Adhesives Technology Crackbond JF-82 FAST is a two-component, rapid curing, polyurea control joint filler designed for heavy duty traffic and freezer applications. Its solvent free flexible design allows for 10 - 15 % movement of installed joint width. It can be used in temperatures between -40 °F and 120 °F (-40 °C and 49 °C).
Applications Treats moving cracks Used to fill tooled interior/exterior control joints or new construction saw joints on horizontal concrete surfaces Protects joint edges from spalling due to wheeled traffic For best performance, the maximum joint width is 3/4 in. (19 mm) and joint depth should be a minimum of 3 times the width for industrial floor applications receiving heavy duty vehicle traffic Minimum depth can be reduced to 1/2 in. (13 mm) for foot traffic May be used for exterior applications when minimal joint movement from thermal cycling will occur Keeps joints free of debris and provides a continuous surface for weight loading
Excellent tensile strength with greater than 250% elongation. The repaired crack or control joint can be shaved within a minimum of 30 minutes at 75 °F (24 °C). Complies with ACI 302.1R-15 Guide to Concrete Floor and Slab Construction regarding control and construction joint fillers. Treated joints can be opened to foot and light vehicular traffic in 90 minutes at 75 °F (24 °C). Self-leveling, low viscosity system. Wide application and service temperature range, including freezer applications. Acceptable for use in USDA inspected facilities.
