Answer
For drywall texture high spots, use 180 or 220 lightly after the texture dries.
Why it happens
High spots need light knocking down without flattening the whole texture pattern.
Recommended grit
Use 180 or 220 for light texture high spots.
Wet or dry
Dry.
Success check
High spots are reduced while the texture pattern remains consistent.
What to do
- Let the texture dry fully.
- Sand only raised high spots with 180 or 220.
- Use light pressure.
- Remove dust before primer or paint.
Avoid: Do not sand the entire texture flat unless that is the intended finish.
