A fluid applicator has a fluid-containing cask within which is a displaceable piston operable in response to operation of a piston controller to dispense fluid through a dispensing valve from the cask to an applicator. A handle is removably coupled to the cask to facilitate the application of fluid to a selected site. The handle may be separated from the cask without impairing the ability of the piston to displace fluid from the cask. The valve is manually adjustable to enable a selected quantity of fluid to be dispensed cask.
