Dynatred is a chemically-curing, double-part, cold-applied elastomeric sealant with the effectiveness of self leveling, traffic-grade sealants and the versatility of a non-sag material. Once full cure has been established (7 days), Dynatred has exceptional resistance to water submersion. Its wide color range makes it an ideal sealant for decorative flooring, patios and pedestrian malls as well. For heavy pedestrian traffic areas subject to high heal exposure where joints exceed 3/8" in width, use Pecora Dynaflex.
