Concrete Surface Retarders

When it comes to exposed aggregate or decorative concrete work, getting the surface just right makes all the difference. That’s where our surface retarders come in. Designed with the needs of architects, engineers, and contractors in mind, these products help you achieve consistent, professional finishes without the guesswork. Backed by decades of experience in the field, W. R. MEADOWS surface retarders are easy to use and built to perform—so you can focus on creating work that stands out.

W. R. MEADOWS’ surface retarders are spray-applied, water-soluble products designed to slow the set of surface mortar in concrete to expose the aggregate. These products temporarily halt the set of Portland cement at the surface while the concrete below the surface cures normally. Our surface retarders may also be used to produce an architectural finish on concrete slabs.
