      Marine Sealant

      When the surfaces on your deck and galley need sealing, it is not advisable to use a product from the aisles of the big box home supply retailers. For one thing, their products are not marine grade, so any repair or sealant will soon degrade making your efforts and time wasted. Come to Wholesale Marine instead. Our marine caulks and marine sealants are time-tested and guaranteed to seal out moisture and prevent corrosion.

      We offer a range of quality products from Sika, 3M, Boatlife, and Sudbury. Need to finish your chores and get out on the water? Sika’s 291 Fast Cure Caulk is a home run and is available in black or white. It dries quickly and is ideal for repairs where fast drying time is imperative. Available in a range of sizes, Boatlife’s Marine Silicone Rubber Sealant is a solid choice when repairing rubber, wood, fiberglass or metal and will remain flexible and tensile for years.
