EXPOSED AGGREGATE RETARDER
Using water-based chemistry engineered for architecturally refined sand finishes and exposed concrete surfaces. Exposed aggregate retarder allows for a more controlled and even reveal of the desired aggregate texture.
Applied to the surface of fresh concrete, exposed aggregate retarder chemically delays the set of the surface mortar while allowing the underlying concrete to harden normally. This allows time for washing the surface, producing exposed aggregate flatwork, with subtle and varying reveals of texture and color.
