Dow 888 is a one-part silicone sealant and can be used as the original sealant in new concrete construction or as a remedial or repair sealant in old construction. In new construction, it provides the extra insurance needed if all the “shrink” or contraction cracks do not occur during the initial “weakening”step. Because of its lowmodulus characteristics and good extension/compression recovery (+100/-50 percent of original joint width), Dow Corning 888 Silicone Joint Sealant gives outstanding performance in highway, airport and bridge joints in which high movement occurs.
Stocked in: Quart-sized caulk tubes
