FLEX GLUE

THAT’S ALOTTA DAMAGE®.
Fix it with Flex Glue.

Product Description

FLEX GLUE® is an easy to use, super strong, waterproof adhesive with amazing instant grab and hold. Specially formulated to work on all types of surfaces and can be applied on dry or wet surfaces, even underwater! Solvent-free, paintable, and no run and drip so it can be applied overhead. Available in white and crystal clear. Available in squeeze tubes and cartridges.

Our high-tech formula for FLEX GLUE® CLEAR is the best in clear adhesives. Many other clear glues are water based or solvent based, and can shrink up to 40% at times. Unlike these other brands, FLEX GLUE® CLEAR will not shrink or crack.

Flex Glue Pro has even more instant grab! This tough, super thick waterproof glue is formulated for extra heavy duty applications. For use with a standard caulking gun (not included). Available in 9 and 10 oz cartridges.
