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. Application For active leaks (the presence of flowing water through a break in the surface): mix the appropriate amount of DRYLOK® Fast Plug®. In approximately 2 – 3 minutes, the mixture will become warm to the touch. This means it is beginning to set. At this time, force DRYLOK® Fast Plug® into the opening with the palm of your hand. Hold it in place for 3 – 5 minutes to ensure a complete set and bond sufficient enough to stop the flow of water. The patched area may be smoothed and trimmed to the surrounding area in approximately 5 minutes. DRYLOK® Fast Plug® may be painted when set with DRYLOK® Original Masonry Waterproofer , DRYLOK® Extreme Masonry Waterproofer, DRYLOK® Powdered Masonry Waterproofer or DRYLOK® Concrete Floor Paint. For Inactive Leaks, Patching, and Anchoring: thoroughly soak the area to be patched. This will prevent the surface from sucking the water out of the patching material. Apply DRYLOK® Fast Plug® with a putty knife or trowel. Use the surface to smooth the patch evenly. When anchoring, chisel or drill a hole in the masonry surface slightly larger than the item to be anchored. Make certain DRYLOK® Fast Plug® is tamped firmly into the hole and around any metal parts.
