ABSTRACT:
A tile having pre-formed edges and an exposed decorative relief surface with high areas subject to greater than average wear and low areas subject to less than average wear is provided with a protective coating which is thicker on the high areas than on the low areas. The coating covers the exposed surface without covering the pre-formed edges. Such coatings are provided in high volume production apparatus by the steps of (a) providing a continuous succession of base tiles with abutting front and back edges; (b) spraying a first coating of protective material onto the exposed surface of the tile from one or more points vertically within the side edges; (c) at least partially curing the first coating; (d) applying a second coating of protective material primarily onto the high areas on the exposed surface by roller coating; and (e) curing the protective coating. In preferred embodiments, the protective coating material is cured by exposing it to ultraviolet radiation.
