Abstract
The invention comprises a pneumatic gun for applying mortar in small scale applications, especially for one man operations around the home. The gun may also be used for mason contractor use. The gun uses an air supply fed by a thumb activated air nozzle that supplies air pressure to the top of a column of mortar inside a small dome shaped reservoir. A flex-type pressure release hose between the thumb trigger and the reservoir allows the pressure to be released to stop the flow of mortar upon flexing the hose.
