Abstract
A structure of tiles comprising numerous tiles which together form a surface covering, wherein at least part of each tile rests on a piece of underlay that lays between the surface covered and the tile. The piece of underlay had previously been fixed to the tile (having pressure-sensitive adhesive). In the embodiments of this invention, the underlay, optionally and preferably, is still attached to the tile forming an underlay which is permanently fixed to the tile. The surface covering of the present invention comprises tiles, each tile being square or rectangular, and having two opposed surfaces, wherein the tile has edges A, B, C, and D, between the surfaces and further has a coating of a pressure-sensitive adhesive and an underlay fixed to the surface having the coating of pressure-sensitive adhesive. The underlay extends beyond the surface a certain distance over adjacent edges C and D, wherein the underlay has an L-shaped release strip which can optionally be removed from the tile to expose the pressure-sensitive adhesive coating. Removal of the L-shaped strip exposes the coating on the tile in an area along adjacent edges A and B of the tile. After the removal of the L-shaped…
