Surface retarders / concrete photo engraving process

Grace Construction Products now offers a comprehensive line of products for architectural concrete, including Top-Cast surface retarders for exposed aggregate concrete and an exclusive process for photo engraved concrete. Both products were developed by Pieri SA, which Grace acquired last year.

Top-Cast is a top surface retarder designed for exposed aggregate concrete applications.

Top-Cast’s water-based, film-forming formulation employs a surface-protective polymer that eliminates the need to cover the concrete surface with plastic during the curing process.

Top-Cast is available in a range of formulations to control the depth of etch.

Grace also offers a photo engraving concrete process for reproducing images and photographs onto concrete.

Grace Construction Products ( manufactures a wide variety of concrete admixtures.
