Frequently Asked Questions

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

A: It is not recommended. We suggest using at least 3–5 Rigid Stamp Mats to properly cover the area and maintain installation speed. Add a Flex Stamp Mat for borders, edges, and detailed areas.

Q: Are these suitable for overlays?

A: Yes. SM 3001 Stamp Mats can be used for stamped concrete overlays, including applications with systems such as SureStamp.
