How to Sand a Wooden Fence Before Staining: Even Color & Better Protection (60–220 Grit Guide)

Sanding a wooden fence before staining not only improves its appearance but also helps the stain penetrate evenly for long-lasting protection. Whether you’re restoring an older fence or prepping new wood, the right sanding process ensures professional results.

Why Sand a Fence Before Staining?

Outdoor fences face constant exposure to the elements, which can raise the grain, cause splintering, and leave weathered surfaces. Sanding smooths rough fibers, removes dirt and old finishes, and opens the pores of the wood for better stain absorption.

Tools & Materials

• Orbital or belt sander
• Hand sanding block for tight spots
• Vacuum or outdoor blower
• Wet/dry sandpaper sheets
• Dust mask, safety glasses, gloves

Recommended Grit Sequence

• 60 grit: Removing heavy weathering and old finish.
• 120 grit: Smoothing after coarse sanding.
• 220 grit: Final prep before staining.

Step-by-Step: Sanding a Wooden Fence

1. Clear the work area. Move any objects away from the fence and cover nearby plants.
2. Coarse sanding. Use 60 grit (25-pack) to strip weathered fibers and remove old coatings.
3. Smooth the surface. Switch to 120 grit (50-pack) for a more refined texture.
4. Final sanding. Lightly sand with 220 grit (100-pack) to prepare for stain application.
5. Clean thoroughly. Use a blower or vacuum to remove dust, then wipe with a damp cloth.
6. Apply stain. Follow the stain manufacturer’s directions for best results.

Special Cases

For cedar or redwood fences, avoid overly coarse grits to prevent surface gouging—start with 120 grit instead.

Pro Tips

• Sand with the grain to minimize visible scratches.
• Replace sandpaper as soon as it clogs for consistent results.
• Work in sections to maintain even sanding and staining.

Aftercare

• Reapply stain every 2–3 years to maintain protection.
• Inspect annually for damage and spot-sand as needed.

FAQs

• Can I use a power washer instead of sanding? Power washing can clean the surface but won’t smooth it—sanding is still necessary for best results.
• Do I need to sand a new fence? Yes—light sanding removes mill glaze and improves stain penetration.
