Abstract: A time and labour saving multiple coating system for porous substrates which involves the application of a mono or poly isocyanate catalysed UV curable acrylate composition in such circumstances as to penetrate at least part of the surface of the substrate, at least a partial surface curing of the applied composition prior to any substantial degree of self curing, and thereafter applying (whether subsequent to any sanding or not) a further surfacing composition which preferably also is an acrylate composition that is both self curing and UV curable.

Abstract: An apparatus for embossing panels used in building utilises low wattage blowers to heat a zone upstream of the embossing site. Embossing is carried out by feeding a panel through the nip of an embossing wheel and an anvil roller. A track is rolled into the hard panel surface and various decorative effects are achieved by using side by side arrangements of wheels. The tendency to panel splitting is reduced by the provision of hot localised zones. The apparatus is sufficiently wide to receive the panel in both axes.
