BoatLIFE Marine Silicone Rubber can be used to seal thru hulls, ports, hatches, and windows to fiberglass, wood, and metal. Marine Silicone Rubber is an all purpose, non-corrosive, non-yellowing, low-odor 100% marine high quality silicone sealant.
Boatlife Marine Silicone Rubber becomes tack free in 30 minutes or less. Properly applied, it will come to a full cure in 24 hours. Use above or below the waterline. Will not shrink, crack or dry out. Makes an ideal bedding compound above the waterline.
Specific Marine Applications for Boatlife Silicone Rubber:
Ports, windshields, cleats, chocks, thru hull fittings. Recommended for above waterline use. It adheres permanently to most marine construction materials and bonds to itself.
The surface must be dry and free from grease, oil and other contaminants. Cut back any weathered surfaces and dry rot by routing, sanding, or sawing to solid wood. We recommend a thorough washing with an oil free solvent such as BoatLIFE Life-Calk Solvent and Cleaner. No Priming is required. Painting should be accomplished prior to applying sealant.
