SIMHARD - Polysiloxane Lithium Silicate Concrete Densifier

by Simiron

SIMHARD is a patented premium hardener, densifier, and sealer designed to penetrate and strengthen vulnerable surfaces. This infiltrating polysiloxane + lithium silicate sealer reacts with concrete to produce insoluble calcium silicate hydrate within the concrete pores.

By reducing concrete dusting, SIMHARD provides a cleaner and healthier work environment. Treated surfaces will not contribute to ASR (Alkali Silicate Reaction) and will slow down ASR within the concrete.

Using SIMHARD to densify the concrete when polishing enhances the overall appearance and gloss results. Ideal for new or existing concrete, integral color, acid stains, dyes, and dry shake hardeners.
