Adhesives Technology Crackbond CSR Polyurethane Crack Repair, 22oz Cartridge
Crackbond CSR from Adhesives Technology is a two-component polyurethane hybrid for rapid repair of hairline cracks and spalls in concrete. Ultra-low viscosity lets the mix wet the crack face and aggregate, then the repair can take traffic in under 60 minutes at 77°F. Typical work includes industrial floors, parking structures, and bridge decks when downtime is short. Other packs of the same material are the 9oz cartridge (A9-CSRHN) and the 2 gallon kit (B2G-CSR).

Frequently Asked Questions
Can Crackbond CSR rebuild a nose joint on a parking deck?
Yes. Nose-joint repairs on parking or bridge decks are a listed Crackbond CSR use. Ultra-low viscosity wets the joint, and traffic can return in less than 60 minutes at 77F. It is still not a moving-joint filler.
Does Crackbond CSR reach 4,500 psi in one hour?
Yes. Current Crackbond CSR reaches over 4,500 psi compressive strength in one hour. That early strength, plus the under-60-minute traffic window at 77F, is why it is used on industrial floors that cannot wait on an epoxy.
Is Crackbond CSR self-leveling on a horizontal crack?
Yes. Crackbond CSR is a self-leveling, ultra-low-viscosity polyurethane hybrid. Deep penetration on a horizontal hairline is the point. Vertical or overhead paste work belongs on Crackbond Epoxy Repair Paste or Miraclebond 1310.
What jobsite temperature does current Crackbond CSR allow?
Current Crackbond CSR v101 is 0F to 110F. The 30F floor on older combined CSR-LPL sheets is LPL, not this cartridge. Stay on 0F to 110F for A22-CSRN.
Can Crackbond CSR be used neat on a hairline, then with aggregate on a spall?
Yes. Neat Crackbond CSR wets hairline cracks. Mixed with dry silica sand or pea gravel it becomes a mortar for spalls. Both uses sit on the same hybrid. Do not treat the sand mix as a different SKU.
When should a crew pick Crackbond CSR instead of Crackbond JF-82 FAST?
Pick Crackbond CSR for a dry, non-moving hairline crack or spall that needs same-shift compressive strength. Pick Crackbond JF-82 FAST when the joint must keep moving, including freezer control joints down to -40F.
