The DOWSIL Contractors Weatherproofing Sealant (CWS) Limestone 20oz Sausage is a professional-grade, one-part silicone sealant designed for superior flexibility, durability, and weather resistance. Engineered to cure upon exposure to atmospheric moisture, this medium modulus sealant is ideal for creating long-lasting, watertight joints in both new construction and renovation projects.

Developed for dynamically moving joints, DOWSIL CWS provides outstanding unprimed adhesion to most nonporous substrates including glass, aluminum, metal, and painted surfaces. Its balanced adhesive strength and high recovery rate make it the go-to solution for high-performance perimeter caulking and joint sealing in challenging environments. It remains flexible and easily gunnable in all weather conditions, reducing labor time and increasing application efficiency.

Typical applications include: expansion and control joints, tilt-up and concrete panel joints, curtain wall joints, EIFS cladding, and perimeter caulking of windows, doors, and frames. With a ±25% to ±40% movement capability and excellent weather and UV resistance, it’s built to last—even in the toughest climates.
