Abstract
The present invention concerns a surface covering element comprising: a mineral substrate layer, optionally coated with a suitable primer; a decor printed onto the substrate layer, forming a decor layer; and—a transparent protection layer obtained from a curable polymer formulation. It further concerns a process for its manufacture comprising the following steps: a. providing a mineral substrate layer; b. optionally, applying a primer onto at least one surface of the mineral substrate layer; c. printing a decor onto the substrate layer; and d. coating the printed decor with a transparent protection layer obtained from a curable polymer formulation.
