ElastiPoxy Joint & Crack Filler Kit (2-qts.) – Floor-To-Wall Joint Sealant, Cracks in Concrete Blocks, Expansion Joints, Spalled Concrete Description
ElastiPoxy Joint & Crack Filler Kit is a unique, state-of-the-art joint sealant and crack filler for concrete, concrete blocks, and masonry. A two-component FLEXIBLE epoxy. No polymer additives, 100% solids, ZERO VOCs. Low viscosity, self-leveling epoxy for filling joints, cracks, and spalls in slabs. Impact-resistant. Virtually indestructible under high water pressure or heavy traffic. Good chemical and water resistance. When mixed with sand, provides a strong, rigid filler for filling cracks or defects in masonry walls. Suitable for both contractors and homeowners. OLD WAYS AT FIXING CRACKS – Hydraulic cement is waterproof but does not bond well to concrete. Thatâs why it needs an inverted V-groove. It is also very rigid and does not move with the concrete. Polyurethane caulk is both waterproof and flexible. It bonds well to the surface of dry concrete but wicking water and efflorescence gradually weaken the bond. It has no strength and easily separates due to water pressure. KIT CONTENTS: 1 can of Base Resin (A), 1 can of Epoxy Hardener (B), 2 measuring cups, 2 mixer attachments. You will need a plastic container for mixing and a low-speed drill for the mixers. If needed, DRY construction or play sand. A small plastic watering can or cup with a spout for pouring pure epoxy into joints and cracks in floors or a small trowel for applying the epoxy-sand mix. APPEARANCE: Gray. You can mix in color pigment or use colored sand to match the surface color. The filler is partially paintable. When using pure epoxy, it is best to roughen up the surface first with a grinder. COVERAGE: Based on a routed out crack 1/4′ wide by 1/2′ deep and using pure epoxy, the smaller kit will fill approximately 75 linear feet. The larger kit provides four times more volume, 300 linear ft. Using the smaller 2-qts. kit and 4:1 sand to epoxy ratio, you will need approximately 20 lbs. of dry sand and the mixture will fill about 375 ft. of cracks Â¼â wide and Â½â deep.
