4034 Fast 15 Minute Ultra Low Viscosity Concrete Crack Repair
4034 is a very rapid setting, high strength polyurea concrete repair polymer for high traffic concrete floor areas such as busy loading docks that need repair but can’t afford to be out of service long.
The 4034 with its ultra low viscosity (18-20 cps), self leveling formula will nano-lock to the concrete and completely fill deep cracks, holes and spalls of all sizes quickly with back-in-service times of only 10-15 minutes. The 4034 becomes hard enough in that time to allow use of an industrial grinder to smooth out the repair to become even with the floor surface.
The 4034 is effective in the worst of repair situations including deeply spalled, damaged or cracked concrete surfaces and broken control joint walls. Concrete can be repaired in extremely cold conditions down to -20°F (-26°C) for bridges, parking decks, warehouse floors, cold storage facilities, basement & garage floors. It can be used as a grout, mixing with sand 2:1 (2 parts sand to 1 part 4034) or the 4034 can be poured into sand pre-positioned in the repair area. Use of sand increases durability and improves chip resistance of repair and makes for a lower cost project. See this Project Example.
4034 Polyurea Concrete Repair is on the Costco master specs in CSI Division 3 ( 03317, 03320, 03930 ) for both new construction and maintenance concrete repair projects. Available in 2 gallon and 10 gallon kits.
For small project repairs requiring the convenience of <5 dual cartridge cartridge kits, see our E443 Quick Fix Repair cartridges.
4034 is now available in a New NO ODOR formula and for small projects and easy application in dual cartridge kits (21 oz or 600 ml total product in one cartridge kit – requires use of Twin Cartridge Guns to apply). Available in case quantities of 12 dual cartridge kits (contains total 2 gallons product) as well as 2 gallon and 10 gallon kits.
