Prohard

PROHARD is a water-based, lithium silicate densifier designed to harden cementitious based surfaces and natural stone materials creating a dense, hard surface that enhances gloss and appearance. It is a non-film-forming, penetrating hardener that reacts chemically with concrete and calcium carbonate to form a solid, durable structure. This treatment increases abrasion resistance, reduces dusting and liquid penetration, and improves surface reflectivity especially when used on polished concrete, natural stone, limestone, agglomerates, and terrazzo.
