Ensure the paint gun is compatible with your air compressor’s output capacity. Check the gun’s specifications and match them with your compressor’s capabilities.

2. Regulate Air Pressure

Fine-tune your air compressor’s pressure settings to match the requirements of the paint gun. Experiment with different pressure levels to achieve the desired spray pattern and coverage.

3. Use the Right Paint

Select paint that is compatible with your chosen paint gun and air compressor setup. Thicker paints may require higher pressure settings, so be sure to check the manufacturer’s recommendations.

What Type of Air Compressor Do I Need to Paint My House?

In painting homes, electrically powered air compressors are preferred over gas-powered air compressors. There are many reasons, but mainly for safety concerns. Gas-powered air compressors are known for oil leakages which could cause dangerous situations.

Use the gas-powered air pressure if you are painting outside. Be warned, though; they are very loud. However, electrically powered air compressors also make their fair share of noise. Therefore, when selecting an air compressor to paint your home, always pay attention to capacity and PSI. In the later part of the article, we will talk about the grade and stage of the air compressor.

How to Paint Your House Using Air Compressors?

If you have been paying attention, you know you generally need two primary tools to start painting. You need an air compressor, and you need a spray painter.

Here we look at the step-by-step guide for using air compressors and spray painters at home.

1. Prepare The Area or Surface to Paint

First, you need to identify the area you want to paint. Then, put cardboard or tape on the edges, so the paint doesn’t spill out of that surface. Also, put a covering on the floor to avoid damage.

2. Prepare Your Paint and Thinner

You should know the type of paint or thinner you are using. Oil-based paints work best with air compressors, but others also serve the purpose. Decide the color of paint you want and have enough paint on hand for the task. You will not want to buy paint in the middle of the process.

3. Confirm The Air Pressure Your Spray Gun Requires

Check the level of air pressure your spray gun needs. Also, confirm that your air compressor can meet that. If the air compressor fails to produce the required pressure, the task will be a total failure.

4. Put On Safety Gears

Always make sure you have your safety kit handy. Put on gloves, goggles, masks, and overalls. The safety gear helps safeguard you against harm or dangerous situations.

5. Prime the Surface

If necessary, prime the surface. Apply with a brush or roller, then sand it. This helps the paint stick better.

6. Mix The Paint and Thinner

Follow the manufacturer’s guidelines on the ratio of paint to thinner. The amount of thinner you need will depend on the type of your paint, surface area, and air hose nozzle, but it is advisable to use at least 20%.

7. Set Up the Air Compressor

Connect the electrical cable of your air compressor to the outlet and attach its hose. Turn on the air compressor, and allow it to pressurize. Next, attach the spray gun to the hose, and make sure you set the pressure gauge on the hose to the required PSI.

8. Prime With the Spray gun

Pour a small amount of thinner into the spray gun. Aim it at the cardboard or waste bin and spray. After a few seconds, it should produce a steady flow of the paint thinner. When satisfied, empty the paint cup of the remaining thinner.

9. Pour The Mixed Paint into The Paint Cup

Fill up the paint cup with your mixed paint. Attach the paint cup to the top or bottom of the spray gun. The location depends on what type of spray gun you are using. Make sure the paint cup locks onto the spray gun.

10. Test the Spray

Aim at the same cardboard you used earlier while priming. Spray steadily, taking an up and down approach. See if you are satisfied with the result. If not, you might try remixing the paint or adjusting the air pressure. Satisfied? Then do the next step.

11. Start Painting

Imitate the same up and down movement you used earlier.

Advice and Cautions

There are a few safety tips you should adhere to while painting your home with the spray gun and air compressor.

  • Always wear safety gear—goggles, masks, gloves, and any other item you might find helpful.
  • Paint fumes and stains are harmful to inhale. They are also highly flammable. Always ensure there is proper ventilation by keeping all doors and windows open.
  • Because you will be using an electric air compressor, make sure there are no exposed wires.
  • Always make sure you are using safe paints.
  • Do not spray yourself or another person. Always aim at a surface, preferably a sturdy one.
  • Properly dispose of any waste when done with the painting.

Factors to Consider When Choosing an Air Compressor for Spray Painting

1. Capacity

The capacity of your air compressor lets you know how successful your painting will be. While checking for the capacity, consider the following:

  • PSI
  • CFM
  • HP

Spray guns usually require low pressure. However, they can produce high or low volumes.

CFM stands for cubic feet per minute. It entails the volume of air the air compressor can produce. It is probably the most important parameter when considering an air compressor. Check the spray gun to know the required CFM.

HP stands for horsepower. It is the amount of power your air compressor can produce. You want to get an air compressor that can produce enough power for your spray gun.

2. Tank size

If you are using a gas-powered air compressor, consider the tank size. You want to get something with an adequate tank size. There are different sizes ranging from 5 gallons to 50 gallons.

But what size air compressor do you need to paint a house?

The Spray painter requires a constant supply of air. This means you would need a larger tank to handle this supply. Consider getting the 50 gallons.

3. Power Source

Spray guns run on a constant air supply, meaning the energy required is high. Make sure the power source can handle this. Also, make sure it is safe to use.

4. Grade and Stages

One stage air compressors are popular but not suitable for painting. They deliver 1 CFM per HP, which is insufficient. Use stage 2 air compressors which offer at least 4 CFM per HP. For painting, get a stage 2 air compressor with at least 5 horsepower (HP) rating.


Can I use any air compressor for house painting?

No, you need an air compressor with sufficient PSI, CFM ratings and a larger tank.

What type of paint works best with an air compressor?

Latex and oil-based paints are commonly used. The choice depends on your project and personal preference.
