Frequently Asked Questions

How soon can I reopen a repaired area to traffic?
Typical repairs can be opened to traffic in less than 60 minutes at 77°F. :contentReference[oaicite:3]{index=3}

What temperatures can I apply CSR in?
The recommended application range is 0°F to 110°F. Keep cartridges and nozzle above 30°F for best flow. :contentReference[oaicite:4]{index=4}

Will CSR foam or expand?
The product is highly sensitive to moisture and may foam if exposed. Ensure the substrate is completely dry before application. :contentReference[oaicite:5]{index=5}

Is CSR structural?
CSR provides high early compressive strength and strong bond for static cracks and spalls. It is not intended for cracks subject to movement. :contentReference[oaicite:6]{index=6}

Can I color match the repair?
Yes. CSR may be used with powder pigments, and cured repairs can be coated or painted if desired. :contentReference[oaicite:7]{index=7}
