PetraTec surfacing system
PetraStone
Layered color. A natural stone-inspired surface.
PetraStone is a cementitious decorative overlay installed as layered, integrally colored deposits to produce a stone-like surface. The system is intended for sound, properly prepared concrete and can be used to renew existing knockdown texture or establish a new multicolor finish. Substrate profile, repairs, transitions, drainage, and existing coatings must be evaluated before the assembly is designed. Color placement, deposit size, and application technique control visual density and movement across the finished surface. CST supports customer projects with system guidance, sample or mockup work, installation planning, and ongoing technical support.
