VersaFlex SL/88 is a self-leveling, 100% solids, two component, rapid curing polyurea semi rigid joint filler. SL/88 may be applied in temperatures down to -40°F and is designed with a semi-low range adhesion strength similar to High Shore “A” polyurea and epoxy joint fillers, which provides characteristics for separation during the concrete shrinkage process. SL/88 provides additional protection from spalling of joint edges/shoulders where heavy, hard wheel dollies and fork lift traffic are required. Ideal for industrial and warehouse applications, as well as restoration and repairs construction and contraction joints. Recommended time of concrete cure is a minimum of 28 days prior to installing joint filler or joint sealants.
