A method for the treatment of flexible laminar covers is described. One aspect includes selecting a low-quality material with a visible surface. A first layer of a first resin in a liquid state with a weight of a first predetermined value is deposited on the first surface. The resin is dried by applying a heat source to obtain an intermediate laminar semi-finished product, A second layer of a second resin in a liquid state with a weight of a second predetermined value is deposited on an active surface of a laminar support. The resin is dried by applying a heat source. The laminar support is coupled with the laminar semi-finished product so as to face the active surface to obtain a coupled sandwich. The sandwich is calendered by applying predetermined pressure and temperature. The sandwich is heated to a predetermined temperature so as to obtain a laminar finished product.

A method for producing a multilayer laminar product includes the operations of providing a laminar support, covering a first face of the laminar support with a first covering layer in a polymer resin and consolidating, at least partially, the covering layer. The method further envisages providing, above the first covering layer, a laminar element free of any protective film. The method further envisages pushing an embossed surface against the first covering layer with interposition of the laminar element and causing the polymerization of the first covering layer.
