Glue Devil General Purpose Silicone is a premium, single-component RTV (Room Temperature Vulcanizing) sealant engineered for both interior and exterior use. It cures upon exposure to atmospheric moisture to form a tough, permanently flexible, and waterproof rubber seal that won’t crack, shrink, or become brittle over time. Key Performance Features Permanently Flexible: Maintains a high degree of elasticity to accommodate thermal expansion and structural movement without losing its bond. Weather & UV Resistant: Formulated to withstand harsh sunlight, rain, and extreme temperature fluctuations, making it ideal for outdoor applications. 100% Waterproof Seal: Creates an impenetrable barrier against water and moisture, protecting joints from leaks and water damage. Superior Adhesion: Bonds powerfully to most non-porous surfaces, including glass, ceramics, fiberglass, aluminum, and painted surfaces. Ideal Applications Glazing & Windows: The primary choice for sealing glass into window frames and weatherproofing around exterior window and door casings. General DIY & Maintenance: Perfect for sealing gaps in gutters, downpipes, and skylights. Kitchen & Bathroom: Suitable for general sealing around sinks, tiles, and backsplashes (where specialized anti-fungal properties are not the primary requirement). Automotive & Marine: Useful for basic weather-stripping, sealing light assemblies, and protecting electrical connections from moisture. Product Benefits Fast Skinning Time: Forms a protective outer layer within minutes, reducing the risk of dust and debris sticking to the wet sealant. Non-Shrinking Formula: Ensures the seal remains tight and flush with the substrate even after years of exposure. Easy Application: The 280ml cartridge provides a smooth, consistent flow for professional-looking beads and joints. Pro Tip: For a professional “mirror-smooth” finish, use a masking tape on either side of the joint before applying the silicone. Tool the bead immediately with a caulking tool or a finger dipped in a mild soapy water solution, then remove the tape while the silicone is still wet.
