Whatever the job at hand, Sika has the answer:



Sikaflex 291i - Sealing

Sikaflex 291i is a non-sag, one component polyurethane adhesive/sealant specifically developed for the marine market where structural strength is not critical.
It is suitable for making elastic, vibration-resistant joint seals, and can also be used for a variety of interior and exterior sealing applications.  Sikaflex-291i bonds extremely well to the materials commonly used in marine construction like wood, metals, metal primers and paint coatings (2 component systems), ceramic materials and plastics (GRP, etc.).  Sikaflex-291i must not be used to seal plastics that are prone to stress cracking (e.g. Perspex).
