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.


The 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. This tough, super thick waterproof glue is formulated for extra heavy-duty applications.
