Answer
For rough garage epoxy spots, use 120 or 180 to level, then 220 before recoating.
Why it happens
Raised epoxy defects need leveling before recoating or topcoat blending.
Recommended grit
Use 120 or 180 for raised rough spots, then 220 for smoother prep.
Wet or dry
Dry with dust control.
Success check
The rough spot is level and clean before the next coating step.
What to do
- Confirm the epoxy is fully cured.
