A hand-held spray unit includes a main body preferably having a pistol grip handle depending therefrom with a passageway having an inlet at one end and a nozzle outlet at an opposite end and a mixing chamber adjacent the outlet end with a valve to control one of the handles to control flow of a pressurized fluid. A specially-designed supply container is preferably releasably mounted on the top of the body and has a horizontally elongated tapered funnel-like profile which slopes down toward the front end thereof and extends forwardly and rearwardly of the handle to provide a balance weight of the contents of the supply container. The front of the container has an outlet communicating with the mixing chamber. A rectangular interlocking connection between the container and spray unit body provides a positive releasable interlock therebetween. A slitted nozzle and forwardly directed vent at the rear and top of the supply container avoids blow-back of the sprayed material upon the user and explosion of the container should the nozzle outlet be brought too close to the surface being sprayed or the nozzle becomes clogged.
