Product Description
The Urethane Slab Crack Repair Kit w/ UV Stabilization provides the needed components for the repair of cracked concrete floors and slabs in areas where UV light is present. The kit includes both our CR304 Urethane Slab Repair compound and our CR305 Polyurea Crack and Joint filling compound.
CR304 Urethane Slab Repair is a specially formulated hybrid urethane that allows for repairs of cracked, honeycombed, and spalled concrete in minutes. Its very low viscosity and self leveling nature allow for deep penetration into concrete cracks for a full and complete repair. It sets very rapidly and cures in approximately 15 minutes. Repaired areas can generally be ready for regular traffic in less than one hour. Once cured, its has a tensile strength of over 4000 PSI and provides for a permanent solution with excellent strength and durability. Repaired areas will have high impact and chemical resistance. CR304 can be combined with Silica Sand for repairing larger cracks. CR304 can be used on both interior and exterior surfaces. This product is not UV stabile and cures to a tan color.
The CR305 is used as a final step in filling a repaired crack and provides UV stability for exterior applications or where UV light is present. It is a heavy duty, rapid setting Polyurea that cures to a gray hard rubber like flexible material. It allows for sealing or topping off of cracks after the CR304 is used. Its self leveling nature allows for a flat and clean finish. It sets very rapidly and cures in approximately 5 minutes. Filled or sealed areas can generally be ready for light traffic in 30 minutes and regular traffic in less than one hour. Once cured, the CR305 provides for a permanent solution with excellent strength and durability. Repaired area will have high impact and load resistance.
