How to Sand Wooden Cabinets for Refinishing (80–320 Grit)

Wooden cabinets in kitchens and bathrooms face constant use, grease, and moisture. Over time, finishes wear down, paint peels, and wood becomes dull. Sanding is the first step to refreshing cabinets before painting or staining.

Why Sand Cabinets?

Sanding removes old finishes, smooths scratches, and ensures new paint or stain adheres properly. It also evens out surfaces for a professional-looking result.

Tools You’ll Need

• Orbital sander for cabinet doors and drawer fronts
• Sanding sponges for edges and grooves
• Wet/dry sandpaper sheets (80–320 grit)
• Vacuum and tack cloth
• Mask, goggles, gloves

Recommended Grit Sequence

• 80 grit: Removing heavy finishes or peeling paint.
• 120 grit: Smoothing after coarse sanding.
• 220 grit: Prepping wood for paint or stain.
• 320 grit: Final sanding for a polished surface.

Step-by-Step Process

1. Remove hardware. Take off handles, hinges, and knobs for easier sanding.
2. Start with 80 grit. Use 80 grit (25-pack) to strip finishes and rough areas.
3. Refine with 120 grit. Smooth cabinet doors and drawer fronts with 120 grit (50-pack).
4. Prep with 220 grit. Sand evenly with 220 grit (100-pack) before finishing.
5. Finish with 320 grit. Lightly sand with 320 grit (25-pack) for smoothness.
6. Clean thoroughly. Vacuum dust and wipe surfaces with tack cloths.
7. Apply finish. Prime, then paint or stain for a durable coating.

Special Cases

For laminate cabinets, light scuff sanding with 220 grit may be enough. For antique cabinets, stick to fine grits (180–320) to preserve original details.

Pro Tips

• Sand with the grain for cleaner results.
• Label cabinet doors before removing them to avoid confusion.
• Prime before painting for long-lasting durability.
• Work in sections to maintain consistency.

Aftercare

• Clean cabinets regularly with mild soap and water.
• Touch up scratches promptly to prevent deeper damage.
• Reapply protective finishes every few years as needed.

FAQs

• Do I need to sand to bare wood? Yes, for staining. For repainting, scuff sanding may be enough.
• Can I sand cabinets by hand? Yes—hand sanding works best for edges and grooves.
• What grit is best before painting? 220 grit provides excellent adhesion and smoothness.
