About This Product
100% Silicone Sealant for Concrete and Masonry
GE Sealants® Concrete Silicone 2 Sealant is a professional-grade 100% silicone sealant designed for sealing concrete, mortar, brick, stone, and other common building materials. It creates a durable, flexible seal that withstands movement while providing long-term protection against weather and moisture.
Long-Lasting Weather and Mold Resistance
Built for demanding exterior conditions, the silicone formula resists UV exposure, freezing temperatures, and seasonal weather changes. It also provides mold and mildew resistance for up to 10 years, helping maintain clean, durable joints in outdoor applications.
Strong Adhesion Across Multiple Building Materials
Concrete Silicone 2 bonds to concrete, brick, stone, metal, wood, and other common construction materials without shrinking or cracking. The permanently flexible seal accommodates normal joint movement while maintaining a dependable weatherproof barrier.
Professional Performance for Exterior Sealing
