Airless Paint Spray Safely

Airless spray painting would be among the most popular methods used by professional painting contractors these days. Unlike conventional compressed air spray painting an airless spray gun has no compressed air involved in the atomisation of paint. A small airless spray tip restricts the flow of paint from the airless spray pump and as this high pressure flow of paint passes through the airless spray tip the paint is atomised into spray as the stream of paint strikes the atmosphere.

Airless Spray Tip Tailing

Tailing when spraying with an airless paint sprayer is a phenomena where two distinct heavier lines of paint appear on either edge of the paint spray pattern. Inside these heavier edge lines there may be no paint or very little paint before the spray pattern reappears and often becomes heavier towards the center.

Tailing with airless paint sprayers can be the result of several different factors or a combination of factors.


Airless Spray Tip Data

Airless spray tips are ususally numbered in thousands of an inch with a single digit in front indicating the angle the tip is cut at which determines the paint spray pattern width.

An airless spray painting tip (nozzle) is one of the most important parts of an airless spray paint machine. The airless spray tip determines the amount of flow, the level of paint atomisation and the spray paint fan width that a airless spray paint pattern will be.


Cleaning Your Airless Sprayer

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.
