Restoration
& Repair

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

1.3 Identifying Furniture Styles and Periods

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

1.7 Safety Principles and Workshop Setup

PPE

• Respiratory: FFP2 or FFP3 disposable mask 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

• Rags soaked in linseed oil, Danish oil or other drying oils can self-combust as they cure: place them in a sealed metal container with water, or spread them 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

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.

3.2 Webbing Types and Installation

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.

3.3 Springs: Types, Tying Methods, and Replacement

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.

3.4 Stuffing Materials

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

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.

3.9 Cost Estimation and Pricing Jobs

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.

4.2 Joint Repair and Reinforcement

Adhesive Selection

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 by measuring 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, with the 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.

4.5 Removing Old Finishes

Finish Identification

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, as it evaporates fast.
• Benzyl alcohol or DBE-based strippers (for example Citristrip, Peel Away): Slower acting but less toxic. Good for delicate surfaces.
• Methylene chloride (dichloromethane) strippers: Most aggressive, but banned from sale to the public in the UK since 2012 and restricted to trained professionals. Do not use them in a home workshop.

4.6 Sanding Techniques

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

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

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.

4.9 Other Finishes

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; it is 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.

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

5.1 Identifying Metals

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.

5.3 Polishing Stages and Compounds

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.

5.5 Replating Overview

How a Plated Finish Is Built Up

A plated finish is rarely a single coat. It is usually a stack of very thin layers, and each layer has a job. The thickness of every layer is measured in microns (µm). One micron is a thousandth of a millimetre, so a human hair is roughly 70 microns across.

• Base metal: The object itself. Brass, copper and EPNS (electroplated nickel silver, the usual base under old silver-plated cutlery and teapots) are the easiest to plate.
• Nickel undercoat: A thin barrier layer. Without it, copper from brass or copper slowly works its way into the silver over months and years, giving a yellow or pink tinge and weakening the bond.
• Silver: The finish you see. It comes out of the tank a soft matt white and is burnished or buffed to a shine.

5.6 Silver Plating Step-by-Step (Home Scale)

What Is Happening in the Tank

Electroplating uses electricity to move metal from one place to another. Bars of pure silver and your item both sit in a liquid that has silver dissolved in it. When you switch the power on, silver leaves the bars, travels through the liquid as tiny charged particles called ions, and settles on your item as a thin, even coat.

• Cathode (negative, −): Your item. This is where the silver lands. A handy way to remember it: the cathode catches.
• Anode (positive, +): The silver bars. They slowly dissolve to replace the silver that leaves the solution.
• Electrolyte: The plating solution. It carries the silver ions and lets current flow.

What You Can Plate

Equipment and Materials

Work Out Your Current

The right current depends on how much surface your item has. Too little current is slow and patchy. Too much gives a dark, brown or powdery coat that rubs off. Silver is much more sensitive to this than nickel. The measure used is current density, in amps per square decimetre (A/dm²). One square decimetre is a square 10 cm by 10 cm, or 100 cm².

1. Estimate the surface area. An easy way for a flat item like a spoon: lay it on 1 cm squared paper, draw round it, and count the squares inside the outline. Double it for the two sides and add 10% for the edges.
2. Convert to square decimetres by dividing square centimetres by 100.
3. Multiply by the current density you want. Check your solution's data sheet. If it gives none, start at 0.5 A/dm².

The Whole Process at a Glance

Step 1 to 5: Preparation (Critical)

Plating copies whatever is underneath it, grease and scratches included. Silver cannot grip a greasy surface, and even a fingerprint can cause a patch to peel later. Do not rush this part.

1. Strip or keep the old plating. If old silver is just worn through at the high points, it can stay. If it is flaking or blistered, remove it with a silver stripping solution from your plating supplier, following its instructions.
2. Polish. Remove tarnish and corrosion, then polish the base metal to the finish you want. Every scratch visible in the base metal will show in the plating, because silver does not fill scratches.
3. Wipe off all polishing compound. It is greasy. From this point on, handle the item only with clean gloves or by its hanging wire.
4. Degrease. Soak the item in a hot alkaline degreasing solution (around 60°C) for 10–15 minutes and scrub it with a soft brush, or use an ultrasonic cleaner for 5–10 minutes.
5. Rinse and do the water-break test (Diagram 5). If the water beads, degrease again.
6. Acid dip. Dip in 10% sulphuric or hydrochloric acid, or the activator your supplier recommends, for 30–60 seconds. This removes the invisible oxide film that stops plating sticking.
7. Rinse in clean water and move on straight away. The item must not dry out between here and the silver tank.

Step 6: Nickel Undercoat (Recommended)

A thin nickel layer under the silver makes the finish last much longer on brass and copper. It is worth doing on anything that will be handled or used, such as cutlery. You can skip it for a first practice piece, or for display items, if your silver solution's data sheet says it plates directly onto brass or copper.

Ready-made nickel solution is the easiest route. If you want to mix your own, the standard recipe is the Watts nickel bath:

1. Hang the item from the negative lead and the nickel anodes from the positive lead, as in Diagram 2.
2. Plate at about 3 A/dm² for 6–10 minutes. That gives roughly 3–5 µm (nickel thickness in µm ≈ 11 × current density × hours).
3. Switch off, lift out and rinse well in two tubs, finishing with distilled water, so no nickel solution gets carried into the silver tank.
4. Move straight to the silver tank. Fresh nickel quickly grows an invisible oxide skin in air. If it dries or waits more than a minute or two, give it a brief acid dip and rinse again.

Step 8: Silver Plating Procedure

1. Check the silver solution: at room temperature (roughly 18–25°C) and at the pH on its data sheet. Make sure the anodes are in place and connected to the positive (red) lead.
2. Set the power supply's current limit to the amps you calculated, with the item not yet connected.
3. Clip the item's hanging wire to the NEGATIVE lead, then lower it into the solution with the power already switched on. This is called live entry. If a clean item sits in silver solution with no current, silver can coat it chemically, and that coat looks fine but peels later.
4. Hang it fully under the surface, 2–3 cm below the top, with its main faces turned towards the anodes, 5–10 cm away.
5. Check the meter reads the current you set. The voltage will usually settle somewhere around 1.5–3 V. If it climbs much higher, check your connections.
6. Move the item gently back and forth every few minutes, or use a magnetic stirrer on low.
7. For an even coat on a spoon or anything curved, turn it round halfway through, keeping it in the solution.
8. Plate for the time you calculated: 5–10 µm for display pieces, 20 µm or more for cutlery and anything handled daily.
9. Lift the item out, then switch off. Rinse twice in clean water, finishing with distilled water, and dry straight away with a soft cloth.

Step 10: Finishing

• Fresh silver plating comes out a soft, matt white. This is normal.
• Rub it with a burnisher or the back of a smooth steel spoon to bring up a shine, or buff very lightly with a soft cloth and a fine silver polish.
• Do not use a power buffing mop with coarse compound. It can cut through a thin coat in seconds.
• For display pieces that won't be handled, a clear anti-tarnish lacquer keeps the shine. Do not lacquer cutlery or anything that touches food.
• Store finished pieces with anti-tarnish strips or in tarnish-resistant cloth bags.

Looking After the Silver Solution

• Store it in a sealed, labelled container in a dark place. Many silver solutions are spoiled by light.
• Rinse well between every stage so no acid or nickel solution gets carried into it.
• Top up any loss from evaporation with distilled water only.
• If you use stainless steel anodes, the solution slowly runs out of silver. Top it up with the supplier's replenisher when plating becomes slow.
• Filter it if bits appear or the coat feels gritty.
• Keep a log of each item: area, current, time and result. It makes problems much easier to solve.

Troubleshooting

Safety and Waste

• No cyanide, ever: Only use cyanide-free solutions. If you are ever unsure what a solution contains, do not use it, and never let any plating solution meet acid.
• Silver solutions: Usually alkaline and harmful to eyes and skin. They stain skin, clothes and surfaces black. Wear goggles and gloves.
• Ammonia: Never mix silver solutions with ammonia or ammonia-based cleaners, and never leave silver solutions to dry out in open dishes. Some silver compounds formed this way can explode.
• Nickel salts (if mixing your own undercoat): Can cause skin allergy and are harmful if the dust is breathed in. Boric acid can harm fertility. Wear gloves and a dust mask when weighing powders.
• Acids: Give off corrosive fumes. Work with good ventilation and keep water within reach for eye splashes.
• Electricity: Use a low-voltage supply, keep mains leads and sockets away from liquids, and plug in through an RCD-protected socket.
• Storage: Labelled, sealed containers, out of reach of children and pets. Never store chemicals in food or drink bottles.
• Waste: Never pour plating solution or rinse water down a drain or onto the ground. Silver and nickel are harmful to aquatic life. Collect waste in sealed, labelled containers and take it to a hazardous waste facility. Some plating suppliers and refiners will recover silver from spent solution. If you plate as part of a business, trade waste rules apply, so use a licensed waste carrier.

Before You Switch On: Checklist

• Goggles, gloves and apron on, ventilation running.
• Solution is cyanide-free, at room temperature, and at the right pH.
• Current calculated and set on the supply.
• Item passed the water-break test and has not dried since its last rinse.
• Item on the NEGATIVE lead, anodes on the POSITIVE lead.
• Anodes either side of the item, 5–10 cm away.
• Power on before the item goes in (live entry).
• Timer set. Rinse tubs and a soft cloth ready.

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, as it may remove colour.
• Grease: Cornflour 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).

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.

7.1 Gilding

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; it should feel tacky but not transfer. 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.

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.

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. Practise 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.

Timeline

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 hot hide glue (reversible, and the correct choice on an antique), clamp 24 hours. Repair the split front rail: work in hide glue, 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

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.

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

• Document the condition of every piece at receipt (dated photographs)
• Obtain the client's declared value in writing before work begins
• Keep all quotes, correspondence, and invoices for at least 6 years
• Join a professional body: AMUSF, Guild of Master Craftsmen, BAFRA, or equivalent. Membership often includes basic insurance.
