It improves the bond of Mapei cementitious flooring systems and self-levellers, Ultratop toppings, and multilayer epoxy and polyurethane resin floors such as Mapefloor and Planitop EL. Parking decks, warehouse floors, labs, and wet or dry processing areas. Can go on damp surfaces. Sand can be broadcast into it for extra mechanical bond, and Mapei requires it, with a full sand broadcast, under Ultratop PC.
