How to Sand Wooden Picnic Tables for Outdoor Refinishing (60–220 Grit)

Picnic tables endure constant exposure to weather, food spills, and heavy use. Over time, surfaces become rough, finishes peel, and wood fibers raise. Sanding is the first step in restoring picnic tables for safe, smooth, and long-lasting use.

Why Sand Picnic Tables?

Sanding removes splinters, old finishes, and weathered wood. It ensures new stain, paint, or sealant adheres properly and prevents rough surfaces from causing discomfort.

Tools You’ll Need

• Orbital sander for tabletops and benches
• Sanding sponges for edges and legs
• Wet/dry sandpaper sheets (60–220 grit)
• Vacuum or outdoor blower
• Mask, goggles, gloves

Recommended Grit Sequence

• 60 grit: Removing old paint, stain, or rough weathered wood.
• 100 grit: General smoothing after coarse sanding.
• 150 grit: Preparing wood for stain or paint.
• 220 grit: Final sanding for a smooth, comfortable surface.

Step-by-Step Process

1. Inspect the table. Check for loose nails or damaged boards and repair before sanding.
2. Start with 60 grit. Use 60 grit (25-pack) to remove heavy weathering and old finishes.
3. Refine with 100 grit. Smooth tabletops and benches using 100 grit (100-pack).
4. Prep with 150 grit. Sand evenly with 150 grit (25-pack) before finishing.
5. Finish with 220 grit. Lightly sand with 220 grit (50-pack) for smooth, splinter-free results.
6. Clean thoroughly. Vacuum or blow away dust and wipe with tack cloths.
7. Apply finish. Use exterior-grade stain, paint, or sealer to protect from weather.

Special Cases

For softwoods like pine, avoid sanding finer than 220 grit, as it reduces stain absorption. For hardwood picnic tables, sanding up to 220 grit provides a sleek, polished finish.

Pro Tips

• Sand with the grain for best results.
• Use sanding sponges on edges and curved supports.
• Seal all cut ends and joints to prevent water damage.
• Apply multiple thin coats of finish for durability.

Aftercare

• Clean picnic tables with mild soap and water regularly.
• Cover or store during winter months to extend life.
• Reapply stain or sealer every 2–3 years for protection.

FAQs

• Do I need to sand to bare wood? Yes, for staining. For repainting, scuff sanding is often enough.
• Can I sand picnic tables by hand? Yes—hand sanding works for legs and small areas, but machines save time for large surfaces.
• What grit is best before sealing? 150–220 grit ensures smoothness and finish absorption.
