4 steps, 10 tools, 11 materials

Overview

The Piece

• Restore 30-year-old solid wood kitchen cabinets with chipping high-gloss varnish.
• Check doors first: strip solid wood, or heavy-sand veneer and existing paint.
• Keep sturdy cabinet boxes and original soft-close hinges instead of buying new.

The Target Look

• Smooth, modern Pure White semi-gloss finish with gold bar pulls.
• Water-based urethane trim enamel prevents yellowing and withstands frequent cleaning.

What It Takes

• Plan for several weeks; quadruple your time estimate.
• Work in phases: finish upper cabinets before starting lowers.
• Expect chemical stripping mess, multi-coat drying waits and HVLP spray gun setup.

What Decides Success

• Strip and sand until no peeling varnish or residue remains.
• Shellac primer on bare wood blocks yellow tannin bleed under white paint.

Health and safety

Chemical Strippers and Solvents

• Wear chemical-resistant gloves, safety glasses, and protective clothing when applying gel paint strippers and after-wash cleaning solvents.
• Work outdoors or in a well-ventilated space when using strippers, after-wash solvents, and shellac-based primer to avoid strong fumes.
• Keep flammable after-wash solvents, shellac-based primer, and stripper residue away from heat sources, sparks, and open flames.
• Place scraped varnish sludge and solvent-soaked rags in a sealed metal container to prevent fire hazards and chemical exposure.

Sanding and Spray Painting

• Wear a respirator mask inside the spray tent when spraying water-based urethane enamel to keep atomized paint out of your lungs.
• Wear a dust mask and safety glasses when sanding bare wood, shellac-based primer, and enamel coats with 180 to 400 grit sandpaper.
• Avoid inhaling aerosol mist and work in fresh air when applying silicone spray lubricant to the cleaned cabinet hinges.

Compressor and Electrical Tools

• Keep the air compressor and cordless drill away from flammable cleaning solvents and shellac primer vapors to prevent spark ignition.
• Depressurize the air compressor hose before disconnecting the HVLP gravity feed spray gun for cleaning or refilling.
• Never point the pressurized HVLP spray gun or air compressor hose at yourself or anyone else.
• Unplug the ultrasonic cleaner before filling or emptying the tank, and keep electrical cords dry while cleaning hardware.

Scraping and Door Handling

• Push metal scrapers and wire brushes away from your hands and body to prevent slips and cuts while stripping varnish.
• Wear protective gloves when scrubbing with the wire brush so stiff bristles and chemical residue do not injure your hands.
• Support cabinet doors securely while removing or reinstalling hinges with the cordless drill so heavy doors do not drop.

The piece & its condition

• Thick 30-year-old high-gloss varnish is chipping and peeling on the wood.
• Scratches, dings and gouges mar the bare wood under the old finish.
• Detailed door trim grooves trap stubborn varnish that flat scrapers cannot reach.
• Without shellac primer, raw wood bleeds yellow tannins into white paint.
• Original 1990s soft-close hinges are stiff with old varnish and dust.

Finishes & supplies, in the order they go on

Before you start

Workspace

• Set up a ventilated stripping area and a plastic-lined spray tent.
• Set up a dust-free door drying station with painting pyramids.

Take It Apart

• Remove doors and original hinges before prepping surfaces.
• Box original hinges to deep-clean and reuse.

Test First

• Test chemical stripper on one door to check it cuts old varnish.
• Practice HVLP spray gun patterns on scrap cardboard before doors.

Step by step

Step 1: Strip, Sand, and Prep Cabinet Doors

Doors and boxes stripped to clean, smooth bare wood with gouges filled.

Watch this step (1:03)

You'll need: Chip Brush, Scrapers, Wire Brush, Paint & Varnish Stripping Gel, Premium Stripper, Paint Stripper After Wash, Sandpaper, Wood Filler

1. 1.1 Apply Chemical Stripper
   • Coat doors thickly with gel stripper using a chip brush.
   • Use heavy-duty gel stripper instead of mild if 30-year-old varnish resists.
   • Cover wet stripper with plastic cling wrap to prevent early drying.
   • Let chemical sit until high-gloss varnish bubbles and softens.
2. 1.2 Scrape Off Old Varnish
   • Lift softened varnish off flat panels with plastic and metal scrapers.
   • Scrub detailed trim profiles with a wire brush to pull varnish from corners.
   • Gently clean narrow grooves with a small flathead screwdriver.
   • Strip stubborn spots a second round until bare wood shows.
3. 1.3 Clean and Neutralize the Wood
   • Wipe stripped wood with paint stripper after-wash, removing chemical residue.
   • Let neutralized wood dry before sanding.
4. 1.4 Sand the Bare Wood
   • Sand bare wood with 180-grit sandpaper to remove varnish traces.
   • Work evenly across panels and profiles for porous primer tooth.
   • On unknown veneer or old paint, skip chemical stripping and heavy-sand.
5. 1.5 Fill Imperfections
   • Press wood filler into deep door scratches, dings, and gouges.
   • Let filler dry, then sand flush with the wood.
   • Wipe off sanding dust for a clean priming surface.

Key measurements

• Initial bare-wood sanding grit: 180 grit
• Stripper applications for thick varnish: 2 rounds

• Tip: Cover stripper with plastic wrap to keep gel wet and active longer.
• Tip: Clear soft varnish from tight trim grooves with a small flathead screwdriver.
• Heads up: Use strippers in a ventilated area with chemical-resistant gloves and eye protection.

Before you move on: Feel wood and check grooves so no glossy varnish, peeling, or chemical residue remains.

Step 2: Roll/Brush on Primer

Cabinet boxes and doors sealed with stain-blocking shellac primer and sanded smooth.

Watch this step (3:35)

You'll need: Paint Brush and Roller, Painting Pyramids, BIN Shellac-Base Primer, Sandpaper

1. 2.1 Apply Primer Coat
   • Lay cabinet doors flat on painting pyramids in the drying area.
   • Brush shellac primer into detailed grooves and roll flat areas.
   • Brush and roll instead of spraying; oil-based shellac resists water cleanup.
   • Let side one dry, then flip and prime side two.
2. 2.2 Sand the Primer
   • Lightly sand dried primer with 220-grit sandpaper.
   • Knock down brush marks and roller stipple until glass-smooth.
   • Wipe sanding dust off doors and cabinet boxes.

Key measurements

• Primer sanding grit: 220 grit
• Primer: 1 coat on door backs, fronts, and cabinet boxes

• Tip: Apply shellac-based primer under white paint to stop raw wood tannins bleeding yellow stains through.

Before you move on: Feel primed doors to check roller texture is flat and no raw wood shows.

Step 3: Spray Paint with HVLP

Doors and cabinets coated in smooth, drip-free Pure White urethane trim enamel.

Watch this step (4:48)

You'll need: HVLP Gravity Feed Spray Gun, Air Compressor, Spray Tent, Painting Pyramids, Emerald Urethane Trim Enamel, Sandpaper

1. 3.1 Prepare Paint and Sprayer
   • Line the spray tent with plastic sheets to contain overspray.
   • Stir the urethane trim enamel and pour through a mesh strainer.
   • Thin the paint slightly with water to flow through the HVLP gun; exact ratio is not specified, so follow sprayer manufacturer testing.
   • Connect the 20 oz gravity-feed HVLP spray gun and large air compressor.
2. 3.2 Spray the Doors
   • Spray light, even coats on cabinet door backs first.
   • Dry wet doors on painting pyramids in a closed, dust-free area.
   • Flip dry doors to spray fronts: two coats on backs, three on fronts and boxes.
   • Dry 4 to 6 hours between coats per the label.
3. 3.3 Sand Between Coats
   • Lightly sand with 400-grit sandpaper between dried coats.
   • Level dust nibs, blemishes, or minor drips before the next coat.
   • Wet-sand optionally with 800-grit sandpaper before the final coat for extra smoothness.
   • Wipe off sanding dust before the next enamel layer.

Key measurements

• Spray gun cup capacity: 20 oz
• Between-coat grit: 400 grit (optional 800-grit wet sand before final coat).
• Paint coats on door backs: 2 coats
• Door fronts and cabinet boxes: 3 coats.
• Dry time between coats: 4 to 6 hours

• Tip: Spray multiple thin coats, not one heavy coat, to prevent runs and sags.
• Tip: Paint one fewer coat on inside door backs to save time and material.
• Heads up: Wear a respirator mask while spray painting to protect lungs from atomized enamel.

Before you move on: Check dry doors in bright light for full white coverage without drips or dust nibs.

Step 4: Reassembly & Hardware

Install restored hinges and new gold bar pulls on cured doors, then hang level on the cabinets.

Watch this step (7:44)

You'll need: Ultrasonic Cleaner, Drill, Gold Bar Pulls, Silicone Lubricant

1. 4.1 Clean and Restore Hinges
   • Submerge dusty, varnish-coated original hinges in denatured alcohol in an ultrasonic cleaner.
   • Run the cleaner until old varnish lifts to bare factory metal.
   • Dry hinges; spray moving joints with silicone lubricant for smooth motion.
2. 4.2 Measure and Drill for New Handles
   • Pick larger gold bar pulls for big doors, smaller pulls for small doors.
   • Put painter's tape over handle spots and mark hole centers.
   • Drill handle holes through the tape to keep fresh paint from chipping.
3. 4.3 Install Hardware and Rehang Doors
   • Wait an extra 1 to 2 days after the final coat before handling doors for reassembly.
   • Screw new gold bar pulls and cleaned original hinges to the doors.
   • Hang doors on cabinet boxes; adjust hinge screws until level.

Key measurements

• Reassembly wait: 1 to 2 extra days after final coat.
• Full paint cure time: up to 1 month

• Tip: Reuse original soft-close hinges to avoid drilling new hinge cup holes and re-leveling doors from scratch.
• Heads up: Do not rush reassembly; uncured enamel scratches and dings before hardening.

Before you move on: Open and close each door; check for smooth hinges, straight pulls, and even gaps.

Finishing

Cure

• Let paint dry to the touch 4 to 6 hours between coats.
• Wait 1 to 2 extra days before reinstalling hardware and doors.
• Handle doors gently up to 1 month until urethane enamel cures hard.

Care

• Wipe cured urethane enamel with mild soap and water as needed.
• Water-based urethane enamel resists yellowing over time, unlike oil-based topcoats.

Reassembly

• Reinstall cleaned factory hinges in existing holes to keep alignment.
• Match bar pull lengths to door sizes for balanced proportions.

Alternatives

• Heavy-sand instead of chemically stripping over sound paint or veneer.
• Pair Pure White uppers with Muddled Basil (SW 7745) accent stacks.
