Prepping Wooden Cabinets for Stain or Paint (100, 150, 220, 320 Grit Guide)

Cabinets take heavy daily use, and over time finishes wear out, paint chips, or grease builds up. Sanding is the most important step before applying stain or paint, ensuring a smooth and durable surface. With the correct grit sequence, cabinets can look brand new again without replacing them.

Why Sand Cabinets?

Sanding removes dirt, old finishes, and surface imperfections. It also opens the grain of the wood, helping stain or primer penetrate more effectively. Skipping sanding can result in poor adhesion, blotchy finishes, and reduced lifespan of coatings.

Tools You’ll Need

• Orbital sander for flat cabinet panels
• Sanding sponges for edges and corners
• Vacuum and tack cloth
• Protective mask and goggles
• Assorted wood sanding sheets

Best Grit Sequence for Cabinets

• 100 grit (100-pack) — Removes light finishes and surface imperfections.
• 150 grit (25-pack) — Smooths sanding marks and evens the surface.
• 220 grit (100-pack) — Prepares wood for primer, stain, or paint.
• 320 grit (25-pack) — Final sanding pass for a silky, finish-ready surface.

Step-by-Step: Sanding Cabinets

1. Prep the area. Remove doors, hardware, and clean with degreaser.
2. Start with 100 grit. Use 100 grit sandpaper to remove old coatings and level surfaces.
3. Smooth with 150 grit. Switch to 150 grit sheets for consistent texture.
4. Refine with 220 grit. Apply 220 grit sheets before staining or priming.
5. Finish with 320 grit. Use 320 grit sandpaper to achieve a flawless finish.
6. Clean thoroughly. Vacuum dust and wipe with tack cloth before coating.

Special Cases

• Grease-stained cabinets: Clean thoroughly before sanding to avoid clogging paper.
