How to Sand Wooden Patio Furniture for Outdoor Refinishing (80–220 Grit)

Patio furniture endures constant sun, rain, and heavy use, leading to faded finishes, rough patches, and splinters. Sanding restores smoothness and prepares the wood for staining, painting, or sealing, extending the life of your outdoor set.

Why Sand Patio Furniture?

Sanding removes weathered layers, old coatings, and imperfections. It also ensures new finishes adhere properly, preventing peeling and boosting durability.

Tools You’ll Need

• Orbital sander for flat tabletops and seats
• Sanding sponges for curves, legs, and armrests
• Wet/dry sandpaper sheets (80–220 grit)
• Vacuum or outdoor blower
• Protective gear: mask, goggles, gloves

Recommended Grit Sequence

• 80 grit: Removing old finishes and weathered surfaces.
• 120 grit: General smoothing after coarse sanding.
• 180 grit: Preparing wood for stain or sealer.
• 220 grit: Final sanding for smooth touchable finishes.

Step-by-Step Process

1. Clean and inspect. Wash furniture with mild soap and water, then let dry fully.
2. Start with 80 grit. Use 80 grit (25-pack) to strip weathered wood and old coatings.
3. Refine with 120 grit. Smooth seating and tabletop areas using 120 grit (50-pack).
4. Prep with 180 grit. Use 180 grit (50-pack) before applying finish.
5. Finish with 220 grit. Lightly sand with 220 grit (100-pack) for a polished result.
6. Clean thoroughly. Vacuum or blow off dust, then wipe with tack cloths.
7. Apply finish. Stain, paint, or seal with exterior-grade products.

Special Cases

For teak or hardwood furniture, avoid sanding finer than 220 grit, as smoother surfaces reduce stain absorption. For painted furniture, scuff sanding may be enough before repainting.

Pro Tips

• Sand with the grain for smoother results.
• Use sanding sponges for curved arms and legs.
• Work in dry weather to prevent moisture trapping.
• Apply multiple thin coats of finish for durability.

Aftercare

• Cover or store patio furniture in winter months.
• Clean with mild soap and water to prevent buildup.
• Reapply protective coatings every 1–2 years.

FAQs

• Do I need to sand to bare wood? Yes, for staining. For repainting, light sanding is often enough.
• Can I sand patio furniture by hand? Yes—hand sanding is effective for edges and curves.
• What grit is best before sealing? 180–220 grit ensures both smoothness and absorption.
