Abstract
A method and apparatus for applying mortar to the underside of a building block to be laid so that the mortar to be applied is automatically conveyed upwardly from a mortar supply container into a mortaring region where it is applied to the underside of the building block. The mortar can be sprayed onto the building block or applied thereto by a rotating coating roller, thereby automating the application of mortar and also reducing the consumption thereof.
