The fastest-curing, most flexible, and most UV-stable marine sealant you can squeeze out of a cartridge
TotalBoat Seal combines the best attributes of different elastomeric sealants to create one that’s stronger, adheres better, is more flexible, and has a longer shelf life. It skins over fast to prevent contamination by dirt or dust, won’t sag on vertical surfaces, and cures quickly. It’s also highly UV stable, resists staining, and can even be sanded and painted over upon full cure.
Use it for a variety of applications, including bedding hardware, sealing portholes and windshields, flush and overlapping joints, stopping leaks, and more. 10 ounce (290 ml) cartridges fit standard caulk guns, making it easy to apply a clean bead. In addition, TotalBoat Seal’s moderate bond strength allows disassembly. Compare Seal’s properties: no other sealant offers this combination of adhesion, elongation, shelf life, and strength.
