Answer
For masonry paint edges, use 80 or 120 to feather, then 180 for smoother blending.
Why it happens
Loose or thick coating edges need blending so the repair does not leave ridges.
Recommended grit
Use 80 or 120 for thick edges, then 180 for smoother blending.
Wet or dry
Dry with dust control.
Success check
The paint edge is blended and no loose coating remains.
What to do
- Remove loose coating first.
- Feather thick paint edges with 80 or 120.
- Refine with 180 where smoother blending is needed.
- Clean dust before recoating.
Avoid: Do not coat over raised loose paint edges.
