5 things to consider when using an air paint sprayer

Rollers and brushes were at one time considered the best way to paint until people realized that using paint sprayers is more convenient when dealing with big objects, cars, and houses. The paint sprayers also produce quality work and save a lot of time which reduces the labor cost substantially. Generally, you could have either an airless paint sprayer or an air paint sprayer. 

Airless paint sprayers do not require compressed air since they use a supply of high-pressure fluid. Air paint sprayers, on the other hand, use compressors to provide them with air. The large volume of air is used to aerosolize the paint and push it at low air pressure to ensure the target surface gets a higher proportion of paint. Air paint sprayers are therefore considered to more environmentally friendly since they reduce material consumption, overspray, and air pollution.

Before you get painting using your new air paint sprayer, there are certain things you need to consider. You probably are not a professional and you would like to do the paint job by yourself. This article will help you understand the 5 things you need to consider when using an air paint sprayer.

1. Paint mixture

A big problem with air paint sprayers is clogging which usually happens when you do not mix the paint properly. You must mix the paint well before you start using it. The paint type you choose will generally determine the thinning process that you will use. The paint manufacturers usually include instructions on the proper way of thinning their specific product. Ensure that you follow the instructions correctly especially when it comes to oil paints since they can be a little tricky.

Also, ensure that you strain your paint to ensure you do not have to deal with clogging completely. Straining eliminates clumps and any other impurities that might lead to clogging. Most people including professionals skip the straining process to save time but this is not advisable especially when you are new to the whole painting process.

2. Adequate practice

Practice, as they say, makes perfect. Understand that you are not a professional and that you are bound to make lots of mistakes. There is absolutely nothing wrong with taking a few practice rounds before actually starting your project. Painting is considered an art and requires a little bit of practice to perfect. Take a piece of cardboard or large construction paper and test your air paint sprayer on it first until you are satisfied with the result.

Practicing will ensure that you are comfortable with the sprayer and that you don’t get halfway done only to be disappointed. Re-doing a bad paint job can be rather tedious and time-consuming especially for beginners. To avoid all the trouble of starting a new all over again, take your time and practice to perfect your skills. You could also do extensive research on the different painting techniques and how to properly integrate them to your painting technique. Practicing also helps you to properly learn how to hold the sprayer and gets you used to the weight.

3. Spraying technique

Air paint sprayers are great for big projects because they reduce overspray and have a transfer rate of roughly 90%. This means that you will cover a lot of surface with less paint used compared to the airless sprayers. Unfortunately, this also means that you should only incorporate either painting horizontally or vertically throughout the project, but never both. If you spray both vertically and horizontally when working on a project, then the job will look uneven.

 A slight texturing will happen on your project and it will look weird from different angles. It is therefore important that you decide whether you are comfortable spraying horizontally or vertically before you start painting. This will ensure you do not find yourself switching the technique when you are halfway done with the project. I find it easier to spray horizontally especially for large surfaces such as walls because you will cover the distance faster when compared to spraying vertically and it also saves more time.

4. Compressor capacity

Your air sprayer includes a guide that you should be familiar with. One of the key issues that you should be aware of is the compressor capacity and the paint viscosity recommended for your particular air paint sprayer. Your particular project might just be too big for your compressor to handle and you need to factor that when using the air paint sprayer. In such a case, you will need to do your project in stages and divide the workload accordingly.

The air paint sprayer needs air from the compressor to adequately complete the job otherwise you will end up with a poor job. Note that some compressors are big enough to complete an entire day’s job but most are not able to handle a huge workload. Having a compressor with a small capacity does not mean that you will not be able to complete large projects, all it means is that you have to properly divide the workload.

5. Paint finish

Air paint sprayers require a lot of patience when it comes to finishing. This is usually because a stream of air is pushed out during the process and this could cause the paint to have spots or bubbles. To avoid this, you need to ensure that the compressor pressure is well adjusted and that there is sufficient paint in your sprayer.

You want a good finish especially after all the hard work you have put into the project. Ensure that there is enough paint in your system throughout the entire project to ensure that you have a nice finish at the end of the job. Also, adjust the pressure according to avoid more air being pushed out to avoid bubbles when painting.


When dealing with air paint sprayers you will get a good result as long as you follow the instructions correctly. I hope this article on 5 things to consider when using an air paint sprayer will help you achieve the great paint job you deserve.
