How to Sand Wooden Garden Benches for Refinishing (80–220 Grit)

Garden benches are exposed to sun, rain, and heavy use, often resulting in faded finishes, splinters, and rough patches. Sanding is the essential step to restore benches before staining, painting, or sealing for outdoor durability.

Why Sand Garden Benches?

Sanding removes weathered wood, splinters, and old finishes. It ensures new coatings adhere properly, prevents discomfort, and enhances the natural beauty of the wood.

Tools You’ll Need

• Orbital sander for flat seating surfaces
• Sanding sponges for arms, legs, and curved backs
• Wet/dry sandpaper sheets (80–220 grit)
• Vacuum or outdoor blower
• Mask, goggles, gloves

Recommended Grit Sequence

• 80 grit: Removing old paint, stain, or rough fibers.
• 120 grit: Smoothing after coarse sanding.
• 180 grit: Preparing surfaces for stain or paint.
• 220 grit: Final sanding for comfort and smoothness.

Step-by-Step Process

1. Inspect the bench. Repair or replace damaged boards and tighten loose screws.
2. Start with 80 grit. Use 80 grit (25-pack) to strip finishes and remove splinters.
3. Refine with 120 grit. Smooth seat and backrest surfaces using 120 grit (50-pack).
4. Prep with 180 grit. Sand evenly with 180 grit (50-pack) for stain-ready surfaces.
5. Finish with 220 grit. Lightly sand with 220 grit (100-pack) for polished results.
6. Clean thoroughly. Vacuum or blow away dust, then wipe with tack cloths.
7. Apply finish. Use exterior-grade stain, paint, or sealer for long-lasting protection.

Special Cases

For hardwood benches like teak, stop at 220 grit for smoothness without reducing stain absorption. For painted benches, scuff sanding may be sufficient before repainting.

Pro Tips

• Sand with the grain to prevent scratches.
• Use sanding sponges on curved arms and detailed backs.
• Seal joints and end grains to prevent moisture penetration.
• Apply thin coats of finish for longer-lasting results.

Aftercare

• Store benches indoors during harsh winters if possible.
• Reapply protective coatings every 1–2 years.
• Clean regularly with mild soap and water to maintain appearance.

FAQs

• Do I need to sand to bare wood? Yes, for staining. For repainting, light sanding may be enough.
• Can I sand garden benches by hand? Yes—hand sanding is useful for legs and small details.
• What grit is best before sealing? 180–220 grit ensures smoothness and good finish absorption.
