Concrete Crack Repair – Flexible Joint & Crack Sealant
POLYFLEX is a 100% solids, two component, moisture insensitive epoxy. POLYFLEX is formulated polysulfide free to resist damage from wheeled traffic and stress vibrations. POLYFLEX is specifically designed as a filler and sealer for narrow masonry grooves and expansion joints. This self leveling, flexible epoxy exhibits tremendous adhesion to concrete which reinforces the joint thus preventing deterioration of edges. POLYFLEX can be used for saw cut control joints, grooves and masonry joints to protect against water damage, corrosive materials and dirt build-up. It provides industrial strength concrete crack repair for flooring and any other concrete surface.

Application Instructions
- Surface should be prepared by using conventional cleaning methods such as acid etching, disc grinding, sandblasting or power washing. The surface to be covered should be free of loose materials, paints, sealants or oils. Use our RESOLVE to remove oils and dirt.
- Tape both sides of joint or groove for neat application and easy removal.
- Blend 1 part A (Resin) to 1 part B (Hardener) until mixture is streak free. Maintain components above 50°F.
- Pour mixed components into joint. A second pass may be required as low viscosity materials tend to concave in the joint.
- Remove tape immediately upon completion of installation. Clean tools with our Solvent #20.
