Planiprep ET epoxy concrete subfloor treatment is an ultra-low-viscosity, two-component, penetrating 100%-epoxy treatment design to prepare concrete slabs for subsequent flooring installation that have been treated using Planiprep SA concrete scouring agent. Planiprep ET penetrates deeply into the prepared concrete surface, strenthening it and creating a suitable surface for direct application of all MAPEI adhesives that are approved for use on nonporous substrates. Planiprep ET must be used in a system with Planiprep SA. Used in this manner, the products system provides subfloor moisture emission control up to 12lbs. (5,44 kg) and 92% relative humidity (RH) without the need for shotblasting the concrete surface.
