Abstract: A method, system and sprayer for applying adhesives, or other coatings, is disclosed herein including a positive displacement pump having an inlet connected through a dispensing nozzle to a reducible volume container. The reducible volume container may be located in a more rigid container such as a cardboard box. As the positive displacement pump is operated, a suction on the collapsible container is drawn by the positive displacement pump. The pump may pump adhesives, or any other fluid material, preferably into an attached hose and through a bayonet type spray wand. The spray wand may have a replaceable tip to alter the spray coverage and may be activated by a trigger.
