Coatings fail when the concrete profile is wrong. A disciplined cup-wheel grit sequence builds the CSP you need.
Surface prep is not “grind until it looks rough.” Protec Tools cup wheels are graded so contractors can move from coating removal to final profile without burning the paste.
Coarse First
Start coarse to strip weak laitance or old film. Keep the grinder flat and moving; dwelling digs valleys that coatings telegraph.
Step Down Grits
Each finer grit removes the scratches of the last. Skipping steps leaves deep tracks that need more resin later.
- Pair dry grinding with HEPA extraction.
- Vacuum between grits—dust acts like rogue abrasive.
- Check CSP with replica putty when specs demand it.
- Replace loaded wheels; glazed cups polish instead of cut.
