missing Veneer Patches

  1. Source matching veneer. Old veneer from reclaimed furniture is ideal — correct thickness and aged colour.
  2. Lay new veneer over the damaged area with grain matched. Cut through both layers simultaneously with a sharp knife following the grain.
  3. Remove damaged veneer within the cut line, clean substrate, glue new patch under a caul.
  4. When cured, level with a cabinet scraper from the centre outward. Finish to match.

4.4 Filling Cracks and Splits

Structural splits: work PVA or hide glue in with a thin blade, close with clamps and cauls, applying pressure perpendicular to the split. A properly glued long-grain split is stronger than the surrounding wood.

FillerCharacteristicsUse
Beeswax sticksSoft, easily applied and colouredSmall dents, nail holes — under wax finish only
Shellac sticks (burn-in)Hard, polishable, precise colour matchUnder lacquer, shellac, or varnish finishes
Epoxy filler (2-part)Hard, sandable, permanent, gap-fillingLarge repairs, structural, outdoor
Sawdust + PVAMatches wood colour reasonablySmall defects; takes stain poorly
Water-based wood fillerSandable, takes stain moderatelyQuick repairs, moderate visibility

4.5 Removing Old Finishes

TestShellacNitrocellulose LacquerPolyurethaneOil/Wax
Methylated spirits on clothDissolves immediatelyMay partially dissolveNo effectNo effect
Acetone on clothDissolvesDissolvesNo effect or slight softeningNo effect
Fingernail scratchMay dentHard, may chipHard, resistantNo film present

Stripping Methods

  • Methylated spirits: Dissolves shellac. Apply with cloth or 0000 wire wool. Gentle and controllable — the preferred method for shellac-finished antiques.
  • Acetone / lacquer thinner: Dissolves nitrocellulose lacquer. Work quickly — high evaporation.
  • NMP/DBE-based strippers (Peel Away, Citristrip): Slower acting but less toxic. Good for delicate surfaces.
  • Methylene chloride-based strippers: Most aggressive. Apply thickly, cover with cling film. Leave 15–60 minutes, scrape off.
⚠ WARNINGPre-1960 paint may contain lead. Test with a lead detection kit before heat stripping or sanding. Never use caustic soda on fine furniture — destroys patina and darkens timber.

4.6 Sanding Techniques

GritGradePurpose
60–80CoarseAggressive stock removal, shaping. Rarely used on furniture.
100–120MediumLevelling surfaces after stripping, removing deep scratches
150Medium-fineGeneral smoothing

220FinePre-finish preparation — standard final grit for most finishes
320Very fineBetween coats (de-nibbing)
400+Ultra finePolishing between coats, wet sanding finishes

Critical Rules

  • Always sand with the grain — cross-grain scratches are permanent
  • Never skip more than one grit grade
  • Sand the entire surface at each grit — spot sanding creates uneven scratch patterns
  • Use a sanding block on flat surfaces
  • Wipe with a tack cloth between grits
  • Raise the grain before water-based finishes — wipe with a damp cloth, dry, then sand lightly with final grit

4.7 Stains and Dyes

Blotch riskLow to moderateHigh on softwoods
To control blotch on pine, cherry, maple: apply a pre-stain conditioner or 1 lb cut shellac before staining. Alternatively, use gel stain — the most forgiving option for blotch-prone woods.

4.8 French Polishing Step-by-Step

French polishing produces the finest hand-applied finish — a deep, lustrous, transparent coating. It is the correct finish for high-quality antique furniture.

Materials

  • Shellac flakes: blonde (pale woods), garnet (dark), button (warm amber)
  • Methylated spirits (denatured alcohol)
  • Raw linseed oil (lubricant)
  • Cotton skin wadding and white lint-free cotton cloth
  • 0000 steel wool
  • Fine pumice powder (for grain filling)

Step 1 — Sealing (Fadding)

  1. Charge the rubber with thin polish (1 lb cut: 125g shellac per litre of methylated spirits).
  2. Apply thin, straight strokes along the grain. Glide on and off at the edges — never stop the rubber on the surface.
  3. Allow 15–30 minutes to dry. De-nib with 320 grit or 0000 steel wool. Repeat 2–3 coats.

Step 2 — Grain Filling (Bodying In)

  1. Apply a tiny drop of raw linseed oil to the sole of the rubber as lubricant.
  2. Sprinkle fine pumice on the surface. Work in small circular motions to press pumice into the pores.
  3. Continue until pores are filled and the surface shows a uniform sheen. Allow to dry overnight.

Step 3 — Building the Body

  1. Charge rubber with stronger polish (2 lb cut). Work in overlapping figure-of-eight and circular patterns.
  2. Use the minimum linseed oil needed — too much clouds the finish.
  3. Apply 10–15 coats, allowing 15–20 minutes between each. Harden overnight.

Step 4 — Spiriting Off (Critical)

  1. Make a fresh rubber. Charge with methylated spirits only — no shellac, no oil.
  2. Work in very light, straight strokes along the grain. The spirits dissolve the oil film.
  3. Allow each pass to dry before the next. Use the lightest possible touch.
  4. Continue until perfectly clear and bright. Allow to harden at least 48 hours before use.
ProblemCauseSolution
Cloudiness / bloomToo much oil, moisture, or cold conditionsSpirit off more thoroughly. Work in warm, dry conditions.
Rubber marks / tracksRubber too wet or too much pressureReduce polish on rubber. Lighter touch.
Dragging / pullingRubber too dry or surface too tackyRecharge rubber. Wait longer between coats.
PinholesAir trapped in pores, insufficient grain fillingMore pumice work during bodying stage.

4.10 Colour Matching and Blending Repairs

Use a daylight-balanced light source (5000–5500K, CRI 95+). Always check the colour match in the lighting where the piece will live — different light sources render colours differently (metamerism).

  1. Analyse the target: background colour (the stain), grain lines (darker), any toner in the topcoat.
  2. Match background first on a test piece of the same wood species. Build colour gradually — easier to darken than to lighten.
  3. Add grain lines with a fine artist's brush (size 0 or 00) and thinned oil stain or pigmented glaze.
  4. Tone overall with a tinted topcoat if the colour is slightly off.
  5. Match the sheen level of surrounding finish — a perfect colour match looks wrong if the gloss level differs.

Colour Theory for Wood

  • To darken: add raw umber or burnt umber. Never use black alone — it looks dead.
  • To warm: add burnt sienna or Vandyke brown
  • To cool: add raw umber or a touch of black
  • To redden: add burnt sienna or garnet shellac
  • To yellow: add raw sienna or blonde shellac

4.11 Advanced Techniques

Steam Dent Lifting

  1. Place a damp cloth over the dent.
  2. Apply a hot iron (cotton/linen setting) to the cloth over the dent.
  3. The steam forces compressed fibres to swell back. Check after 10–15 seconds; repeat as needed.
  4. Allow to dry completely before sanding or finishing.
Only works if fibres are compressed, not cut. Scratches and gouges that have severed fibres will not respond.

Burn-In Stick Repair

  1. Select a shellac stick matching the lightest background colour.
  2. Heat the burn-in knife until it melts the stick readily but is not smoking.
  3. Melt shellac into the defect, pressing firmly and slightly overfilling.
  4. Level using the flat of the heated knife. When cool, final-level with 400–600 grit on a flat block.
  5. Recreate grain lines with a fine brush and thinned pigment stain.
  6. Seal with aerosol lacquer or a pad of French polish. Match sheen to surroundings.

Patina Preservation

  • Never sand through patina — use the lightest touch with fine grits only
  • For shellac finishes, prefer methylated spirits with 0000 steel wool over full stripping
  • Clean rather than strip when possible — reviving an old shellac finish is always preferable
  • Preserving original surface colour and wear patterns is essential to the character and value of antique furniture

AluminiumBright silverNoVery lightSoft; distinctive lightness

5.2 Rust Removal Methods

Mechanical

  • Wire brushing: Manual for light rust. Wire wheel on angle grinder for heavy. Use brass wire brush on softer metals.
  • Sanding: Start 80-grit emery, progress through 120, 240, 400. Wet-and-dry with WD-40 for finer work.
  • Bead blasting: Professional option for heavy rust. Glass bead gives a finer finish than sand.

Chemical

  • Phosphoric acid (Jenolite, Naval Jelly): Converts rust to iron phosphate. Apply, wait 15–30 minutes, rinse.
  • Citric acid: 50g per litre warm water. Soak 12–24 hours. Mild, safe, effective. Rinse and dry immediately.
  • Evapo-Rust: pH-neutral chelation, safe on most metals, non-toxic. Reusable until exhausted.

Electrolytic Rust Removal

  1. Mix electrolyte: 1 tablespoon washing soda per litre warm water.
  2. Connect the rusted part to the NEGATIVE terminal (cathode) of a 12V battery charger. Submerge.
  3. Connect a sacrificial steel anode to the POSITIVE terminal. Submerge but do NOT let it touch the workpiece. Never use stainless steel as the anode.
  4. Leave 2–24 hours. Rust converts to a black oxide that wipes away.
  5. Rinse, dry immediately, and apply a protective finish.
⚠ WARNINGHydrogen gas is produced at the cathode during electrolysis. Work in a ventilated area with no sparks or flames.

5.3 Polishing Stages and Compounds

5. Colour compoundWhite rouge or Dialux white on loose cotton mopHigh-gloss mirror finish
6. Final polishJeweller's rouge or Autosol on soft clothRemoves compound haze, final brilliance
⚠ WARNINGAlways wear eye protection at the buffing wheel. Hold the workpiece BELOW the centre line — the wheel should spin down toward you. Keep gloves OFF — they can catch in the wheel.

5.4 Recreating Antique Patinas

Brass Darkening

  • Liver of sulphur: Pea-sized lump in warm water. Dip cleaned, degreased brass. Darkens gold → brown → black. Rinse and seal with wax.
  • Ammonia fuming: Place in sealed container with ammonia dish (not submerged). Blue-green patina over hours to days. Seal with lacquer.
  • Salt and vinegar: Equal parts, painted on, sealed container. Green verdigris over 24–48 hours.

Steel / Iron Ageing

  • Vinegar and salt soak: Creates rapid surface rust. Control by timing. Seal with wax or oil.
  • Gun bluing (selenium dioxide): Creates blue-black oxide. Oil to seal.
Always seal artificial patina with lacquer, wax, or Renaissance microcrystalline wax or it will continue to develop and may rub off.

5.6 Electroplating Step-by-Step (Nickel — Home Scale)

⚠ WARNINGElectroplating involves hazardous chemicals. Full PPE required: chemical goggles, nitrile gloves, acid-resistant apron, acid gas respirator. Local exhaust ventilation over all tanks at all times.

Watts Nickel Bath

ChemicalPer LitrePurpose
Nickel sulphate250gPrimary nickel source
Nickel chloride45gImproves anode corrosion and conductivity
Boric acid35gpH buffer
Wetting agent (sodium lauryl sulphate)0.5mlPrevents pitting from hydrogen bubbles
Target pH: 3.5–4.5. Mix in distilled or deionised water. Heat to dissolve. Filter before use.

Surface Preparation (Critical)

  1. Strip old plating if present using reverse electrolysis.
  2. Polish base metal to desired finish — every scratch visible in base metal will appear in the plating.
  3. Degrease in ultrasonic cleaner with alkaline solution at 60°C for 5–10 minutes. Surface should sheet water uniformly — if it beads, degrease again.
  4. Acid activate: dip in 10% hydrochloric acid for 30–60 seconds. Quick-rinse in distilled water and transfer immediately to plating tank. Part must not dry.

Plating Procedure

  1. Suspend part in plating solution using copper wire jig. Connect to NEGATIVE terminal (cathode).
  2. Connect nickel anode bars to POSITIVE terminal. Anodes should flank the part evenly.
  3. Set current density: 2–5 A/dm². Plating rate: ~0.025mm per hour at 3 A/dm².
  4. Maintain temperature at 50°C ±5°C. Agitate gently throughout.
  5. Remove when desired thickness is reached (decorative hardware: 10–20 microns, 25–50 minutes). Rinse twice in clean water. Dry with clean cloth or compressed air.

Chapter 6 — Leather Restoration

6.1 Cleaning Methods

Leather Type Identification

  • Aniline: Dyed through, no surface coating. Very absorbent — water drop darkens and absorbs within seconds.
  • Semi-aniline: Light protective coating. Water beads momentarily then absorbs.
  • Pigmented (protected): Heavy surface coating. Water sits on surface.

Cleaning Procedure

  1. Vacuum thoroughly with a soft brush attachment. Remove all loose debris from crevices.
  2. Clean with a pH-balanced leather cleaner (pH 4.5–5.5). Apply with soft cloth in gentle circular motions.
  3. Rinse by wiping with a clean damp cloth. Remove all soap residue.
  4. Dry naturally. Never use heat — it dries and cracks leather.

Stubborn Stains

  • Ink: Isopropyl alcohol on a cotton bud, dabbed gently. Test first — may remove colour.
  • Grease: Cornstarch or talcum powder. Leave 12 hours, brush off.
  • Mildew: Equal parts water and isopropyl alcohol. Address root cause (humidity, ventilation).
  • Water marks on aniline: Dampen the entire panel evenly with distilled water. Allow to dry uniformly.

6.2 Rehydrating Leather

  1. Clean first. Apply a leather conditioner containing lanolin, neatsfoot oil, or a proprietary blend (Lexol, Leather Honey, Connolly Hide Care).
  2. Apply sparingly in circular motions. Allow to absorb 30–60 minutes. Buff off any excess.
  3. Repeat every 3–6 months for maintenance. Apply multiple coats on severely dried leather (one coat per day, 3–5 days).
For severely stiff leather: apply pure neatsfoot oil, allow 24 hours, then follow with conditioner. Work the leather gently by hand — flex, stretch, and massage. Over-oiling can darken the colour permanently.

6.3 Crack Repair

Surface Cracks (Finish Only)

  1. Apply leather filler in thin layers with a palette knife. Allow each layer to dry before the next.
  2. Sand smooth with 800–1200 grit wet-and-dry when dry.
  3. Apply leather colourant to match. Seal with leather finish/topcoat in matching sheen.

Deep Cracks

  1. Apply a flexible fabric patch to the back of the crack using flexible adhesive.
  2. Fill from the front with leather filler in thin layers.
  3. Texture the final layer to match surrounding grain using a grain pad pressed into wet filler.
  4. Colour and seal as above.

6.4 Re-Dyeing

Pigmented Leather

  1. Clean thoroughly. Lightly sand with 400–600 grit (dry) to provide a key. Wipe with isopropyl alcohol.
  2. Apply a leather deglazer if the existing coating is thick.
  3. Apply leather colourant in thin coats — 3–6 coats for full coverage, drying between each.
  4. Apply leather finish/sealer in desired sheen.

Aniline Leather

  1. Apply aniline dye with a sponge or wool dauber. Work quickly and evenly.
  2. Multiple coats deepen the colour. You can only go darker with aniline dyes.
  3. Seal with an appropriate aniline leather protector.

6.5 Replacing Panels

  1. Carefully remove the damaged panel. Note how it was attached.
  2. Take a sample of the original to a leather supplier for colour and weight matching. Upholstery leather is typically 1.0–1.4mm.
  3. Cut the new panel using the old panel as a template. Add seam allowance if sewn.
  4. Use a leather needle and heavy-duty thread (polyester or nylon) on an industrial sewing machine for sewn panels.
  5. Condition the new panel and, if needed, age it using a thin wash of diluted dye or antiquing cream.
VDecorative Techniques

Chapter 7 — Surface Finishes and Decorative Techniques

7.1 Gilding

MethodDescriptionUse
Water gildingGold leaf on gesso and bole ground. Can be burnished to a mirror finish.High-quality frames, mirrors, furniture mounts
Oil gilding (mordant)Gold leaf over oil-based size. Cannot be burnished. Simpler.Furniture, architectural details, sign-writing
Transfer gildingGold leaf attached to tissue for easier handling.Oil gilding on complex surfaces
Powder / wax gildingMetallic powder in wax medium. Cheaper effect.Touch-ups and small details

Oil Gilding Procedure

  1. Prepare the surface: smooth and sealed. Apply yellow ochre or red oxide paint as a base coat.
  2. Apply oil size thinly and evenly. Brush carefully for even coverage.
  3. Wait for the tack: touch with a clean knuckle — tacky but not transferring. If you leave a fingerprint, it's too wet. If not tacky, you've missed the window and must recoat.
  4. Apply transfer gold: press tissue-backed leaf onto the sized surface, rub gently through the tissue, peel away.
  5. Overlap each sheet by 2–3mm. Work systematically.
  6. Press gold into crevices with a soft gilder's mop brush. Remove excess (skewings) and press into any missed spots.
  7. Seal with clear shellac or lacquer. For antique look, apply a tinted glaze or wax over sealed gold.

7.2 Ebonising Wood

Method 1 — India Ink (Simplest)

  1. Sand to 320 grit. Apply India ink (shellac-based, not acrylic). Multiple coats for depth.
  2. Sand lightly between coats with 400 grit. Finish with black wax or shellac.

Method 2 — Iron and Tannin Reaction (Traditional)

  1. Place a pad of fine steel wool in white vinegar, loosely covered. Leave 3–7 days until dark. Strain through a coffee filter.
  2. Optionally apply strong black tea first to boost tannin content. Allow to dry.
  3. Brush the iron acetate solution onto the wood. It reacts with tannins to turn the wood black. Multiple coats deepen colour.
  4. Allow to dry fully (24 hours). Sand lightly with 400 grit. Finish with black wax, shellac, or lacquer.
Close-grained woods (pear, cherry, maple, beech) ebonise best. Open-grained woods (oak, ash) show grain texture through the black — which can be attractive.

7.3 Distressing Techniques

Physical Distressing

  • Denting: Strike with a bag of bolts, a chain, or a rock. Random impacts matching natural wear patterns.
  • Scratching: Drag a nail or wire brush following natural use patterns (more wear on edges, around hardware).
  • Rounding edges: Sand sharp edges with 120-grit on a block.
  • Worn areas: Sand through topcoat on high points selectively — arm fronts, seat edges, around handles.
  • Fly spots: Flick thinned dark stain from a brush to create small dark spots.

Chemical / Colour Distressing

  • Tinted glaze: Burnt umber in glazing medium over the finish. Wipe from high points, leaving colour in crevices.
  • Dark wax (Briwax, Liberon): Applied over a lighter finish, settles in grain and crevices.
  • Ammonia fuming (oak only): Seal the piece in a plastic tent with a dish of strong ammonia. 24–48 hours darkens significantly.
⚠ WARNINGDo not inhale ammonia fumes. Fuming must be done outdoors. Wear a respirator.

7.4 Decal Restoration

  1. Clean gently with a slightly damp cloth. Do not soak. Do not use solvents on decals — they dissolve the printing.
  2. To re-adhere lifting decals: carefully lift the loose edge with a thin blade. Apply PVA or methylcellulose paste under the decal with a fine brush. Press flat, roll with a brayer. Weight flat until dry.
  3. Apply protective clear shellac or lacquer by spray (preferable to brush). Build in multiple thin coats.

7.5 Lacquer Repair

Small Chips and Scratches

  1. Clean with naphtha or white spirit. Apply thin coats of matching lacquer with a fine artist's brush.
  2. Level with 600-grit wet-and-dry when cured. Polish with rubbing compound, then swirl-free polish.

Crazing (Fine Network Cracks)

For nitrocellulose lacquer: spray a fine mist coat of lacquer thinner. The solvent melts the existing finish, which re-flows and heals as it dries. Practice first — over-application dissolves the finish completely.

Clouding / Blushing (White Haze)

Caused by moisture trapped in the finish. Spray a mist of lacquer retarder to allow moisture to escape. Or heat gently with a heat gun on low setting held 300mm away while exposing to moving air.

7.6 Repairing Chipped Enamel

  1. Clean the chip. Remove loose enamel. Treat exposed metal with rust converter if ferrous.
  2. Apply appliance epoxy touch-up paint in a matching colour. Build in thin coats.
  3. Once fully cured (48–72 hours), level with 1000-grit wet-and-dry paper used wet.
  4. Polish with automotive rubbing compound.
Large enamel losses on valuable items should be sent to a professional re-enamelling service. Enamel cannot be re-fired at home.

8.1 Victorian Buttoned-Back Armchair — Full Restoration

Case Study 01c.1880 Mahogany-Framed Armchair with Buttoned Back and Sprung Seat

Diagnosis

  • Upholstery collapsed. Horsehair compressed. Webbing perished. Two of nine seat springs broken.
  • Back left leg joint loose. Small split in right front seat rail.
  • Original French polish with honest wear — intact and worth preserving.
  • Original brass castors, all present, tarnished but functional.
Materials

Timeline
2–3 weeks

Step-by-Step

  1. Document thoroughly. Photograph from all angles, note fabric layout and button count.
  2. Strip upholstery (see §3.1). Save horsehair for washing and reuse. Keep old fabric panels as templates.
  3. Frame repair: disassemble loose back leg joint, clean old hide glue with hot water, re-glue with PVA, clamp 24 hours. Repair the split front rail: inject PVA, clamp, reinforce inside face with a hardwood glue block.
  4. Treat all frame timbers with woodworm treatment as a precaution.
  5. Revive frame finish: clean existing French polish with a rubber dampened with methylated spirits and a trace of linseed oil. Touch up bare areas with garnet shellac. Final spirit-off pass to even the sheen.
  6. Web the seat: 4x4 strands of B&W webbing, interwoven. Web the back: 3x3 strands at lighter tension.
  7. Spring the seat: 9 springs in a 3x3 grid, stitched to webbing at 4 points each. Lash with laid cord in 8 directions.
  8. Cover springs with 12oz hessian tacked to inner edge of rails.
  9. Stitch bridle ties. Apply first horsehair stuffing, building a firm, slightly domed profile.
  10. Cover stuffing with scrim, adjust with regulator, then edge-stitch the seat front (2 rows blind, 1 row top stitches).
  11. Apply second stuffing, calico under-cover, and cotton felt layer. Adjust until the calico stage is perfect.
  12. Button the inside back: mark positions, create downward pleats, thread each button through with a buttoning needle, tie off on the outside back.
  13. Apply seat cover, piping, inside/outside arm covers, and outside back. Use back-tacking strip for clean lines.
  14. Apply gimp braid with gimp pins at 40mm intervals. Apply cambric dust cover.
  15. Clean and polish castors with tripoli and white rouge. Wax with Renaissance wax.

Common Mistakes

  • Under-tensioning webbing — leads to premature sagging
  • Uneven stuffing — lumps show through the cover
  • Inconsistent button depth — very visible and unprofessional
  • Not protecting show-wood with masking tape during upholstery

8.2 Mid-Century Teak Dining Chair — Structural Repair and Refinish

Case Study 02c.1960 Danish Teak Dining Chair (Farstrup Style) — Drop-In Seat Pad

Diagnosis

  • All four leg-to-rail joints loose. Front left leg has a crack originating from the joint.
  • Finish dull and water-marked. Several scratches across the seat frame.
  • Seat pad vinyl cracked and split. Foam collapsed.

Timeline
6–8 hours

Step-by-Step

  1. Remove drop-in seat pad. Set aside.
  2. Disassemble the chair. Use a rubber mallet to tap joints apart. If PVA-glued, inject white vinegar or hot water and wait.
  3. Clean all joints with a chisel and hot water. Remove all old adhesive to bare wood.
  4. Repair cracked front left leg: work PVA into the crack with a palette knife, clamp with F-clamps and cauls. Consider drilling and pinning with a 6mm dowel if the crack originates from the mortise.
  5. Reassemble all joints simultaneously with PVA. Apply band clamp around the whole chair. Check for square. Cure 24 hours.
  6. Refinish: scrape old finish with a cabinet scraper. Sand through 180, 240, 320 grit. Apply teak oil — flood, wait 15 minutes, wipe off all excess. Second coat after 24 hours. Buff lightly with 0000 steel wool.
  7. Re-pad the drop-in seat: cut new CMHR foam 10mm oversize on each side. Wrap in polyester wadding (tear, don't cut). Lay cover fabric, pull taut, staple from centre of each side outward. Fold corners neatly. Staple cambric to cover raw edges.
  8. Refit seat pad.

Common Mistakes

  • Regluing without cleaning old adhesive — PVA does not bond to cured PVA
  • Over-sanding teak — oily surface clogs paper; use fresh paper frequently
  • Not wiping off all oil — creates a sticky, dust-attracting film
  • Cutting foam undersize — seat will feel hollow at the edges

8.3 Water-Damaged Oak Dining Table

Case Study 03c.1930 Solid Oak Extending Dining Table — Water Stain and Mechanism Repair

Diagnosis

  • Vase of flowers left for weeks caused a large oval water stain (approx. 300x200mm). Shellac finish white-bloomed; wood beneath darkened.
  • One extending leaf runner seized. Two bolt fixings for the extending mechanism stripped.
  • Original dark shellac finish elsewhere intact with attractive patina.
Materials

Total (pro)
~£416
Timeline
8–12 hours

Step-by-Step

  1. First attempt: apply a rubber of methylated spirits with a trace of linseed oil to the damaged area, working with the grain. This often resolves white bloom within the finish.
  2. If bloom remains: strip shellac from the damaged area only with methylated spirits and 0000 steel wool. Feather the edge into the surrounding intact finish.
  3. If wood beneath is darkened: apply oxalic acid solution (25g in 250ml warm water). Brush onto the stain, allow to dry, repeat if needed. Neutralise with borax solution (15g per 250ml water). Allow to dry fully.
  4. Colour match: apply dilute stain (burnt umber in shellac medium) to the bleached area, building colour to match surrounding wood slowly under daylight. Seal with thin shellac coat.
  5. Rebuild French polish over the repair using button shellac. Blend into surrounding finish by working the rubber slightly beyond the repair boundary. Spirit off. Allow to harden 48 hours.
  6. Wax the entire table top with beeswax polish to unify old and new finish.
  7. Free seized runner: apply penetrating oil, tap gently. Clean channel of old wax. Apply candle wax to runners.
  8. Repair stripped bolt holes: drill out to 10mm, glue in 10mm hardwood dowels with PVA, cure 24 hours, re-drill pilot holes, refit bolts.

Common Mistakes

  • Too strong a bleach solution — can lighten the wood far beyond surrounding tone
  • Stripping too large an area — work the minimum area necessary
  • Rushing French polish build-up — thin coats properly dried are invisible
  • Not neutralising oxalic acid — residual acid attacks the new finish

8.4 Rusted Brass Hardware Restoration

Case Study 04Set of 8 Brass Drawer Handles (Swan-Neck Bail Type, c.1780 Style)

Diagnosis

  • Heavy tarnish and green verdigris. Two handles with bent bails. Three backplates lacquered — lacquer peeling.
  • One handle is a later replacement with slightly different casting detail.

Timeline
3–4 hours

Step-by-Step

  1. Remove all handles. Label each with its drawer position.
  2. Remove old lacquer: soak lacquered handles in acetone for 15 minutes. Wipe off softened lacquer.
  3. Remove verdigris: soak all handles in citric acid solution (50g per litre warm water) for 1–2 hours. The verdigris dissolves and brass brightens.
  4. Rinse thoroughly. Dry immediately — water spots are difficult to polish out.
  5. Straighten bent bails: grip in a vice with soft jaws, bend gently back with pliers. Work slowly — brass work-hardens. Anneal with a torch (heat to dull red, quench) if needed before bending.
  6. Polish: emery cloth 400 grit → 1000 grit → tripoli on stitched cotton mop → white rouge on loose cotton mop → Brasso or Autosol by hand.
  7. Apply Renaissance microcrystalline wax. Buff to a sheen. Museum-grade protection — prevents tarnishing for months to years.
  8. Address the replacement handle: source a better match from architectural salvage, or move to the least visible drawer position.

Common Mistakes

  • Over-polishing — removes casting detail by aggressive buffing
  • Using steel wool on brass — steel particles embed and rust, creating dark spots
  • Not drying immediately after rinsing — water spots are hard to remove
  • Applying lacquer to furniture brass — wax is always preferable

8.5 Leather Club Chair Refurbishment

Case Study 05c.1940 Leather Club Chair — Coil-Sprung Seat, Aniline Hide

Diagnosis

  • Original dark brown aniline hide. Seat panels dry and cracked. Inside arm leather worn through at front edges. Back and outside panels sun-faded on one side.
  • Springs and webbing intact. Frame joints tight.
  • Decision: Replace seat and inside arm panels. Restore back panels (clean, condition, re-dye).

Timeline
15–20 hours

Step-by-Step

  1. Document and determine which panels to replace versus restore.
  2. Remove panels to be replaced. Use old panels as templates.
  3. Clean all retained leather (§6.1). Condition with lanolin conditioner — 2–3 coats over 3 days.
  4. Fill surface cracks in retained panels with leather filler. Sand smooth when dry.
  5. Re-dye faded panels: apply aniline dye with a sponge over 3–4 coats, blending where faded meets unfaded to avoid a hard line.
  6. Cut new panels using old panels as templates, adding 25mm tacking allowance.
  7. Refresh stuffing: add cotton felt over existing horsehair if compressed. Fit new seat panel, pulling taut and tacking from centre outward. Fold corners neatly.
  8. Fit new inside arm panels to match original attachment method.
  9. Apply decorative studs along visible seams, matching the original pattern and spacing.
  10. Apply leather protector to all surfaces. Apply cambric dust cover. Final condition the entire chair.
  11. Inspect under daylight and under the chair's intended ambient lighting. Adjust dye if needed.

Common Mistakes

  • Using pigmented leather to replace aniline — the texture and depth look completely different
  • Not conditioning retained leather enough — new next to dry old emphasises the difference
  • Stretching leather too tight — it stretches in use and will distort
  • Colour-matching under workshop lighting only — always verify under daylight
VIIReference and Business

Chapter 9 — Troubleshooting Guide

9.1 Loose Joints After Glue-Up

Joint loosens within days of glue-up
Cause Old adhesive not fully removed; PVA applied over cured PVA
Fix Disassemble, clean joint surfaces completely to bare wood, re-glue
Joint holds initially then loosens over months
Cause Insufficient clamping pressure; starved joint (too little glue)
Fix Disassemble, apply adequate glue to both surfaces, clamp firmly
Joint is spongy or rubbery
Cause Polyurethane glue used without adequate moisture; voids created by foaming
Fix Disassemble, clean out foam residue, re-glue with PVA or hide glue
Joint too loose to hold (worn tenon)
Cause Tenon has shrunk or worn, leaving excessive gap
Fix Shim tenon with veneer strips or replace with a loose tenon
Dowel joint fails
Cause Dowel too short, smooth (not fluted), insufficient glue
Fix Replace with longer, fluted dowel; ensure glue reaches bottom of hole
Joint creaks when loaded
Cause Near failure, partial adhesion
Fix Inject thin CA glue or dilute PVA with a syringe; clamp

9.2 Blotchy Stain

Dark splotches on softwood (pine, cherry)
Cause Uneven absorption due to varying grain density
Fix Sand back, apply pre-stain conditioner or 1 lb cut shellac, re-stain
Dark areas around knots
Cause Resin concentration
Fix Seal knots with shellac (knotting solution) before staining
Stain won't penetrate in patches
Cause Residual finish, glue, or silicone contamination
Fix Strip completely. Wipe with naphtha to check — dark spots indicate residue. Remove all contaminants.
End grain much darker than face grain
Cause End grain absorbs more stain
Fix Pre-seal end grain with a thin shellac wash, or stain end grain last and wipe off quickly

9.3 Wrinkled Upholstery

Wrinkles radiating from corners
Cause Fabric not pulled evenly; one side tighter
Fix Remove tacks on wrinkled side; re-pull from centre of each rail outward, tensioning evenly
Diagonal creases across seat or back
Cause Fabric cut off-grain (warp/weft misaligned)
Fix Remove and re-cut, aligning fabric grain with the frame
Wrinkles over stuffing
Cause Lumpy or uneven stuffing beneath
Fix Remove cover, adjust stuffing with regulator, rebuild smooth surface before re-covering
Loose fabric after weeks of use
Cause Insufficient tension; foam compressed
Fix Re-pull and re-tack. Replace foam if significantly compressed.
Prevention: Always pull from the centre of each rail first, working outward. Temporary-tack (halfway) across the entire panel before driving any tacks home.

9.4 Peeling Lacquer

Lacquer peeling in sheets
Cause Applied over contaminated surface (wax, silicone, oil)
Fix Strip completely, clean with naphtha, sand, re-apply
Lifting between coats
Cause Exceeded re-coat window without sanding
Fix Sand between all coats with 320 grit after the re-coat window has passed
Water-based lacquer peeling from oil-based stain
Cause Incompatible chemistry; oil stain not fully cured
Fix Allow oil stain 7+ days to cure. Apply dewaxed shellac barrier coat. Then apply water-based lacquer.

9.5 Plating Flaking

Plating peels from base metal
Cause Inadequate surface preparation; grease or oxide residue
Fix Strip, repeat full preparation: polish, degrease, activate, copper strike on steel, plate
Plating blisters
Cause Hydrogen embrittlement; gas trapped between plating and substrate
Fix Bake steel parts at 190°C for 4 hours before plating to drive off absorbed hydrogen
Plating peels from pot metal (Zamak)
Cause Pot metal outgasses; requires special preparation
Fix Requires cyanide copper bath (professional only). Not suitable for amateur plating.

9.6 Colour Mismatch After Repair

Repair is lighter than surrounding wood
Cause New wood lacks oxidation/age colour
Fix Apply stain or dye to darken gradually, or use a tinted topcoat (toner)
Matches under workshop lights but not daylight
Cause Metamerism — different pigments matching under one light source but not another
Fix Use daylight-balanced lighting (5000K, CRI 95+). Always match in the piece's intended environment.
Grain pattern doesn't match
Cause Repair wood has different grain character
Fix Paint grain lines with artist's brushes and pigmented glaze, matching the pattern of the surrounding wood. Seal with clear topcoat.
Filled area doesn't take stain
Cause Filler material absorbs stain differently or not at all
Fix Use pre-tinted filler matched to the final colour. Or seal the fill and apply colour with a brush and pigmented topcoat.

Chapter 10 — Business Considerations

10.1 Pricing Restoration Jobs

Pricing Models

  • Time and materials: Hourly rate plus material costs with 10–20% markup. Transparent and fair. Best for complex or unpredictable jobs.
  • Fixed quote: Total price for the completed job. Clients prefer this. Best for straightforward, repeatable jobs.
  • Phased pricing: Quote for assessment and stripping as phase 1. Quote for phase 2 after full inspection. Protects you from hidden problems.

Setting Your Hourly Rate

Minimum hourly rate = (Annual overhead + Desired annual income) ÷ Billable hours per year

Example: £8,000 overhead + £30,000 income = £38,000 ÷ 1,440 billable hours = £26.39/hr minimum. Add 15–25% buffer.

Experience LevelTypical Rate (UK)
Entry level / rural£20–30 per hour
Experienced / urban£30–50 per hour
Specialist / high-end£50–80 per hour

Quoting Procedure

  1. Inspect the piece in person. Never quote from photographs — hidden damage is common.
  2. Agree scope of work. Define what is included and excluded.
  3. Written quote: description of work, material specifications, estimated timeline, price inc. VAT if applicable, exclusions, payment terms (50% deposit, balance on completion).
  4. Get written acceptance before ordering materials or beginning work.

10.2 Sourcing Materials Affordably

  • Trade accounts: 20–40% below retail. Most require proof of business.
  • Bulk buying: Webbing, tacks, twine, and consumables are significantly cheaper in quantity.
  • Reclamation yards and salvage: Period-appropriate timber, hardware, and components — often cheaper and more authentic than new.
  • Auction lots: Job lots of tools, fabric remnants, and hardware. Workshop clearances are frequent online.
  • Reuse and reclaim: Wash and reuse horsehair. Save fabric offcuts for piping and samples.

10.3 Working with Clients

  • Show examples of previous work. Set realistic expectations.
  • Explain the difference between restoration and refurbishment — some clients expect a 200-year-old piece to look "new."
  • Under-promise and over-deliver on timelines.
  • Warn about potential hidden issues before work begins.
  • Contact the client immediately if you discover something that changes scope or cost. Never proceed with additional work without approval.
  • Keep a paper trail: written quotes, agreed scope, change approvals, invoices.
  • If a piece is not worth restoring, be honest. Offer a basic repair or refurbishment as an alternative.

10.4 Photographing Work for Portfolio

  1. Before photos: Photograph as-received from multiple angles. Include close-ups of damage. These tell the story.
  2. During photos (optional): Document key stages — stripped frame, springs installed, stuffing, calico stage.
  3. After photos: Same positions as the before shots for direct comparison.
  • Background: Clean and uncluttered — white or grey wall, or plain backdrop cloth.
  • Lighting: Diffused natural daylight is ideal. Position lights at 45 degrees for even illumination. Avoid direct sunlight.
  • Angles: Front, 3/4 view, side, back, top (for tables), and close-ups of details (carving, fabric, hardware, finish quality).
  • Website with before/after galleries by project type, Instagram for consistent high-quality images, physical portfolio book for consultations.

10.5 Insurance and Liability

⚠ NOTEThis section provides general guidance only. Consult a qualified insurance broker for advice specific to your situation and jurisdiction.
Insurance TypeWhat It CoversWhy You Need It
Public liabilityInjury to third parties or damage to their propertyEssential. A client trips over your equipment; delivered piece damages a doorframe.
