PetraTec surfacing system

PetraStamp

Texture and pattern over existing concrete.

PetraStamp is a stampable cementitious overlay used to create imprinted texture and pattern over prepared existing concrete. The system allows a new decorative surface to be installed where removal and replacement of the slab is outside the project scope. Substrate profile, repairs, cracks, joints, elevations, drainage, and transitions must be incorporated into the installation plan. Pattern layout, stamp texture, color, release method, detailing, and final protection determine the completed appearance. CST supports customer projects with system guidance, sample or mockup work, installation planning, and ongoing technical support.
