SWS Sealant is a high performance, 100% silicone sealant, designed to counter water and air intrusion in a variety of new and remedial applications.

SWS sealant can be used in place of organic sealants for expansion joints, window perimeters, curtainwall frames, and more. It is also effective for sealing pre-cast or site-cast concrete and tilt-up concrete joints.

Securely bonding without a primer to many substrates and finishes, SWS can be used to seal glass, polycarbonate, vinyl, plastics, wood, painted and anodized aluminum, brick, terracotta, ceramic and porcelain materials, concrete, and natural stones.
