Sikaflex 291 LOT Long Open Time Adhesive Sealant - White - 10.1 oz

Nearly as strong as Sikaflex-291 and slightly more flexible, Sikaflex-291LOT takes longer to become tack-free, allowing for a longer working time when needed — such as for bedding-in of teak plank decking laid on top of a sub deck surface.

This is an all-purpose product used for general sealing applications such as deck hardware and equipment. It is resistant to weathering, seawater and ultra-violet radiation.
It is suitable to make elastic, vibration-resistant joint seals, and can also be used for a variety of interior sealing applications.

Sikaflex®-291 LOT bonds well to the materials commonly used in marine construction like wood, metals, metal primers and paint coatings (2-C systems), and fiberglass.
Do not use Sikaflex®-291 LOT to seal plastics that are prone to stress cracking (e.g. Plexiglass, Polycarbonate, etc.).

Sikaflex-291's permanent elasticity and medium strength, make for relatively easy disassembly, should that be necessary; use razor wire as a tool.
For similar performance with non-yellowing benefit use Skiflex-521UV (very good) or 295UV (best), but note the shorter work time.
