SIKA Sikaflex-291 LOT Black, All-Purpose Marine Adhesive & Sealant, Elastic & Non-Corrosive – 10.1 fl. oz – Ideal for Wood, Fiberglass, Metal, Fresh & Saltwater Applications

If you need a marine-grade sealant that creates a strong, secure bond with a wide array of surfaces commonly found in marine applications, Sikaflex-291 LOT’s black sealant is the ideal choice. It’s specially designed for use where a long working time is needed, and cooler temperatures can extend the curing period. The typical skinning period is four hours, after which it can be painted for a more professional finish. Sikaflex-291 LOT is a self-leveling marine grade sealant, so you won’t need to tool it down for an even surface. 10.1 fl. oz. cartridges fit conveniently on a variety of piston guns.
