This is a 70mml tube of white Sikaflex®-291, which is a water resistant marine sealant/adhesive and bonds very well to metal, wood, paint & plastics (such as GRP).

Perfect for multipurpose use on boats, caravans, motorhomes as it cures on exposure to moisture in the atmosphere. Useful for interior and exterior applications, it remains elastic, which means it is vibration resistant, yet it can still be sanded down (when fully cured).

Please note that Sikaflex®-291 is not for sealing materials that are likely to suffer stress cracking, such polycarbonate or plexiglass sheets.
