The Best Paint Gun: Our Choices
Buying and evaluation criteria for paint guns
In this section we illustrate which features can help you in your decision.
The criteria with which you can compare the paint guns with each other include:
The following paragraphs explain what you should look for in each aspect.
Reason for use
Paint guns are useful for various projects. Just as there are differences in paint for different surfaces, there are also different spray guns that are not suitable for all colours.
Basically, most products are suitable for applying paint. Only special paint guns are useful for painting walls, because wall paints are often too thick for the small nozzles of a common paint gun. Furthermore, it is possible to spray certain car parts or a bicycle with a paint gun as well.
You should compare the area to be sprayed with the nozzle of the spray gun. Smaller nozzle sizes are more suitable for smaller objects and large nozzle openings are more suitable for area-sized projects.
Most paint guns have a large container into which you can pour the paint. On average, this is between 500 and 1,000 millilitres. Alternatively, some paint guns have several small containers that hold around 20 millilitres and are suitable for using several colours at the same time.
If you use a smaller container, you should be aware that it will empty more quickly and you will have to refill it more often. Keep in mind that this depends on your reason for use.
The flow rate is relevant because it indicates how long it takes you to paint a wall, for example. The higher the number, the less work you have to do.
The flow rate is indicated differently for paint guns, either with grams per minute or with millilitres per minute. There are various sizes, from 100 millilitres per minute to over 900 grams per minute.
As a rule, you can calculate with 1 gram = 1 millilitre.
When it comes to the consistency of paint, the unit gram usually predominates by a few digits. However, you can use the rule of thumb for your purchase decision, this should be sufficient.
There is a wide range of wattages for paint guns. There are small products starting at 70 watts and others with more than 500 watts. There are also electric spray guns with 1,200 watts, but these are not necessary for normal households.
The type of air supply also depends on the power:
- Flow cup: Many paint guns have a flow cup that absorbs the paint by means of gravity. (= gravity tank)
- Suction cup: Other products have a suction cup included, which sucks the paint through a tube. However, this is only possible with low viscosity paint.
- Pressure tank: There are also spray guns in which the paint is pressurised. This allows the paint to pass through the nozzle more quickly.
The power of your paint gun should not be an exclusionary factor in your decision.
Decision: What types of paint guns are there and which is the right one for me?
If you want to buy a paint gun, there are several product groups to choose from. Two alternatives are listed below:
|High Volume - Low Pressure (HVLP) paint guns||For small areas|
|Low Volume - Low Pressure (LVLP) paint guns||For larger areas|
In the following paragraphs you will find more detailed explanations of the two products.
Guide: Frequently asked questions about paint guns answered in detail
Who is a paint gun suitable for?
Paint guns are used to spray wood, sheet metal or walls, for example. You should be aware of what kind of material you are using before you buy a paint gun.
What size paint gun should I buy?
On the other hand, there is also the alternative of painting only small areas. For this, a smaller container is suitable, which can be filled with about 200 millilitres of paint.
If you are interested in using as many colours as possible, you can invest in several containers. You can also find smaller paint guns that come with several containers of about 20 millilitres.
How much does a paint gun cost?
|Type||Reason for use||Price range|
|Small handy paint gun||For starters, smaller areas, single use||from € 20 - 50|
|Medium-sized paint gun||For walls, multiple use||€ 50 - 200|
|Large paint gun||For professionals, large areas, multiple use||from € 200|
Assuming you want to paint an entire flat using a paint gun, it is helpful to buy a smaller and cheaper version first to see how you get on with it. If you find it easy to use and you are happy with the result - then it is recommended that you invest in a larger and cheaper paint gun.
In principle, a handy paint gun is sufficient for normal household use. These are available at reasonable prices.
What alternatives are there to a paint gun?
The decision for a paint gun depends on your reason for using it. A paintbrush is a good option for painting walls, but not so much for painting a car part. You should be aware that a paint gun can usually be used for several occasions and that you do not have to dispose of it after the first use.
How do I clean a paint gun?
Be sure to wear protective clothing and a protective mask when cleaning. This can also be an advantage when using the paint gun.
Here you will find general instructions for the correct cleaning of a paint gun:
- Emptying: In the first step, you should empty the remaining paint in the container, preferably directly back into the paint pot. Then fill a nitro solution (a very diluted one is recommended) into the container and spray it onto a piece of newspaper, for example, until no more paint comes out.
- Clean up: Remove the paint needle from the tip of the spray gun and take out the paint and air nozzles. Be careful with the small parts. Clean the paint channel with a small brush and rinse it several times. Be especially careful here, otherwise the paint spray gun may no longer be in use.
- Repeat: Dry the paint channel with a soft towel or compressed air gun and repeat these procedures 3 to 5 times until no more paint is visible.
- Grease: It would be advantageous to lightly grease the paint needle, the thread and the spring.
- Assemble: When everything seems clean, put the removed parts back into the paint gun (follow the instructions of the respective product). Finally, wipe the outside with a damp cloth.
What paint should I use for a paint gun?
If you want to use sheet metal, lacquer paint is an alternative. Varnish can also be used for wood. When painting car parts, you should speak to a specialist, for example in a DIY store, who will be able to answer any further questions you may have.
