Usage

Sikaflex®-291 LOT is a multipurpose sealant for the use in marine applications where a long working time is necessary such as for bedding-in of teak plank decking laid on top of the sub deck surface. 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. Sikaflex®-291 LOT must not be used to seal plastics that are prone to stress cracking (e.g. Plexiglass, Polycarbonate, etc.). This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.
