Densorete-77 is a water based, environmentally friendly, penetrating sealer, densifier & crystallizer for the protection and strengthening of cementitious and marble floors prior to high gloss polishing. The active matter in Densorete-77 reacts with the calcium compounds in the marble & the by-products of cement hydration by crystallization to produce more CSH gel which densifies the concrete and decreases its porosity. More over Densorete-77 contains hydrophobic additives which act as an impregnation within the micropores to enhance the sealing and protection of the flooring against moisture related problems as well as staining. This complex system ensures the ability of high gloss polishing with good protection against moisture related problems and increasing the life span of the flooring.
