Sanding Cabinets Before Painting: Grit Sequence for a Flawless Finish

Painting cabinets can transform a kitchen or bathroom, but sanding is the most critical step for a lasting, professional finish. Without sanding, paint may peel or show imperfections. This guide explains the grit sequence and process for sanding cabinets before painting.

Why Sand Cabinets?

Cabinets are exposed to grease, oils, and daily wear. Sanding removes old finishes, smooths scratches, and creates a surface that primer and paint can grip. Skipping this step risks poor adhesion and uneven coverage.

Tools You’ll Need

• Sandpaper sheets in multiple grits
• Sanding block or orbital sander
• Tack cloth or microfiber rag
• Vacuum or shop vac
• Painter’s tape and drop cloths

Best Grit Sequence for Cabinets

• 120 grit: Removes old finish and rough spots.
• 180 grit: Smooths surface and evens texture.
• 220 grit: Final sanding before primer and paint.

Step-by-Step: Sanding Cabinets

1. Prep the cabinets. Remove doors, drawers, and hardware for easier sanding.
2. First sanding pass. Use 120 grit (25-pack) to remove finish and level imperfections.
3. Smooth with 180 grit. Switch to 180 grit (100-pack) for a refined surface.
4. Final sanding. Apply 220 grit (25-pack) before primer for best adhesion.
5. Clean thoroughly. Vacuum dust and wipe with a tack cloth.
6. Prime and paint. Apply primer, then finish with your chosen cabinet paint.

Special Cases

For laminate cabinets, sand lightly with 220 grit to scuff the surface. For oak or textured wood, fill open grain with wood filler before the final sanding.

Pro Tips

• Always sand with the grain to avoid visible scratches.
• Label doors and drawers before removal to simplify reinstallation.
• Wet sanding with 220 grit creates a smoother base for glossy paints.

Aftercare

• Allow cabinets to cure fully before reinstalling hardware.
• Clean painted cabinets with mild soap and water—avoid abrasives.
• Touch up scratches promptly to extend the life of the finish.

FAQs

• Do I need to sand between coats of paint? Light sanding with 320 grit helps ensure smooth coats.
• Can I skip primer? No—primer is essential for paint adhesion, especially on cabinets.
• What if the cabinets are very glossy? Sand extra thoroughly with 220 grit for adhesion.
