ABSTRACT OF THE DISCLOSURE Decorative sheet-type covering material having a textured surface is prepared by first forming on a substrate a layer of wet polyvinyl chloride plastisol or organosol. Non-foamable chips or foamable chips containing blowing agent are embedded in the wet plastic layer which is then heated to a temperature sufficient to cure the plastic and decompose the blowing agent, to thereby foam the chips and impart a textured surface to the plastic layer. Polyvinyl chloride plastisol or organosol is the preferred plastic and a conventional topcoat or wear layer of polyvinyl chloride or polyurethane may be used. The textured surface has a height variation due to the chips of at least 4 mils.
