This warranty shall not apply when the waterproofer fails due to improper product application, failure to follow label directions, inadequate surface preparation, cracked structural surfaces, reoccurring efflorescence or any conditions not foreseen by UGL. There are no other warranties that extend beyond this warranty. United Gilsonite Laboratories ( UGL ®) warrants DRYLOK ® Extreme Masonry Waterproofer, when applied according to directions on a properly prepared bare masonry surface, will provide a waterproof coating for fifteen (15) years from the date of application, warranty includes subsequent owners. If leaking is still present after 2 coats, it indicates that pores or pinholes are still open. After the second coat, carefully inspect the entire surface for pinholes. Proper coverage, a minimum of 2 coats, is required to warranty waterproofing.
Give the first coat two to three hours to dry, and then apply a second coat using a roller, brush, or sprayer ( Download our Spray Specs). If using a roller, back brush the first coat to fill all pores and pinholes. If using a brush, work the DRYLOK ® Extreme Masonry Waterproofer into the pores of the masonry, making sure to fill all pores and pinholes. Apply the first coat to bare masonry with a three-quarter-inch nap roller, a DRYLOK ® Brush or a quality nylon bristle brush. Stir DRYLOK ® Extreme Masonry Waterproofer thoroughly before and during application - do not thin. Schedule your project when both air and surface temperatures are 50☏ or higher and, for best results, wait for a dry (rain-free) period. Often, when concrete floors cure, they shrink and pull away from the wall, creating a space where water can enter. Also, be sure to seal the area where the floor and wall meet. As DRYLOK® Fast Plug® sets rapidly, mix only what you’ll use in 3 – 5 minutes.
Apply and smooth the patch so it’s even with the surface around it.
Next, back chisel the areas to be patched in the shape of an inverted “V” so DRYLOK® Fast Plug® can better anchor into the wall. Patch all cracks and holes with DRYLOK® Fast Plug®. Since efflorescence occurs naturally, we cannot warrant against it reoccurring. Treat it with DRYLOK® Etch** (liquid or powder formula) or muriatic acid according to the manufacturer’s directions, rinse, and allow the surface to dry. This effect is called efflorescence and, because it prevents DRYLOK ® Extreme Masonry Waterproofer from properly bonding to the surface, it must be removed. When the water evaporates, the salt residue remains. 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. Remove dust, dirt, and any loose or broken mortar with a wire brush. Please do feel free to comment if there's something wrong, or that I missed.DRYLOK ® Extreme Concrete & 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.
