Three new products from Mapei offer an alternative to the labor-intensive, expensive shotblasting process when prepping a floor for remodeling. Planiprep AR (Adhesive Remover) softens and lifts any adhesive residue from the concrete subfloor; Planiprep SA (Scouring Agent) gets rid of the AR residue and etches the concrete; and Planiprep ET (Epoxy Treatment) caps the concrete, controlling moisture emission.
