Frequently Asked Questions

Q: Can I stamp an entire patio with one mat?

A: It’s not recommended. We suggest using at least 3–5 rigid mats to properly cover the area and maintain speed. Add a flex mat for border work.

Q: Are these suitable for overlays?

A: Yes, the SM 3001 is one of the most popular choices for stamped concrete overlays, especially with systems like SureStamp.␦
