Title: COVERING MATERIAL FOR FLOORING AND WALLS
Abstract:
The present invention relates to a hard, inflexible flooring material or wall covering material, such as a tile, having a top surface (10) and a bottom surface (20), wherein the bottom surface is provided with a solid, primer layer (21)which primer layer comprises about 60 wt% to 100 wt% of a hydrophobic material, and which layer is present in a thickness between 0.001 to 0.5 mm. The invention also relates to a method of adhering a tile (230) which has been provided with such a solid, primer layer (250) to a substrate, said process comprising the steps of: applying an adhesive to at least a portion of the substrate; impressing the bottom surface of the tile into the adhesive; and, allowing said adhesive to dry. Alternatively, the substrate can be provided with such primer layer(260), and an adhesive and tile can be applied on the substrate. The coated substrate thus formed employs the primer layer as a separation layer between the substrate and the tile.
