Abstract

The invention relates to a process for producing shaped gypsum boards, comprising the following steps: a) preparing a uniform aqueous solution containing water; at least one chloride salt, a moistening agent and one or several reinforcing materials selected from the group consisting of phosphoric acids, each of them containing one or several phosphoric acid units; salts or ions of condensated phosphates, each of them containing two or several phosphate units; and monobasic salts or univalent orthophosphate ions; b) applying the uniform aqueous solution onto the gypsum board in an amount sufficient to soften the gypsum board and to allow the gypsum board to modify its shape; c) modifying the shape of the board upon desire; d) leaving the gypsum board to dry for obtaining the shaped gypsum board, the chloride salt, the reinforcing material(s) and the moistening agent being applied onto the gypsum board in such an amount that the modified shape of the gypsum shaped board is obtained faster and the resistance thereof to permanent deformation is higher than it would have been without the application of the chloride salt, reinforcing material and moistening agent onto the gypsum board.
