DESCRIPTION
Oil Base DRYLOK Masonry Waterproofer is a ready-mixed masonry waterproofing paint specially formulated to waterproof interior, exterior, above or below grade masonry walls. Ideal for use on cinder and concrete block, poured concrete walls, stucco, brick, retaining walls, basement walls, birdbaths and fishponds. Not for use on floors.

SURFACE PREP
Masonry surfaces must be clean and free from dirt, dust, grease, oil, form release compound, frost or paint. Patch all holes or cracks with DRYLOK Fast Plug, 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. Containing synthetic rubber and Portland cement, this tough, alkali-resistant coating may be applied on slightly damp surfaces but best results are obtained when applied on dry surfaces.

APPLICATION
STIR THOROUGHLY BEFORE AND DURING APPLICATION. DO NOT THIN. Paint only when air and surface temperatures are 50°F or higher. Apply DRYLOK Masonry Waterproofer directly on bare masonry. For best waterproofing results, wait for a dry (rain-free) period before application. Apply first coat with a DRYLOK BRUSH or good quality nylon bristle or fiber brush, working the WATERPROOFER into the pores of the masonry - avoid excessive brushing (see COVERAGE). APPLY TWO COATS. Allow 12 hours drying time between coats. The second coat may be applied by brush, roller or spray.
