Answer
For splintered fence boards, use 80 or 120 first, then 150 before stain.
Why it happens
Weathered fence wood often has raised fibers and damaged grain that needs a coarse enough grit before stain prep.
Recommended grit
Use 80 or 120 to remove splinters, then 150 for stain prep.
Wet or dry
Dry.
Success check
The board feels safe to touch and has no raised splinters.
What to do
- Brush off loose dirt.
- Sand splintered areas with 80 or 120.
- Blend the surface with 150.
- Remove dust before stain or sealer.
Avoid: Do not use fine grit first on splintered fence boards.
