SurfEtch from Butterfield Color is a new water-based, biodegradable, lowodor micro-etch surface retarder. Applied to the surface of fresh concrete, SurfEtch chemically delays the set of surface mortar while allowing the underlying concrete to harden normally.
This allows time to wash the surface, removing the surface mortar and exposing sands from 1/16 inch to 1/8 inch deep. Used with natural grey, integrally colored concrete or in conjunction with stencils to create a pattern, this product creates a sand matrix finish with subtle and varying reveals of texture, pattern and color. These sand-matrix finished surfaces are attractive and slip resistant.
