An apparatus and method for coating a substrate with plastisol and depositing pebbles into the ungelled coated plastisol is presented. A powder containing fusible particles compatible with the coated substrate and the pebbles is then deposited by at least one rotary silk-screen printing frame and thereafter a heat treatment is carried out in an oven or with infrared lamps at a temperature below the distortion temperature of the substrate in order to set the deposited materials.
