Answer
For epoxy floor flakes, knock down raised spots with 120 or 180 lightly, then clean before clear coat.
Why it happens
Loose or raised flakes need leveling so the clear coat spreads evenly.
Recommended grit
Use 120 or 180 lightly to knock down flakes, then clean before clear coat.
Wet or dry
Dry with dust control.
Success check
Raised flakes are knocked down and the surface is clean before clear coat.
What to do
- Let the flake layer cure as directed.
- Scrape loose high flakes first if needed.
- Sand lightly with 120 or 180.
- Vacuum and clean before clear topcoat.
Avoid: Do not sand so hard that the flake broadcast is removed unevenly.
