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.
A method for coating tile having an exposed decorative surface subject to wear including high areas subject to greater than average wear and low areas subject to less than average wear comprising the steps of:
A coated tile comprising a base layer having a decorative exposed surface having high areas and low areas defining said exposed surface, and disposed upon said exposed surface of said base layer a coating of protective material which has an average thickness on the high areas of the surface of said base layer which is greater than the average thickness on the low areas of said surface.
Apparatus for applying a protective coating onto tiles having pre-formed front, back, and side edges and an exposed surface subject to wear, said apparatus comprising:
