The SmartFloor 3-Step Recovery System restores previously polished concrete floors in three steps. With Ameripolish’s SmartFloor Refinement System Abrasives and SR2 sealer, the process can be run wet so facilities can remain open during the day while floors are refreshed overnight. The SR2 penetrating stain-resistant sealer is also used in the system. The sealer is formulated to protect polished concrete flooring from oil, water-based stains or acidic etching agents like vinegar.
