ABSTRACT:
An apparatus for evenly coating back surfaces of building tiles and the like with mortar. It comprises a doctor blade, rails which support and guide tiles for movement below the doctor blade with said back surfaces of the tiles facing generally upwardly. The apparatus is adapted for receiving and retaining a supply of mortar on said back surfaces of the tiles adjacent one side of the blade. The blade is positioned a preselected distance above said back surfaces of the tiles whereby as the tiles are urged under the blade said back surfaces thereof are completely coated with mortar and excess mortar is scraped from the tiles with the mortar remaining on said back surfaces being of a substantially uniform thickness. In the method of coating back surfaces of tiles with mortar, tiles are placed on the rails with the back surfaces facing generally upwardly. A supply of mortar is placed on at least one of the back surfaces adjacent the blade. The tiles are then urged under the blade with the back surfaces spaced a generally uniform distance below the blade whereby as the tiles are urged under the blade the back surfaces thereof are completely coated with mortar and excess mortar is scraped from the tiles with the mortar remaining on the back surfaces being of a substantially uniform thickness.
