JF-75 is a self-leveling, 100% solids, aromatic two- component polyurea joint filler. JF-75 is designed for 15-25% movement of an installed joint width. A minimum of 28 days is recommended for concrete to effectively cure prior to installing joint filler. JF-75 can be used to fill interior random cracks, control joints or new construction joints on horizontal concrete surfaces.
