Walkthrough & quote
We visit your space, measure the concrete, assess prep needs, and lock in a fixed price — no surprises.
Surface prep
Diamond grinding, crack repair, and oil removal so the coating bonds deep and never peels.
Prime & coat
A penetrating primer plus two smooth coats of epoxy or polyaspartic, finished to a mirror shine.
Cure & inspect
