Answer
After pressure washing, let the deck dry, then sand raised fibers with 80 or 120. Use 150 for smoother prep.
Why it happens
Water and pressure can raise wood fibers, especially on soft or weathered deck boards.
Recommended grit
Use 80 or 120 for raised fibers, then 150 if a smoother stain-ready surface is needed.
Wet or dry
Dry after the deck is fully dry.
Success check
The deck feels even and dry with no fuzzy raised grain before finishing.
What to do
- Let the deck dry completely.
- Sand raised fibers with 80 or 120.
- Use 150 for smoother stain prep.
- Clean dust before stain or sealer.
Avoid: Do not sand wet deck boards.
