PROSEAL is suitable for the superficial protection of granite both for indoor and outdoor. We recommend PROSEAL on quarzitic stones and materials with different percentage of silicate and carbonate. It works very well on polished, honed, sandblast, and flamed surfaces. PROSEAL operates in the micro-porosities of materials giving a protection against stain. PROSEAL does not create superficial films, and let the material transpires. After the application a light increase of colour can be gotten that depends by the type of stone where the product is applied. Good the resistance to the outside conditions.
