A most common cause of airless spray gun problems and early failure are a result of incorrect cleaning and airless paint sprayer storage procedures.
When your airless paint spray job has completed the first step is to recover as much of the remaining paint that still remains in the airless spray unit. Consult your airless paint sprayer operation manual for the recommended procedure to remove any remaining paint from the airless machine and to properly flush the airless unit out.
Airless sprayers are an excellent method of applying decorative and protective paints or coatings to almost any surface quickly. Airless spray paint units when correctly setup are also capable of providing extremely high quality painted finishes.
Almost any type of paint or coating can be applied using an airless spray unit. Thin products such as stains, timber preservatives, lacquers, polyurethanes and enamels can be applied using an airless sprayer provided the correct filtration, spray tip and pressure setting is used.
