Abstract
An apparatus adapted to mix in a mixing chamber within the apparatus a waterless paint concentrate maintained in a reservoir within the apparatus. The concentrate is stored in the reservoir in a concentration unsuitable for application to a paintable surface. The concentrate is mixed with water received into the mixing chamber under external waterline pressure forming a paint suitable for application to a paintable surface. The paint is then discharged from the apparatus through a spray nozzle. Mixing occurs in the apparatus concurrently with discharge through the nozzle as water flows through the apparatus. The apparatus as largely a container of waterless paint concentrate with a simple mix and discharge spray head attached is disposable after consumption of the concentrate without need for cleaning.
