Zusammenfassung:A method for producing an aqueous composition comprising a condensate based on silicon compounds, involving the steps of i) introducing at least one polymeric rheology control agent into water; ii) adding at least one acidic catalyst; iii) adding at least one silicon compound of general formula (I) RnSiX4-n in which the radicals X are the same or different and stand for hydrolysable groups or hydroxyl groups, the radicals R are the same or different and stand for non-hydrolysable groups, and n is 0, 1, 2, or 3; and iv) performing a hydrolysis reaction of at least part of the silicon compounds of general formula (I) added in step iii). The present invention further relates to a composition that can be obtained by means of the method according to the invention.
