ABSTRACT OF THE DISCLOSURE Method for producing a dull, a grainy, or a sparkling surface on the depressed (mortar) areas of a chemically em- bossed foamed organic plastic sheet. The sheet is prepared conventionally except that a tacky coating is formed in the mortar areas while maintaining a state of dryness in the land areas; especially by use of a radiation-curable poly- urethane coating which is cured in the land areas by radia- tion while the mortar areas are masked. Inert particles or flakes distributed over the tacky mortar areas create the desired surface effects when the polyurethane composition in these areas is cured; which is preferably done by the heating employed in the conventional foaming operation.
