4EVERSEAL is a special formulation of minerals that penetrates, seals, hardens, and protects terrazzo, stone, brick, concrete, unglazed tile, and other mineral and masonry surfaces.
4EVERSEAL adds hardness and strength to cement, terrazzo, and other masonry and mineral surfaces (including mortar and grout joints). Literally petrifies the area directly below the surface where applied. Penetrates into pores and increases density and durability, keeping dirt and moisture on top of the surface so that they are easily wiped away. Yet it allows vapors to exit and masonry to continue normal “breathing” action. Clear, non-yellowing, entirely without odor, easy to apply without streaking, enhancing natural beauty of stone and terrazzo. Non-flammable and non-toxic. Unaffected by repeated freeze-thaw cycles. Protects against freeze-thaw contraction and expansion so that cracking of masonry is reduced.
