Flex Epoxy - Flexible Control Joint Filler



Flex-Epoxy is a 100% solids, two component, equal volume elastic type epoxy. If is a self-leveling system used for saw-cut control joints and grooves in masonry.

Basic Uses

Flex-Epoxy is recommended for use as a filter and sealer for narrow masonry control joints and grooves to prevent damage to the joint and its edges as well as promote a clean sanitary surface. Due to its tenacious bonding quality and high strength, it reinforces the joint and edges, preventing deterioration. Flex Epoxy seals and protects against water, foreign matter and corrosive elements.


Do not apply when concrete is less than 7 days old. Do not apply when temperatures is less than 50 degrees F. Flex-Epoxy is designed for areas where ultimate movement is less than 10%. Do not use in areas subject to constant immersion.

Surface Preparation

Area must be clean, sound and dry. Conventional cleaning methods used are acid etching, shot blasting or aqua-blasting. Saw-cut joints should be blown clean and dry with compressed air to remove all excess moisture and debris.
