Application Instructions

Surface must be clean and free from dirt, dust, grease, oil, form release compound or paint. Patch all holes or cracks and the floor/wall joint with DRYLOK FAST PLUG® or a fast setting hydraulic cement, and smooth the patch evenly with the surface around it. Check the joint where the floor and wall meet and fill any breaks with DRYLOK FAST PLUG®.

EFFLORESCENCE, a white, powdery, crystal-like deposit visible on the masonry surface must be removed.

DRYLOK ETCH or muriatic acid, used according to manufacturer’s directions, are effective efflorescence removal agents. All masonry surfaces are subject to occurrences of efflorescence.

Old paint in poor condition must be removed by wire-brushing, sand blasting or by using other suitable means May be applied on slightly damp surfaces, but best results are obtained when applied over dry surfaces. For best waterproofing results, wait for a dry (rain-free) period.

STIR THOROUGHLY BEFORE AND DURING APPLICATION. DO NOT THIN. Paint only when air and surface temperatures are 50°F or higher. Apply Latex Base DRYLOK Masonry Waterproofer directly on bare masonry. Apply first coat with DRYLOK BRUSH or good quality nylon bristle brush working the WATERPROOFER into the pores of the masonry - avoid excessive brushing (see COVERAGE). APPLY TWO COATS. Allow to dry 3 hours between coats. The second coat may be applied by brush, roller or spray. For information on spray application, write UGL and ask for Spray Specification Sheet D-88 or visit

If leaking is still present after two coats, it indicates that pores or pin holes are still open. Paint these areas again. When painting the inside of concrete fish ponds and nonpotable water tanks, allow Latex Base DRYLOK Masonry Waterproofer to dry at least one week, fill with water. If desired, a high quality latex paint can be applied over DRYLOK after 24 hours for decorative purposes.
