How to Sand Wooden Fence Panels for Outdoor Refinishing (60–220 Grit)

Wooden fences endure constant exposure to sun, rain, and temperature changes. Over time, finishes peel, wood fibers raise, and surfaces become rough. Sanding is the first step to restore fences before staining, sealing, or painting.

Why Sand Fence Panels?

Sanding removes weathered layers, splinters, and old coatings. It ensures new finishes penetrate or adhere properly, extending the lifespan of your fence.

Tools You’ll Need

• Orbital sander for large flat panels
• Sanding sponges for edges and posts
• Wet/dry sandpaper sheets (60–220 grit)
• Vacuum or brush for dust removal
• Mask, goggles, gloves

Recommended Grit Sequence

• 60 grit: Removing peeling paint or rough, weathered wood.
• 100 grit: General smoothing after coarse sanding.
• 150 grit: Preparing surfaces for stain or sealer.
• 220 grit: Final sanding for a cleaner finish.

Step-by-Step Process

1. Inspect the fence. Replace broken boards or fasten loose nails.
2. Start with 60 grit. Use 60 grit (25-pack) to strip weathered surfaces.
3. Refine with 100 grit. Smooth boards using 100 grit (100-pack).
4. Prep with 150 grit. Use 150 grit (25-pack) for stain-ready wood.
5. Finish with 220 grit. Sand lightly with 220 grit (50-pack) before applying finishes.
6. Clean thoroughly. Brush or vacuum away sanding dust.
7. Apply finish. Stain, paint, or seal with exterior-grade products.

Special Cases

For pressure-treated wood, let it fully dry before sanding and finishing. For older fences, start with coarse grits to remove gray, weathered layers.

Pro Tips

• Sand with the grain to prevent scratches.
• Work in dry weather for best results.
• Apply multiple thin coats of finish for long-lasting protection.
• Seal cut ends of boards to prevent moisture damage.

Aftercare

• Inspect fences annually for peeling or wear.
• Reapply stain or sealer every 2–3 years.
• Wash fences with mild soap and water to prevent buildup.

FAQs

• Do I need to sand to bare wood? Yes, for staining. For repainting, scuff sanding is usually enough.
• Can I sand fences by hand? Yes—hand sanding works for small areas, but machines save time for large panels.
• What grit is best before staining? 100–150 grit provides good absorption and smoothness.
