Method for the forming and finishing of an accessory cladding element for use in architecture and design

A method for manufacturing an accessory cladding element for use in architecture, the method comprising:

• providing at least one elastically deformable support element comprising a first outer surface, a second outer surface and a plurality of spacer elements placed between said first and second outer surfaces;
• applying at least one impermeable and removable layer onto at least a portion of the first outer surface;
• preparing a substantially fluid, water-based cement mixture, the cement mixture comprising at least cement, water and one fluidifying and/or plasticizing additive;
• introducing said substantially fluid cement mixture into the support element to which the at least one impermeable and removable layer was applied to obtain a cement-based composite structure in a deformable state;
• removing part of the substantially fluid cement mixture from the support element so as to eliminate excess cement mixture;
• positioning said cement-based composite structure in the deformable state in a forming device;
• keeping said cement-based composite structure in association with the forming device up to solidification thereof;
• and
• removing said at least one impermeable and removable layer from said at least one portion of the first outer surface once the cement-based composite structure has solidified.
