How to Sand Wooden Cabinets Before Painting or Staining (80–400 Grit)

Cabinets are high-traffic surfaces in kitchens, bathrooms, and storage areas. Over time, grease, moisture, and daily use wear down finishes. Sanding is the most important prep step before painting or staining cabinets for a lasting, professional look.

Why Sand Cabinets?

Sanding removes glossy coatings, scratches, and imperfections. It ensures paint, stain, or sealer bonds properly, preventing peeling or uneven absorption.

Tools You’ll Need

• Orbital sander for flat cabinet doors
• Sanding sponges for trim and molding
• Wet/dry sandpaper sheets (80–400 grit)
• Vacuum and tack cloth
• Protective mask, goggles, and gloves

Recommended Grit Sequence

• 80 grit: Removing paint, varnish, or stubborn coatings.
• 120 grit: General smoothing after coarse sanding.
• 220 grit: Prepping bare wood before primer or stain.
• 320–400 grit: Final sanding for silky smooth surfaces.

Step-by-Step Process

1. Remove cabinet doors and hardware. Label hinges and screws for easy reassembly.
2. Start with 80 grit. Use 80 grit (25-pack) to strip finishes.
3. Refine with 120 grit. Smooth surfaces with 120 grit (50-pack) wet/dry sheets.
4. Prep with 220 grit. Sand with 220 grit (100-pack) before applying paint or stain.
5. Finish with 320–400 grit. Use 400 grit (10-pack) for polished smoothness.
6. Clean thoroughly. Vacuum dust and wipe with tack cloths.
7. Apply finish. Prime before painting or apply stain and sealer directly.

Special Cases

For laminate cabinets, scuff-sanding with 220 grit is usually enough. For oak cabinets, sanding to 320–400 grit reduces grain raising, resulting in a smoother painted finish.

Pro Tips

• Sand with the grain for consistent results.
• Use sanding sponges for trim, grooves, and corners.
• Prime before painting for stronger adhesion.
• Replace sandpaper often for cleaner cuts.

Aftercare

• Wipe cabinets with mild soap and water—avoid harsh chemicals.
• Reapply protective finishes every 3–5 years in high-use areas.
• Use gentle cleaners to prolong finish durability.

FAQs

• Do I need to sand to bare wood? Only if staining. For painting, scuff sanding is enough.
• Can I sand by hand? Yes—especially effective for edges and moldings.
• What grit is best before painting? 220 grit ensures adhesion and smoothness.
