Spall TX3 is a rapid set, high strength low viscosity polyurethane repair material. This two component, 1:1 system is designed to repair damaged joints, cracks, spalls and other concrete surface defects. Spall TX3 has additional working time when compared to TX, which makes it well suited as a pre polish filler. Spall TX3 can be hand mixed and troweled across concrete floors suffering from pinholes, pop outs and other defects. It can also be mixed with sand and cement to create a repair mortar material. Spall TX3 is low viscosity, 100% solids and VOC free.
