Answer
Use a consistent final grit, usually 180 or 220, and remove all dust before staining.
Why it happens
Uneven sanding, leftover dust, or inconsistent wood absorption can affect stain appearance.
Recommended grit
Prepare evenly with 180 or 220 depending on wood and stain instructions.
Wet or dry
Dry.
Success check
The wood has consistent prep before stain is applied.
What to do
- Sand the whole area evenly.
- Use the same final grit across the surface.
- Remove dust completely.
- Follow the stain maker's prep instructions.
Avoid: Do not spot-sand only one area with a different final grit.
