Low Hardness Joint Filler for Light Traffic Concrete Floors
Low hardness joint filler EUCO QWIKjoint UVR 65 is engineered for use in retail, residential, and commercial concrete floors that experience foot and cart traffic rather than forklifts or heavy vehicles. Its lower shore hardness reduces the chance of cracking and splitting when joints are filled before full slab shrinkage has occurred. Designed for early-age floors, this UV-stable filler cures fast, shaves clean in under an hour, and resists fading from sunlight exposure.
