<p>A method of treating the surface of a flooring material comprises moving the impact point of an energy beam, specifically a laser beam, over the surface of the material to etch a pattern in the material surface. Apparatus for carrying out the method comprises a surface for supporting the material to be treated, an energy beam, and moving means for moving the energy beam to change its impact point on the material surface. The laser may be computer controlled. The material may be treated such that it changes colour upon impact of the laser. The speed and/or intensity of the laser may be varied so as to produce tonal or texture variations in the etching. The etched areas may contain a different material.</p> |
