    APPLICATION AND INSTALLATION


    PREPARATION

    Concrete must be sound, clean and free from oil, grease, wax, cement paste, dust, dirt and any other contaminants. Concrete must be at least 28 days and minimum Compressive strength 25N/mm 2 and minimum tensile strength (pull off) at 1.5 N/mm 2 . The moisture content in concrete must be lower than 6%. The substrate should not have a relative humidity more than 85% at installation period. Total enclosed grinding, high water pressure jet, or scarifying must be employed followed by vacuuming. All holes and voids must be repaired prior to installation. Seal the surface with moisture barrier or modified epoxy cement in case of surface subject to rising damp or moisture movement. Please consult Rockmax for more information.
