A portable and reusable liquid spray apparatus, the spray apparatus configured to spray a liquid onto any surface. The apparatus has a spray housing which has a liquid chamber within. The liquid chamber having an opening into which a liquid may be poured and retained within the chamber. A propellant housing configured to engage the spray housing and form a first seal with the spray housing which precludes spillage of the liquid. The propellant housing holds a propellant having a pressure above atmospheric pressure. The propellant housing forms a second seal with the spray housing which precludes leakage of the propellant into the atmosphere. The spray housing also has a passage to supply the propellant into the liquid chamber. The spray housing includes a spray valve and a spray nozzle. The spray valve is configured for releasing the liquid from the apparatus thru the spray nozzle when the valve is actuated. Liquid to be sprayed is poured into the liquid chamber and the propellant housing is engaged with the spray housing. When the spray valve is actuated, the propellant forces the liquid thru the spray nozzle and out of the apparatus.
