Pentra-Sil (IH) Concrete Surface Hardener is an economical cost-effective treatment formulated for architectural concrete and terrazzo surfaces to rapidly produce a harder surface that is easy to grind and polish. Its deep penetrating, non-soluble characteristics provide longer life and higher reflectivity, helping reduce floor maintenance cost. The environmentally friendly treatment reduces alkalinity (efflorescence), improves overall abrasion resistance and reduces dusting. Use during the production (Grinding and Polishing) of concrete or terrazzo surfaces. It is designed to enhance the process, making it easier to re-profile as well as reduce costly wear and damage to diamond abrasives.
