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, marble, natural stone, limestone, agglomerates, and terrazzo.
Method of use :
The floor must be clean and dry. Spray the product on the surface to be treated with a a low pressure pump or pour directly on the floor and then spread immediately with a mop or a cloth. Keep the floor wet without dry parts for 10-15 minutes. Let it dry. After applying It is possible to polish the floor using a buffing machine equipped with an abrasive disc. The surface is walkable after 24 hours.
Coverage:
Polished concrete, limestone and terrazzo: 8/15 m² *
(*) depending on the number of coats applied and porosity of the surface.
