CrackBond JF - 311 Fills Interior Control Joints

CRACKBOND JF-311 is used to fill interior control joints or new construction saw joints on horizontal concrete surfaces. It is a two-component rapid curing 1:1 ratio polyuria joint filler designed for industrial floor applications and freezer applications involving medium to heavy duty traffic. It is self-leveling, 100% solid and flexible, allowing 10-15% movement of installed joint width. CRACKBOND JF-311 can be used in exterior applications when minimal joint movement from thermal cycling will occur.
