PetraTec surfacing system
PetraX
Exposed aggregate, designed into the surface.
PetraX is a wet-on-wet exposed-aggregate system for decorative concrete restoration. PT380 is the white cementitious base; a selected integral color and aggregate pack are incorporated to establish the specified color and exposed-aggregate profile. The existing concrete, repair conditions, elevations, transitions, drainage, and surface preparation must be reviewed before placement. The integral color, aggregate type and gradation, distribution, exposure depth, timing, and final protection control the appearance of the completed work. CST supports customer projects with system guidance, sample or mockup work, installation planning, and ongoing technical support.
