DRYLOK® Latex Base Masonry Waterproofer

If water is leaking through existing masonry or you need to protect new construction, our proprietary formula is GUARANTEED to stop water. Unlike ordinary paint that simply adheres to a surface and can be forced off by incoming water pressure, DRYLOK® Latex Base Masonry Waterproofer actually penetrates the pores in that surface, bonding to the masonry and creating an impenetrable barrier.

  • Preparation

    DRYLOK® Latex Base Masonry Waterproofer may be applied on a slightly damp surface, but best results are obtained when the surface is dry, clean and free of grease, oil, form release compound, and paint. Remove dust, dirt, and any loose or broken mortar with a wire brush. Old paint in poor condition should be removed by wire-brushing, sandblasting or other suitable methods*. If you see white, powdery, crystal-like deposits on the surface, they are naturally-occurring, water-soluble salt compounds in the masonry, pushed out by water intrusion. When the water evaporates, the salt residue remains. This effect is called efflorescence and, because it prevents DRYLOK® Latex Base Masonry Waterproofer from properly bonding to the surface, it must be removed. Treat it with DRYLOK® Etch®** (liquid or powder formula) or muriatic acid according to the manufacturer’s directions, rinse and allow to dry. Since efflorescence occurs naturally, we cannot warrant against it reoccurring.

    Patch all cracks and holes with DRYLOK® Fast Plug®. Wet the surface to be patched and, so DRYLOK® Latex Base Masonry Waterproofer can better anchor itself into the wall, back chisel the areas to be patched into shapes like an inverted “V”. Apply and smooth the patch so it’s even with the surface around it. As DRYLOK® Fast Plug® sets rapidly, mix only what you’ll use in 3 to 5 minutes. Also, be sure to seal the area where the floor and wall meet. Often, when concrete floors cure, they shrink and pull away from the wall, creating a space where water can enter.

  • Application

    Schedule your project when both air and surface temperatures are 50ºF or higher and, for best results, wait for a dry (rain-free) period.

    Cancer hazard: Contains Crystalline Silica, which can cause cancer***.

    Stir DRYLOK® Latex Base Masonry Waterproofer thoroughly before and during application - do not thin. Apply the first coat to bare masonry with a three-quarter-inch nap roller, a DRYLOK® Brush or a quality nylon bristle brush. If using a brush, work the DRYLOK® Latex Base Masonry Waterproofer into the pores of the masonry, making sure to fill all pores and pinholes. If using a roller, back brush the first coat to fill all pores and pinholes. Give the first coat three hours to dry, and then apply a second coat using a roller, brush or sprayer.

    Proper coverage, a minimum of 2 coats, is required to warranty waterproofing. After the second coat, carefully inspect the entire surface for pinholes. Give these areas an additional coat. If leaking is still present after two coats, it indicates that pores or pinholes are still open. Paint these areas again. When painting the inside of concrete fish ponds and non-potable water tanks, allow DRYLOK® Latex Base Masonry Waterproofer to dry at least one week, then fill with water.

  • Disposal

    Dispose of contaminated absorbent, container and unused contents in accordance with local, state and federal regulations.
