Wear eye protection, rubber gloves, and a dust mask when using DRYLOK® Fast Plug®. The area to be patched should be cleaned thoroughly by wire-brushing, scraping or any other effective process*. Back chisel out the area to be patched to the shape of an inverted “V” (the point at the surface). This allows the patch to expand and lock into the surface. Wet the area prior to patching to help DRYLOK® Fast Plug® cure properly.
Both DRYLOK® Fast Plug® and water for mixing should be at room temperature. Mix 3 parts DRYLOK® Fast Plug® and 1 part water thoroughly until you achieve a putty or heavy troweling consistency. This mixture will set in 3 – 5 minutes. The use of colder water will retard the setting time. Mix only enough for immediate use due to the quick setting time. DRYLOK® Fast Plug® cannot be reworked once it has set. In cold weather, use warm (90°F) water for mixing; also, soak surface with warm water before application. Mix only enough for use in 3 minutes. Discard all leftover mixed patching material prior to starting a new batch. Leftover patching material will chemically react with new material in the mixing receptacle.
