Dicor 451BSG RV Gunnable Butyl Rubber Caulk Sealant

This single-component, solvent-release Butyl Sealant is engineered for creating watertight seals between overlapping substrates and joints. The sealant is easy to apply and manipulate with strong adhesion to a diverse range of clean surfaces including TPO, EPDM, PVC, glass, metals, and various plastics. Its design focuses on delivering a dependable primary seal that combats weather elements, thus preventing shrinkage and cracking effectively.

The tube’s gunnable property enhances precision and control during application, which substantially reduces mess and waste compared to tape. This method ensures a more uniform and consistent bead of sealant, leading to a seamless and more aesthetically pleasing finish. Additionally, the caulking tube design allows for easier storage and less deterioration over time, making it a more practical choice for both professional installers and DIY enthusiasts. The contained environment of the tube also helps in preserving the sealant’s properties by minimizing exposure to air and moisture.

Thoroughly clean and dry all surfaces prior to application to ensure optimal adhesion. The product should be applied at room temperature using a standard caulking gun, with the sealant extruded in a steady bead at a 45-degree angle. The approximate coverage per tube varies based on the bead size: a 3/8” bead covers about 11 linear feet, while a 1/4" bead extends to approximately 24 feet. This variable coverage allows you to tailor the application according to specific needs, making it versatile across various projects. Proper tooling and support of the joined surfaces are essential during the initial eight hours of curing to achieve the best results.
