Impregnator HD 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. This environmentally-friendly treatment reduces alkalinity (efflorescence), improves overall abrasion resistance and reduces dusting. Use Impregnatore HDS on stained concrete floors.
