How to Sand Wooden Cabinets for a Smooth Kitchen Makeover (80–400 Grit)

Kitchen and bathroom cabinets face heavy use, grease, and moisture, making refinishing a challenge. Sanding is the foundation for achieving a professional makeover—whether painting, staining, or sealing.

Why Sand Cabinets?

Sanding removes old finishes, dulls glossy coatings, and smooths imperfections so new paint or stain bonds properly. Without sanding, coatings may peel, chip, or show flaws underneath.

Tools You’ll Need

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

Recommended Grit Sequence

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

Step-by-Step Process

1. Remove doors and hardware. Label hinges and handles for easy reassembly.
2. Start with 80 grit. Use 80 grit (25-pack) to strip coatings and rough surfaces.
3. Refine with 120 grit. Smooth doors and frames with 120 grit (50-pack) wet/dry sheets.
4. Prep with 220 grit. Sand surfaces evenly using 220 grit (100-pack) for finish adhesion.
5. Finish with 320–400 grit. Lightly sand with 400 grit (10-pack) for ultra-smooth results.
6. Clean thoroughly. Vacuum dust and wipe with tack cloths.
7. Apply finish. Prime, paint, or stain depending on your desired look.

Special Cases

For laminate cabinets, scuff-sanding with 220 grit may be enough to prep for bonding primer. For oak cabinets, sanding up to 400 grit reduces grain raising for smoother paint finishes.

Pro Tips

• Always sand with the grain of the wood.
• Use sanding sponges for grooves, molding, and curved trim.
• Clean between grit changes to avoid embedding dust.
• Apply primer before painting for lasting durability.

Aftercare

• Clean cabinets with mild soap—avoid harsh chemicals.
• Touch up finishes as needed in high-traffic areas.
• Reapply protective coatings every few years for longevity.

FAQs

• Do I need to sand to bare wood? Only if staining—scuff sanding is enough for repainting.
• Can I sand cabinets by hand? Yes, especially for edges and trim details.
• What grit is best before painting? 220 grit provides the right balance for adhesion and smoothness.
