KWIK-FLEX is a unique and complete expansion joint and concrete crack repair material designed for use in low temperature areas or anywhere a quick set is desired. KWIK-FLEX cures to a high strength, resilient, and long lasting seal in just 60 minutes. KWIK-FLEX can be applied under low temperature conditions without the usual need of heat lamps or propane torches. KWIK-FLEX remains serviceable to -60°F. KWIK-FLEX may also be used for slip joints or as a crack filler.

Surface Preparation

Sawcut must be clean and free of any film, dust, grease, and oil. Foreign matter should be blown out using oil free compressed air.

Mixing Directions

For a level loop: Pour a quantity (half a gallon is recommended) of the liquid into a clean container (plastic is preferable). Gradually add the powder (approximately 7.5 lbs.) to the liquid, stirring constantly until a uniform consistency is achieved (similar to pancake batter).

For a loop on a grade: Follow the same directions as above except add slightly more powder to make a stiffer mix to prevent the sealant from flowing out the bottom of the sawcut.

Do not mix more than can be used within the pot life of the material.

When applying KWIK-FLEX, allow material to flow slowly into the loop sawcut and self- level. KWIK-FLEX may be applied to damp surfaces as well as surfaces below freezing.


Keep away from heat and open flame. Avoid prolonged contact with skin and breathing of vapor. USE WITH ADEQUATE VENTILATION. KEEP OUT OF REACH OF CHILDREN.
