Refinishing Kitchen Cabinets: Sanding for a Smooth Paint or Stain (80–320 Grit Guide)

Refinishing kitchen cabinets is one of the most cost-effective ways to update your kitchen. The secret to a professional-looking result lies in proper sanding. By using the right grit sequence, you can remove old finishes, smooth imperfections, and prepare the wood for new paint or stain.

Why Sand Cabinets Before Refinishing?

Cabinets endure constant wear, grease, and moisture. Sanding removes old coatings and rough spots, ensuring that your new finish adheres properly and looks flawless. Skipping sanding can lead to peeling paint or uneven stain absorption.

Best Tools for Cabinet Sanding

• 9x11 in silicon carbide sandpaper sheets (wet or dry use)
• Orbital sander or sanding block
• Tack cloth or vacuum with brush attachment
• Respirator or dust mask
• Protective gloves and eye protection

Recommended Grit Sequence

• 80 grit: Strip old finishes or heavy varnish.
• 120 grit: Smooth surfaces after stripping.
• 180 grit: Prep bare wood for stain or primer.
• 220–320 grit: Final smoothing for flawless finishes.

Step-by-Step: Sanding Kitchen Cabinets

1. Remove doors and hardware. Label each piece for easy reinstallation.
2. Start with 80 grit. Strip off old varnish or paint layers. Use 80 Grit (25-pack).
3. Smooth with 120 grit. Even out sanding marks and prepare surfaces. Try 120 Grit (50-pack).
4. Refine with 180 grit. Sand along the grain for a clean, uniform texture. Stock up on 180 Grit (100-pack).
5. Finish with 220–320 grit. Lightly sand before staining or painting for a silky-smooth surface.
6. Clean thoroughly. Vacuum dust and wipe down with a tack cloth.
7. Prime or stain. Apply your chosen finish for a fresh, updated look.

Special Cases

For laminate cabinets, avoid aggressive sanding. Instead, scuff with 220 grit to create a bonding surface for primer.

Pro Tips

• Always sand with the grain to avoid scratches.
• Replace sandpaper sheets often—clogged sheets reduce efficiency.
• Work in a ventilated area and wear protective gear.
• Test stain or paint on a small hidden area first.

Aftercare

• Let finishes cure fully before reattaching hardware.
• Clean cabinets with mild soap and water—avoid harsh chemicals.
• Use felt bumpers on doors to prevent chipping the finish.

FAQs

• Can I paint cabinets without sanding? Light sanding is always recommended for adhesion, even if using primer labeled as “no-sand.”
• Do I need to sand between coats of paint? Yes, lightly with 320 grit for the smoothest finish.
• How do I handle intricate cabinet details? Fold sandpaper or use sanding sponges to reach grooves and carvings.
