A mortar extrusion gun includes a refillable and cleanable mortar supply tube possessing a first end terminating in a forwardly and radially inwardly extending flange surrounding a mortar ejection aperture and a second opposite open end. A conical spout includes a tip provided with a mortar outlet aperture and a base possessing a mortar inlet aperture surrounded by a radially outwardly extending flange. Preferably, a set of spouts possessing various different dimensions are provided for selective use under different working conditions. In an assembled condition, the spout is inserted through the supply tube and ejection aperture such that the inwardly and outwardly extending flanges abut in sealing relation, supporting the spout at the first end of the supply tube. After the supply tube is filled with mortar, a packing disk is inserted into the open end of the supply tube, and the supply tube and spout assembly is inserted into a slightly modified conventional caulking gun. Various disclosed embodiments of the packing disk possess different profile configurations and may include pressure relief vent apertures or cracks to diminish separation of water from the mortar within the supply tube and resultant clogging of the gun. Various mortar compositions suitable for pressure application and dependent upon mortar joint width are disclosed. The mortar extrusion gun is intended for use in precisely, completely, and rapidly applying mortar to joints during construction and repair of masonry structures.
