The invention relates to the production and use of a water-repellent and impregnating product for surfaces of building materials. In order to be able to waterproof and impregnate building material surfaces in a relatively simple, economical and yet very reliable and durable manner, a coating product is proposed which is produced from two aqueous solutions and forms an aqueous solution product which contains silicon, calcium and sodium ions, wherein the capacity for dissolving the calcium oxide is increased by a dissolving agent added to the water and the finished product, after application and drying on the building material surface, forms a glass-like surface film.
L'invention concerne la production et l'utilisation d'un produit d'imprégnation hydrofuge pour les surfaces de matériaux de construction. Pour l'imperméabilisation et l'imprégnation desdites surfaces, de manière relativement simple, économique mais aussi très fiable et durable, le produit de revêtement proposé est obtenu à partir de deux solutions aqueuses, ce qui donne un produit en solution aqueuse renfermant des ions silicium, calcium et sodium. La capacité de dissolution de l'oxyde de calcium est accrue par adjonction d'un agent dissolveur à l'eau. Après application et séchage sur une surface de matériau de construction, le produit fini se présente sous la forme d'un film de surface vitreux.
