How to Sand Wooden Cabinets Before Refinishing

Wooden cabinets are essential in kitchens, bathrooms, and storage spaces, but daily use leaves them scratched, stained, or with dull finishes. Sanding before refinishing is the crucial first step to restore smoothness and prepare the surface for stain, paint, or oil. This guide explains how to sand cabinets effectively for long-lasting beauty.

Why Cabinet Sanding Matters

Cabinets endure heavy use, and without sanding, new finishes won’t adhere properly. Blotches, peeling, or uneven staining are common if sanding is skipped. Proper sanding creates a smooth, clean surface that ensures professional-quality refinishing results.

Tools You’ll Need

• Random orbital sander for flat doors and panels
• Sanding blocks for frames and edges
• Sanding sponges for trim and carvings
• Wet/dry sandpaper sheets (80–220 grit)
• Vacuum and tack cloth
• Stain, paint, or cabinet-grade finish

Best Grit Sequence for Cabinets

• 80 grit: Removes old coatings, scratches, and water damage.
• 150 grit: Smooths doors, drawers, and side panels.
• 220 grit: Final prep before stain, paint, or sealer.

Step-by-Step: Sanding Wooden Cabinets

1. Prep cabinets. Remove doors, drawers, and hardware. Label pieces for easier reassembly.
2. Initial sanding. Begin with 80 grit (25-pack) to strip finishes and level imperfections.
3. Smooth surfaces. Switch to 150 grit (50-pack) for consistent sanding on doors and frames.
4. Final prep. Use 220 grit (100-pack) to achieve a finish-ready surface.
5. Clean thoroughly. Vacuum and tack cloth all surfaces to remove dust before finishing.

Special Cases

For veneer cabinets, sand lightly to avoid sanding through thin layers. Painted cabinets may require stripping before sanding. Antique cabinets with intricate trim should be hand-sanded to preserve detail.

Pro Tips

• Sand with the grain to avoid scratches showing under finish.
• Work door by door for thorough sanding.
• Test finishes on the inside of a cabinet door before applying everywhere.

Aftercare

• Protect finish: Use gentle cleaners and avoid harsh chemicals.
• Re-finish as needed: Light sanding with 220 grit before recoating extends cabinet life.
• Handle with care: Use liners inside drawers to reduce wear.

FAQs

• Do I need to sand to bare wood? Yes, if finishes are failing. For light updates, scuff sanding may suffice.
• What finish works best? Polyurethane for durability, stains for warmth, and paints for bold color.
• Can I sand by hand? Yes—especially for frames, corners, and carved details.
