How to Refinish Kitchen Cabinets

Why this matters

Kitchen cabinet refinishing is the most profitable single-day-to-week project a painter sells. A typical midsize kitchen sells for a fraction of what full replacement runs, often a third or less. Customer keeps their layout + functional cabinets, painter earns more per labor-hour than wall painting, + the result drives referrals because kitchens are the photographed room of every home.

Done wrong (no degrease, no bonder, wrong paint), the finish fails within 18 months + the customer destroys the painter's reputation.

When refinishing works

Good candidates:

• Solid wood doors + face frames (real wood, not thermofoil)
• Cabinet boxes in sound condition
• Customer accepts new color (not staining to original)
• Doors flat or simple shaker style (highly detailed routes hide drips)

Poor candidates:

• Thermofoil doors (peeling lamination - needs replacement, not paint)
• Particleboard with delamination
• Heavily damaged or sticky doors (kitchen grease saturation impossible to fully remove)
• Customer expects spray-shop quality with a brush - set expectations

Process options

Spray refinish in-place: doors removed + shop-sprayed; boxes brushed + rolled in kitchen. Best balance for residential. 3-7 days work, customer kitchen-unavailable that period.

Spray refinish off-site: doors + boxes (where possible) removed + shop-sprayed. Highest quality. Customer kitchen down 1-2 weeks. Highest cost.

Brush + roll in-place: lowest cost, longest customer disruption (more coats to hide brush marks), most-prone to fingerprint marks during cure.

Most contracts: in-place with shop-sprayed doors. Customer keeps the kitchen functional 80% of project time.

Tools + materials

• HVLP sprayer (Graco 9.5, Fuji Q5, Wagner FLEXiO) or airless (Graco FinishPro)
• Spray booth at shop (filter wall + extraction)
• Degreaser (Krud Kutter Original or TSP substitute)
• Sandpaper: 120-grit, 220-grit, 320-grit
• Bonding primer (Stix, INSL-X Cabinet Coat primer, BIN - choose by paint type)
• Topcoat (water-based alkyd, urethane-acrylic, lacquer, or 2K-poly - see below)
• Tack cloth
• Painter's tape (FrogTape Delicate Surface for trim) + drop cloths
• Plastic sheeting + zip walls
• Labeling system (numbered tags or photos for every door)
• Hardware bags (sandwich bags, labeled, for hinges + handles)
• Bondo or wood filler for dings
• Foam roller covers (4" white foam, mini)
• Brush (Purdy XL Glide, 2.5" sash)

Paint chemistry choices

Different products, different finishes + durability:

For most residential: water-based alkyd (Advance or Emerald Urethane) for in-place; pre-cat lacquer for shop-sprayed. Bondable, durable, customer-paintable later.

Procedure

Step 1: Customer alignment

1. Color sample on a door - wet sample (not chip) approved
2. Sheen approved (typical satin)
3. Hardware: re-use, replace, fill old holes for new positions
4. Inside-of-cabinet scope: paint inside (premium), interior left wood, or interior shelf-paper

Step 2: Label + remove

1. Open + photograph every door
2. Numbered tape on door + on cabinet frame (matching)
3. Remove hinges + hardware to labeled bags
4. Stack doors in transport racks for shop
5. Remove drawers + drawer fronts

Step 3: Degrease + sand (boxes)

In kitchen:

1. Degrease ALL surfaces - kitchen oil/grease is everywhere
2. Sand 220-grit by hand
3. Tack cloth
4. Vacuum + tack again
5. Repair dings with wood filler, sand smooth
6. Tape backsplash, counters, floors with masking + plastic

Step 4: Prime boxes

1. Brush + roll bonding primer
2. One coat usually sufficient; two if existing finish is glossy or stained
3. Light scuff sand with 320-grit between coats
4. Tack cloth + vacuum

Step 5: Topcoat boxes

1. Brush face frames with synthetic-bristle brush (Purdy XL Glide)
2. Roll panels with 4" foam mini-roller
3. Two coats minimum; three if pure white over wood
4. Light scuff sand between coats
5. Final coat: brush in one direction, then tip-off light

Step 6: Shop-spray doors

In shop booth:

1. Degrease door
2. Sand 220-grit, tack
3. Bonding primer sprayed
4. Cure per manufacturer (typically 4-24 hours)
5. Scuff with 320-grit
6. Topcoat #1
7. Cure
8. Scuff 400-grit
9. Topcoat #2
10. Cure flat for 24-48 hours before stacking

Step 7: Hardware reinstall

1. Doors back to numbered positions
2. Hinges reattached
3. Door alignment check + adjust
4. New hardware drilled (template) OR reused
5. Bumpers replaced

Step 8: Cure + customer briefing

Cabinet enamels are NOT fully cured at delivery. Customer must:

• Not slam doors for 7-14 days
• Not stack heavy items on shelves for 7 days
• Wash with mild soap + water only (no abrasives) for 30 days
• Full hardness at 30 days (water-based alkyd)

Hand the customer a printed care sheet - prevents 50% of warranty complaints.

Acceptance criteria

• Even coverage, no drips, no brush marks
• Doors operate freely + line up
• Hardware reinstalled
• Customer signed + has touch-up paint can (labeled)
• Photos of completion

Common pitfalls

• No degreasing: paint peels in 6-12 months. Most common warranty fail
• Skipping bonding primer: paint scratches off with fingernail
• Wrong paint chemistry: regular wall paint on cabinets - fingerprints permanent within a week
• Spraying without booth: overspray everywhere, dust contamination
• Returning warm doors to stack: stick + tear finish
• No customer care sheet: customer slams doors at day 3, ruins finish, blames painter
• Pricing like wall painting: cabinet work is 3-5x the labor per square foot

Safety considerations

• Solvent spray: respirator (P100 + organic vapor cartridge) mandatory
• Spray booth filters changed regularly
• Sanding dust: HEPA vacuum + dust mask
• Kitchen access: keep customer out during spray + tack-time
• Pets confined; food + dishes covered
