PRODUCT DESCRIPTION
SEALTIGHT is not a surface coating, but a penetrating colourless, inorganic transparent liquid designed to permanently waterproof, insulate, and harden masonry, concrete, plaster, render, and natural stone. It is a non-toxic, non-caustic, non-flammable, environmentally friendly formulation that preserves and strengthens construction materials.
Once applied, SEALTIGHT penetrates the surface and reacts chemically to bind all component parts of the masonry into a dense solid mass. This reaction neutralizes free lime and alkalis, effectively waterproofing and sealing the substrate. The result is a surface resistant to acid, oil, fuel, and grease—providing long-term protection against dusting, cracking, and seepage.
SEALTIGHT causes permanent solidification of masonry and concrete components into a single waterproof mass. Increasing density and wear resistance extends the lifespan of structures, prevents fretting, and eliminates seepage without forming a surface film.
