How to Sand Between Coats of Paint on Wood for a Smooth Finish (220–400 Grit Guide)

When painting wood furniture, cabinets, or trim, the secret to a professional-looking finish is sanding between coats. This extra step levels out imperfections, helps paint layers bond better, and results in a silky smooth surface that looks flawless once completed.

Why Sand Between Paint Coats?

Even with high-quality paint, brush marks, lint, and dust specks can settle on the surface. Sanding lightly between coats ensures each new layer sticks evenly and prevents the paint job from looking rough or streaky.

Best Sandpaper Grits for Paint Sanding

• 220 grit: First sanding between primer and base coat.
• 320 grit: General-purpose sanding between coats of paint.
• 400 grit: Ultra-smooth finish before the final coat.

Tools You’ll Need

• Fine-grit sandpaper sheets (220–400 grit).
• Sanding block for flat areas.
• Sponge sander for contoured trim or details.
• Tack cloth or microfiber rag.

Step-by-Step: Sanding Between Paint Coats

1. Let the paint dry fully. Wait at least 24 hours before sanding.
2. Start with 220 grit. Use 220 grit (25-pack) after primer to smooth the surface before applying the first coat of paint.
3. Sand lightly between coats. Switch to 320 grit (100-pack) for intermediate sanding.
4. Finish with 400 grit. Before the final coat, polish the surface with 400 grit (50-pack) to achieve a silky-smooth base.
5. Remove dust. Wipe thoroughly with a tack cloth or damp microfiber rag.
6. Apply next coat. Use smooth, even strokes with a brush or roller for best results.

Special Cases

For glossy paints, sanding between coats is critical to ensure adhesion. For matte finishes, sanding is less noticeable but still improves durability. If you’re painting outdoor furniture, sanding between coats adds longevity against weather exposure.

Pro Tips

• Don’t sand aggressively—light pressure is enough.
• Sand with the grain on wood surfaces to prevent scratches.
• Work in a dust-free space to avoid particles settling back on wet paint.

Aftercare

• Allow final coat to cure fully before heavy use (up to 7 days).
• Clean painted surfaces gently with mild soap and water.
• Touch up small chips by lightly sanding and repainting.

FAQs

• Do I always need to sand between coats? For best results—yes. Skipping may lead to visible brush marks.
• Can I wet sand paint? Yes, use fine wet/dry paper (400 grit) for the final coat prep.
• Will sanding remove the paint? Not if done lightly—you're only scuffing the surface.
