ABSTRACT:
A cured elastomeric film coating, on the surface of a cementitious article, prepared from the application of an aqueous dispersion of colloidal silica and an anionically stabilized hydroxylated polydiorganosiloxane is improved in water impermeability, adhesion to the surface of the article and gains abrasion resistance when the cured film coating is allowed to stand in open air for approximately four weeks prior to use.
