Guide to airless spray tips

November 30th, 2016

HOW DO TIPS WORK?

• An airless sprayer pumps and pressurises the paint without the use of air.

• The paint is then forced to go through the small hole of the tip under high pressure (up to 350 bar).

• This process atomises the paint in a controlled fan width and flow rate (same effect as placing your thumb on the end of a garden hose)

You can compare it to choosing the right bit for your electric drill.

There are bits designed for wood, bits for metal and bits for concrete. Each bit for each application comes in a variety of sizes. Using the wrong bit on the wrong surface does not work, and with airless tips it is very similar.

The right spray bit will help decrease overspray, provide more control and less time spent on the job.

Choosing the right spray tip will ensure the best standard of finish for the job.

CHOOSING THE RIGHT TIP

• Decreases overspray

• Provides more control

• Results in less time to spend on the job

• Less paint usage

WHY SO MANY DIFFERENT TIPS AND SIZES?

Getting the most from your spray tip depends on several factors such as the tip's fan width, hole size, the sprayer's maximum output, the type of paint being used, the substrate and the wear of the tip.

Getting the most out of your spray machine depends on several factors.

HOW TO CHOOSE THE RIGHT TIP?

The pump produces:

• Paint flow

• Paint pressure

The tip defines:

• The spraying angle

• The spraying volume

The tip size tells the pump how hard it must work in order to maintain the desired pressure.

One coat with a spray machine can equal the same as three coats with a roller.

Spray painting can allow you to complete multiple jobs in a day.

ADJUSTING TO THE RIGHT TIP

Experiencing with a few tips will help you gain experience and will help you decide what is the optimum tip for your application.

THE TWO MAIN CAUSES FOR TIP WEAR ARE:

• Working pressure at the gun.

• Abrasive material

Abrasive material such as textured paints will ravage a spray machine resulting in failure of the machine.

To explain what tip wear is and what this means to your business, think again of the similarities between spray tips and drill bits. Have you ever tried to drill into concrete using a worn out bit? If you have, then you know that it takes much longer to drill, takes much more effort and the drilled hole ends up being very unprofessional.

It is the same with continuing to spray with a worn out tip.
