HOW TO USE
UsageInterior and exterior masonry walls and foundations, Basement walls, Cinder block, brick, stucco and poured concrete walls. Do not use on floors
PrepGeneral: All surfaces must be clean, dry and free of all loose, peeling paint or contaminants. Use a hydraulic-cement patching compound on all cracks, holes and separations at joints and other areas where seepage occurs. Bare surfaces: If present, remove any white powdery residue with water and a scrub brush. Previously painted surfaces: Use a tape test to ensure adequate adhesion. Press heavy-duty tape (i.e. duct tape) at various places on the painted surface. Pull the tape quickly from the surface. If the previous paint is removed by the tape, the paint must be fully removed before using this product. Reduce seepage: Repair roof and gutter leaks, install downspout extensions and build up ground level next to the house. This will divert water away from the house, reduce hydrostatic water pressure on the walls and foundation, and lower the potential for seepage.
ApplicationMix well before and during use. Apply 2 coats with a premium-quality, long-nap roller or very stiffbrush. For first coat application only, moisten bare surfaces lightly with water. For the first coat, work the product into thesurface using a brush or roller. Spread product evenly and finish with long, even strokes in one direction. Let dry 12 hoursbefore applying the second coat. Do not apply to walls that have active water seepage at the time of application.
