JF-90 is a self-leveling, 100% solids, semi-rigid, two component, rapid curing modified polyurea semi rigid joint filler. May be applied in temperatures down to – 40°F. Provides additional protection from spalling of joint edges/shoulders where heavy, hard wheel fork lift traffic are required. Ideal for industrial and warehouse applications where epoxy joint fillers would also be specified. Recommended time of concrete cure a minimum of 28 days prior to installing joint filler.
