Frequently Asked Questions

How quickly can I allow traffic on the repaired area?
Repairs can typically be opened to traffic in less than 60 minutes at 77°F. :contentReference[oaicite:3]{index=3}

What is the application temperature range?
CSR can be applied from 0°F to 110°F. Keep the cartridge and nozzle above 30°F for best flow. :contentReference[oaicite:4]{index=4}

Does CSR foam during cure?
The material is highly sensitive to moisture and may foam if exposed. Ensure the substrate is completely dry. :contentReference[oaicite:5]{index=5}

Is this product structural?
CSR develops strong bond and compressive strength 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 pigmented with dry powders, and cured repairs can be coated or painted. :contentReference[oaicite:7]{index=7}
