Abstract
A method of molding a hardened glazed surface on a building block where the block is provided with a slot in the surface to be coated includes inserting a boundary edge member through the slot after the block is placed in a mold containing the coating composition; the boundary edge member conforms closely to the shape of the slot; the molding composition is cured with the boundary edge member in place and the boundary edge member is subsequently removed by forcing the member into the slot, that is away from the surface on which the composition has been molded.
