METHOD FOR MANUFACTURING A HYDROPHOBIC ELEMENT
20220161466 · 2022-05-26 ·

A method of manufacturing an embossed hydrophobic covering element for construction or decoration for protecting the surface from humidity or inclement weather. This method includes preparing a mixture of water and at least one organic material in a tank in which the organic material is insoluble in water, stirring the mixture so as to disperse the organic material in suspension in water, molding the prepared and stored mixture by immersing a forming mold under vacuum inside the tank in order to form a molded element, drying and densifying the molded element under vacuum so as to obtained a dried and densified element, and fully impregnating the dried and densified element in the binder so as to form the hydrophobic covering element. The binder is of an organic material. The organic material originates from a sustainably renewable resource.
