Abstract:
A substance for proofing a surface of solid building material against liquids and chemical and biological corrosion comprising an aqueous solution product having silicon, calcium, and sodium ions and produced from a mixture of two separately formed aqueous solutions one of which contains water, dissolved calcium oxide, and a dissolving agent which increases the solubility of the calcium oxide in the water and the other of which contains water and sodium silicate, said aqueous solution product being applicable in a wet state to said surface to form a coating on said surface which, after drying, forms a glassy film, said aqueous solution product containing the following components (in % by weight):52.5-56% water (H2O), 24-33% saccharose (C12H22O11) 1.9-2.7% calcium oxide (CaO), and 8.6-21.3&it;â€ƒ&it;%100&it;â€ƒ&it;%â€ƒsodium metasilicate pentahydrate Na2SiO35H2O).
