Airless Spray Tip Tailing

Airless spray paint fan pattern 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 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.

Replacement Airless Spray Parts

Replacement parts and accessories for airless paint sprayers can be expensive and locating the right parts and accessories can be difficult especially if your airless machine is an older model.

Properly identifying the brand and model of your airless spray machine is the only way to begin searching for the correct parts. Occasionally parts location can be further complicated by different brand airless spray gun hand pieces or airless spray tips being fitted. Many airless paint spray units are covered in paint which can make it even harder to identify the make and model.


Piston Airless Valve Diagnosis

Diagnosing problems with airless piston pump pressure valves.

Here is a way to test your piston airless spray pump to ensure the inlet valve and outlet valves, including the relief valve are functioning correctly.

This test is much easier to do and see the results with a large longer stroking airless piston pump compared to a small short stroke fast cycling piston airless sprayer.

A small airless spray tip that slows the output of the airless piston pump will make this test easier to read.


Use Airless Spray Safely

Airless spray gun safety.

Serious injury can occur if an airless spray unit is not used correctly.

Even small handheld DIY airless spray guns reach pressures which can cause serious fluid injection injury. Never place any part of the body near nozzles or remove guards.

Always ensure that all components of your airless spray machine including airless paint spray hose, spray gun and airless spray tip are rated to a working pressure that exceeds the output of your airless spray pump.
