A method for extruding and depositing a slurry or mortar onto a selected work surface uses a mortar gun assembly with a chamber for receiving mortar from a remote supply hopper and an extruder configured to selectively apply a bead or ribbon of mortar of selected thickness onto the work surface. The mortar gun assembly provides mortar from the hopper under pressure and the user selectively applies mortar by controlling a rotating port valve between the hopper and the mortar gun chamber. The rotating port valve provides a rest state in which the mortar is not sent to the mortar gun, but is instead re-circulated by the pump back to the hopper so un-dispensed mortar is kept moving and cannot dry or set.
