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. For over 50 years, DOWSIL™ 790 silicone building sealant has been the standard for weather sealing 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 % 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.
