DESCRIPTION
DRYLOK EXTREME Latex Base Masonry Waterproofer is the Next Generation in waterproof coatings. Ideal for interior, exterior, above or below grade masonry walls, basement walls, retaining walls, foundations, landscape walls, cinder blocks, concrete blocks, bare concrete swimming pools, stucco and brick. Flexible Encapsulated Polymers are used for the ultimate in waterproof protection.
Specially formulated to resist mildew growth on the paint film. Certified to stop 12 psi, that’s greater than a wall of water 26 feet high!. Tested to ASTM D-7088 Resistance to Hydrostatic Pressure and ASTM D-6904 Resistance to Wind Driven Rain. Reduces radon gas penetration.

SURFACE PREP
May be applied on slightly damp surfaces, but best results are obtained when applied over dry surfaces. Wait for a dry (rain-free) period. Surface 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, or a fast setting hydraulic cement, and smooth the patch evenly with the surface around it. EFFLORESCENCE, a white, powdery, crystal-like deposit visible on the masonry surface must be removed. DRYLOK ETCH (liquid or powder formula) or Muriatic acid, used according to manufacturer’s directions, are effective efflorescence removal agents. Re-apply acid until all visible efflorescence is gone. Rinse thoroughly and allow to dry. DRYLOK Extreme may be applied over previous coatings in sound condition but the warranty is void. Not formulated for horizontal surfaces subject to foot traffic.

APPLICATION
STIR THOROUGHLY BEFORE AND DURING APPLICATION. DO NOT THIN. Air and surface temperatures must be 50°F, or higher. Apply first coat with a roller (3/4” nap), DRYLOK Brush or a good quality nylon bristle brush. If rolled, back brush the first coat to fill nay pinholes in the masonry. If brushed, work the DRYLOK into the pores of the masonry, making sure to fill all pores and pinholes (see COVERAGE). Apply at least two coats. Allow to dry 3 hours between coats. The second and subsequent coats may be applied by roller, brush or spray. When painting the inside of concrete fish ponds, allow DRYLOK Extreme to dry at least one week before putting into service.
