<p>Said compositions comprise an aqueous solution of fluorhydric acid (0.5-6 %) and a fluorinated non-ionic surfactant (0.01-0.1 %). The impregnation of a mineral surface which contains silicon with one of said compositions provides for the formation of microscopic cavities in the treated surface, thereby improving the adherence of said surfaces in wet conditions, making them anti-slippery. Said compositions are useful to produce anti-slipping pavings and floorings.</p> |
