Sanding Between Coats of Paint on Cabinets: Smooth, Durable Finish (220–400 Grit Guide)

Painting kitchen or bathroom cabinets is one of the most popular DIY upgrades. For a silky, professional look, sanding between coats of paint is essential. This guide explains the grit sequence and steps for flawless cabinet finishes.

Why Sand Between Paint Coats?

Sanding removes dust nibs, brush marks, and raised grain. It also helps the next coat of paint bond better, ensuring durability and a polished final appearance.

Best Tools for Cabinet Paint Sanding

• 9x11 in silicon carbide sandpaper sheets
• Sanding sponge for detailed edges
• Tack cloth or microfiber rag
• Vacuum with brush attachment
• Dust mask for safety

Recommended Grit Sequence

• 220 grit: First sanding after base coat.
• 320 grit: Smooth mid-coats.
• 400 grit: Final sanding before topcoat.

Step-by-Step: Sanding Cabinets Between Paint Coats

1. Let coat dry. Wait until paint is fully cured before sanding.
2. Start with 220 grit. Lightly sand base coat. Use 220 Grit (25-pack).
3. Clean thoroughly. Remove dust with tack cloth or vacuum.
4. Move to 320 grit. Sand mid-coats for smoothness. Try 320 Grit (50-pack).
5. Finish with 400 grit. Sand before the last coat for silky results. Stock up on 400 Grit (100-pack).
6. Apply final coat. Brush or spray evenly for a flawless finish.
7. Optional buffing. After full cure, buff with ultra-fine sandpaper or polishing pads for extra gloss.

Special Cases

For glossy paint, finish sanding with 600 grit for a mirror-like surface. For matte finishes, stopping at 320–400 grit is enough.

Pro Tips

• Work in a dust-free area to prevent particles settling in paint.

Aftercare

• Allow paint to cure fully (at least 7 days) before reinstalling hardware.
• Clean with mild soap and water only.
• Avoid harsh chemicals that can damage paint.
