Profile, clean, and prep concrete surfaces
Concrete blasting strips paint, sealers, and contaminants and creates the CSP profile needed for new coatings to bond. Common for garage floors, warehouse concrete, and pool resurfacing.
Concrete Surface Profile (CSP 1–9). Light coatings need CSP 2–3; heavy epoxy needs CSP 4–5. Contractor will spec per coating.
Done right, no — pool blasting is a standard step before replastering. Use a contractor with pool experience.
