Costar Top 10 is a clear sodium silicate based solution which chemically reacts with soft free lime and calcium carbonate compounds in concrete to densify and create chemically resistant surfaces. It is used to cure, harden and seal fresh or hardened concrete.

Costar Top 10 is recommended for use on old and new concrete surfaces such as light industrial plants, warehouses, laundries, as well as in food storage plants and bakeries. It is also appropriate for areas with frequent foot traffic such as civic centers, sports arenas, stadiums and other commercial buildings.
