DOWSIL™ 790 Silicone Building Sealant

A one-part silicone formulation that cures in the presence of atmospheric moisture to produce a durable, fire-resistant, flexible and ultra-low-modulus silicone rubber building joint seal.

Simply the best-performing weatherseal for stone, concrete and masonry construction

For over 50 years, DOWSIL™ 790 Silicone Building Sealant has been the standard for weathersealing performance in new construction and renovation applications around the world, especially on stone and masonry surfaces. A neutral-cure, one-part sealant that quickly cures to a durable, flexible seal, its excellent movement capabilities (+100/-50 percent of the original joint width) make it ideal for sealing expansion and control joints, precast concrete panels and seismic joints, and EIFS joints. The wide range of colors available makes it easy to match your project.
