Frequently Asked Questions
Is Crackbond JF-82 FAST for control joints or expansion joints?
Crackbond JF-82 FAST is a polyurea control-joint filler for tooled interior/exterior control joints and new saw joints on horizontal concrete. It is not for expansion joints. Keep an expansion-joint sealant on true expansion joints.
How much joint movement can Crackbond JF-82 FAST take?
Crackbond JF-82 FAST is designed for 10 to 15 percent movement of the installed joint width. That movement band is why it is used on slightly moving cracks and control joints, not on a non-moving CSR-style hairline repair.
How soon can a Crackbond JF-82 FAST joint be shaved at 75F?
Crackbond JF-82 FAST is shave-ready in about 30 minutes at 75F. Foot and light vehicle traffic follow at about 90 minutes at 75F. Those clocks are why freezer and warehouse joints can close the same shift.
Can Crackbond JF-82 FAST be used on a freezer slab?
Yes. Crackbond JF-82 FAST is designed for heavy-duty traffic and freezer applications, with a use range from -40F to 120F. Freezer control joints are a primary listing, not an afterthought.
Does Crackbond JF-82 FAST protect joint edges from wheeled traffic?
Yes. Filling the joint with Crackbond JF-82 FAST protects joint edges from spalling under wheeled traffic. Best performance is at a maximum joint width of 3/4 in., with industrial-floor depth at least three times the width.
When should a crew pick Crackbond JF-82 FAST instead of Crackbond CSR?
Pick Crackbond JF-82 FAST when the joint must keep moving, including control joints and freezer saw cuts. Pick Crackbond CSR when the work is a dry, non-moving hairline crack or spall that needs same-shift compressive strength.
