System 22 Set Retarder
Coverage / Yield: Covers 100 - 500 sq. ft. per gallon, depending on application and conditions.
System 22 Retarder is a clear, waterborne cement set retarder. Misted onto the surface of concrete, stucco, cement-based mortars and patching materials, it delays the setting of cement at the surface. As cement below the surface sets, washing the retarded surface material off exposes embedded aggregates.
