Concrete Surface Retarder

Formula S for Exposed Aggregate Surfaces

CONCRETE SURFACE RETARDER S is a neutral, sprayable liquid for application to freshly placed horizontal concrete surfaces. The chemical formulation retards, but does not “kill” the set of the mortar at the surface of concrete. When the underlying concrete has hardened, the retarded mortar surface can be flushed off with a stream of water and/or removed by scrubbing with a stiff brush. Since this compound does not “kill” the set, if it is left on the concrete or unintentionally splashed on other fresh concrete, it will permit the concrete to eventually attain a set and achieve full strength.

• Safe to use - easy to apply
• Works quickly and effectively
• Provides up to 1/4” (6 mm) depth retardation
• Reduces cost of mechanically preparing surfaces for waterproofing, stucco or plaster application
• Etch depth can be adjusted as desired

• Creation of exposed aggregate surfaces
• Decorative sidewalks and walkways
• Slip-resistant surfaces
• Formulation for horizontal surfaces

• Fully complies with CRD C 621, Corps of Engineers Specification for Non-Shrink Grout
• Fully complies with ASTM C1107, Standard Specification for Packaged Dry, Hydraulic-Cement Grout
• Canadian MTQ

CONCRETE SURFACE RETARDER S is packaged in 55 gal (208 L) drums, 5 gal (18.9 L) pails, and 1 gal (3.8 L) jugs (6 jugs per case).
