Sanding Wooden Dining Tables Before Refinishing: Grit Guide for a Smooth, Durable Finish

Dining tables are the centerpiece of family meals, but daily use leaves them scratched, stained, and worn. Refinishing restores their beauty, but sanding is the foundation of the process. This guide explains the grit sequence and step-by-step process for sanding dining tables before refinishing.

Why Sand Dining Tables Before Refinishing?

Sanding removes old finishes, smooths imperfections, and opens the grain so stain or paint adheres properly. Without sanding, finishes may appear blotchy, peel quickly, or fail to protect the table effectively.

Tools You’ll Need

• Sandpaper sheets in multiple grits
• Orbital sander for flat surfaces
• Sanding block or sponge for legs and edges
• Tack cloth or microfiber rag
• Protective gear (mask, gloves, safety glasses)

Best Grit Sequence for Dining Tables

• 100 grit: Removes old finishes and rough areas.
• 150 grit: Smooths the surface and evens scratches.
• 220 grit: Final sanding for an even, finish-ready surface.

Step-by-Step: Sanding Dining Tables for Refinishing

1. Prep the table. Remove leaves, hardware, or inserts. Clean surfaces thoroughly.
2. First sanding pass. Use 100 grit (50-pack) to strip finishes and smooth dents.
3. Smooth with 150 grit. Switch to 150 grit (100-pack) for consistent texture.
4. Final sanding. Apply 220 grit (25-pack) before staining or painting.
5. Edge sanding. Use folded sheets or sponges for corners, table legs, and trim.
6. Clean thoroughly. Vacuum dust and wipe with a tack cloth.
7. Apply finish. Stain to enhance natural wood grain, or paint for a fresh look, then seal with polyurethane for durability.

Special Cases

For veneer dining tables, avoid sanding below 120 grit to prevent sanding through. For antique tables, sand lightly with finer grits to preserve character.

Pro Tips

• Sand with the grain for a smoother look.
• Don’t oversand—finishes need slight texture to bond effectively.
• Sand lightly between coats of finish with 320 grit for extra smoothness.

Aftercare

• Let finishes cure fully before placing items back on the table.
• Use placemats or coasters to prevent scratches and stains.
• Clean with mild soap and water only—avoid abrasive cleaners.

FAQs

• Do I need to sand if I’m just recoating? Yes—light sanding ensures adhesion between old and new finishes.
• Can I stop at 150 grit? Not recommended—220 grit prepares the surface best for stain or paint.
• What if the table has deep scratches? Fill with wood filler before the final sanding pass.
