How do I apply the paint with a paint spray gun?

You do not need any previous painting experience to use a paint spray gun. However, in order to achieve a perfect result, we have put together a few important tips that you should pay attention to when applying your paint with a spray gun.

Did you know that you should avoid draughts when using a paint spray gun?

Due to the draught, the paint mist released by the paint spray gun can sometimes miss the direction. Instead of being carried away on the wall, it is then carried away by the draught. The fine paint dust consists of tiny particles of paint and is sometimes difficult to control.

1. Clean surfaces

  • The surface must be clean, dust-free, grease-free, dry and rust-free
  • Even the finest residues can disturb the surface appearance

2. Viscosity

  • The coating material must not be too viscous
  • adhere to the viscosity recommendation in the operating instructions

3. Temperature

  • Paint and ambient temperatures that are too cold will affect the surface and its durability

4. Stirring the paint

  • Most inks have a tendency to settle
  • Therefore, stir your paint well before use

5. Layer build-up:

  • The final coat applied to an object already coated with paint must be of the same base as the first coat

6. Test spray

  • Test your optimum amount of paint and the best spray setting on a test piece or an unseen area before you start your actual work

You can always find further tips on the use and adjustment of your paint spray gun in the corresponding instructions for use.

How do I clean a paint spray gun?

Make sure you clean your paint spray gun thoroughly after use. The paint or varnish dries in the valves just as it does on the surface, i.e. on the wood, the façade or the wall.

If you do not rinse them thoroughly after your work, the fine openings can become clogged and unusable. Since most paints are water-based nowadays, it is sufficient to rinse your equipment with water.

Decision: What types of paint spray guns are there and which one is right for you?

Basically, you can choose between three different types of paint spray guns

  • Compressed air spray gun
  • HVLP spray gun
  • Airless spray gun

All types offer different advantages as well as disadvantages, which are mainly determined by the place of use and the intended purpose.

When choosing the right paint spray gun, the specific characteristics of the individual types play an important role in the purchase decision, as the differences in the spraying process also determine the intended use.

In addition, the differences in terms of working speed, spray pattern, cleaning effort and environmental friendliness also play important decision-making factors.

In the following section, we introduce the three different paint spray guns and present their advantages and disadvantages in use. We will also show you which paint spray gun is best suited for you.

How does a compressed air spray gun work and what are its advantages and disadvantages?

With a compressed air spray gun, the material to be applied is atomised by the air stream coming out of the nozzle and reaches the object to be coated through the air.

The paint is either added through suction or flow cups or fed from a paint pressure vessel with the help of a pump.

The high degree of atomisation produces a very good spray pattern, which, however, also leads to a heavier spray mist.

The compressed air spray gun is an easy-to-use spraying system, inexpensive and also ideal for small quantities of paint and surfaces.

As a compensation, the area output is significantly lower, as only about 30% of the paint is actually applied.

Advantages
  • Cost-effective
  • Easy to use
  • Ideal for small areas
Disadvantages
  • Low area output
  • More overspray

How does an HVLP spray gun work and what are its advantages and disadvantages?

The HLVP (High Volume Low Pressure) spray gun has an air inlet pressure that is many times lower, which makes it possible to achieve a coarser atomisation.

This can have the effect of significantly reducing the spray mist. The air is supplied by a turbine or a compressor.

The HLVP technology has a very high material transfer rate of 80%, requires less energy and also ensures lower disposal costs due to the reduced mist formation.

A disadvantage is the coarse atomisation and the associated slow processing speed.

Advantages
  • Less misting
  • Less energy consumption
  • Lower disposal costs
Disadvantages
  • Coarse atomisation
  • Slow speed

How does an airless spray gun work and what are its advantages and disadvantages?

The airless spray gun uses hydraulic pressure instead of air pressure to apply the paint.

For this purpose, a high-pressure pump is used, which forces the paint through a high-pressure hose into a specially shaped spray nozzle, causing an airless atomisation to spread the paint over the surface.

Thanks to the high speed, the airless spray gun also enables a very good surface quality. In addition, the airless spray gun is environmentally friendly, offers a high area output, a fast working speed and low mist formation.

Disadvantages are the high purchase costs, the high wear, the lack of regulation of the application quantity and a high cleaning effort.

Advantages
  • Easy handling
  • Little spray mist
  • High area output
  • Environmentally friendly
Disadvantages
  • High wear
  • Much cleaning effort
  • High acquisition costs

Buying criteria: You can use these factors to compare and evaluate paint spray guns

You don't know which paint spray gun is right for you? The following article shows you which features you can use to compare and evaluate paint spray systems.

Features of paint spray guns:

  • Container volume
  • Consumption
  • Weight / including shoulder strap
  • Areas of application

The following paragraphs will help you to decide which features of paint spray guns are relevant to you in order to make your purchase decision easier.

Tank volume

When buying a paint spray gun, you should pay attention to a suitable container volume. Especially if you want to paint larger areas or a long fence, it is tedious to fill up the tank of your device every few minutes.

There are paint spray guns with different sized tanks. Some spray guns even have two tanks, so you can switch smoothly when two people are working on a project.

Consumption

If you choose a paint spray gun, you should make sure that your device does not consume too much paint, because then the painting will usually be more expensive than with paint spray systems that only consume a few litres per minute.

Weight / shoulder strap included

Another feature you should look for when buying a paint spray gun is the weight of the device. There are paint sprayers that are so heavy that they have castors and stand on the floor.

However, there are also devices that are somewhat smaller. With these, it is important that they are not too heavy so that your work is not too strenuous.

Some paint guns are therefore equipped with a shoulder strap to make the weight easier.

Range of application

Paint spray guns are suitable for different applications. Some can be used for varnish and glaze work as well as for painting walls, others are only suitable for projects with varnishes and glazes.

Facts worth knowing about paint spray guns

How does a paint spray gun work and how is it constructed?

A paint spray gun is a tool for applying varnishes and emulsion paints. The paint is atomised with the help of compressed air or a compressor and applied to the surface to be coated.

Did you know that the invention of the paint spray gun goes back to an invention by an American doctor?

The aim of the invention by the American doctor Allen de Vilbiss was actually the atomisation of medicines in the throat. In 1907, his son developed an atomiser for paints based on this invention. The paint spray gun replaced time-consuming painting with a brush and thus created the prerequisite for the industrial mass painting of cars.

Compared to a conventional paint brush or paint roller, a paint spray gun can increase the effectiveness. The atomisation of the paint produces a much better surface quality.

The paint can be fed into the paint spray system without pressure or with pressure, depending on the device. The simplest feed system is the flow cup, which is located above the gun. The material is conveyed to the gun by gravity.

Spray guns with a suction cup are similarly constructed. With this system, the paint is sucked out of the container with the help of a tube. It is important to ensure that the material to be applied is not too thick in the cup.

You should wear protective goggles when working so that no paint accidentally gets into your eyes.
