Abstract: A method of making pre-grouted mosaic panels, wherein each panel (1) is formed from a plurality of mosaic tiles (2) each having a upper surface (4) and a lower surface (5), the tiles (2) being laid over a substantially horizontal support base (S) in mutually spaced positions, to define a plurality of grooves (3). The method includes a step of placing a first thermoformable polymeric sheet element (10) on the upper (4) and lower (5) surfaces of the mosaic tiles (2) and a later step of thermoforming the first sheet element (10) for the latter to at least partially fill the grooves (3) when it is thermoformed. A pre-grouted mosaic panel that can be obtained by such method.
