Refinishing Kitchen Cabinets with Sandpaper (80, 150, 220, 320 Grit Guide)
Kitchen cabinets take daily abuse—grease, fingerprints, and constant use wear down finishes over time. Instead of replacing them, refinishing with the right sanding approach can bring cabinets back to life. With the proper grit sequence, you’ll achieve a smooth surface that holds paint or stain beautifully.
Why Sand Cabinets Before Refinishing?
Cabinets often have layers of finish or paint that prevent new coatings from sticking. Sanding removes old layers, smooths imperfections, and opens the wood grain for stronger adhesion. Done correctly, it ensures your hard work lasts for years.
Tools You’ll Need
- Orbital sander for large, flat panels
- Sanding block or sponge for edges
- Vacuum and tack cloth
- Protective mask and goggles
- Assorted sandpaper sheets
Best Grit Sequence for Cabinet Refinishing
- 80 grit (50-pack) — Removes old paint, varnish, or heavy grime.
- 150 grit (25-pack) — Smooths rough sanding marks and evens out the surface.
- 220 grit (100-pack) — Prepares the wood for primer or stain.
- 320 grit (25-pack) — Final finish sanding before paint or clear coat.
Step-by-Step: Sanding Kitchen Cabinets
- Remove doors and hardware. Label each door for easy reassembly.
- Strip with 80 grit. Use 80 grit sandpaper to take off old coatings and surface dirt.
- Smooth with 150 grit. Switch to 150 grit sheets to eliminate scratches from coarse sanding.
- Prep with 220 grit. Sand the wood evenly using 220 grit sheets before applying primer.
- Finish with 320 grit. Use 320 grit sandpaper to ensure a silky surface for the final finish.
- Vacuum and wipe. Remove all dust before painting or staining.
Special Cases
- Laminate cabinets: Lightly scuff with 220 grit only—too much sanding can damage laminate.
- Painted cabinets: Start with 150 grit unless the old paint is peeling heavily.
- Detailed trim: Use sanding sponges to reach grooves and edges.
Pro Tips
- Always sand with the grain to avoid cross scratches.
- Change sandpaper frequently—dull sheets leave uneven marks.
- Use a bright work light to check for flaws before applying finish.
Aftercare
- Seal cabinets with a durable clear coat to withstand kitchen humidity.
- Clean only with mild soap—avoid harsh chemicals that damage finishes.
- Touch up scratches promptly to extend the life of the finish.
FAQs
- Can I use liquid deglosser instead of sanding? It helps, but sanding still gives better adhesion.
- Do I need to sand between paint coats? Yes, a light pass with 320 grit ensures a smooth finish.
- What if my cabinets are MDF? Sand very lightly—coarse grits can damage the material.
