METHOD OF PRODUCING A PRODUCT FOR WATER-REPELLENT TREATMENT AND IMPREGNATION, AND PRODUCT AND METHOD FOR WATERPROOFING AND IMPREGNATING A SURFACE OF A BUILDING MATERIAL

摘要

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.
