BoatLIFE Silicone Rubber Sealant Cartridge - Black [1152]

This is an all - purpose 100% marine silicone sealant cartridge in black. It's non - corrosive, non - yellowing, and mildew resistant with a low odor. It becomes tack - free in 30 minutes or less and fully cures in 24 hours. You can use it above or below the waterline. It won't shrink, crack, or dry out. It offers superior flexibility and adhesion to fiberglass, plastic, metal, and wood. Even after years of exposure, it retains flexibility and tensile strength. Its acid - free cure ensures it won't corrode metal.

Using this silicone rubber sealant is easy. First, make sure the surface you're applying it to is clean and dry. Cut the tip of the cartridge at the desired angle and size, then use a caulking gun to apply the sealant evenly. You can smooth it out with a tool or your finger within 30 minutes as it's tack - free during this time. For full curing, wait 24 hours. You can use it both above and below the waterline, but avoid using it on wet surfaces. When storing, keep it in a cool and dry place. If you notice any debris on the sealant over time, you can gently clean it with a mild soap and water solution. This will help it maintain its performance and appearance for years.
