Let’s get started.
How to paint a car with a small air compressor
Step 1: Cover your workplace.
The first thing that you need to do when you are going to be painting your car with a small air compressor is to make sure that your workspace is covered.
Why do you need to cover the workplace before painting?
This ensures that you don’t get any paint on your nice, clean floor or wall. Also, make sure there is good ventilation in the work area as some paints can be toxic if inhaled.
Step 2: Clean the car
The next step is to make sure that your car is clean. You want to get all dirt and grime off before you start painting. If there is any dirt on your car, it will show up in the paint job.
The best way to do this is by washing your car and then waxing it. This will ensure that there is no dirt or dust on your car before you start painting and help to ensure a good finish.
Step 3: Remove the parts of your car you don’t want to paint.
There are certain parts on your car that you will want to leave unpainted. Think of trim pieces and moldings that you don’t want to paint, mirrors, emblems on the hood or trunk lid, or other sections that you don’t want to paint. You will need to remove these items before painting your car.
Step 4: Use right size air compressor for painting the car
This is the most important thing before painting a car. You must use the right size and type of air compressor for your paint job. You may think that a small air compressor is good enough to paint your car, but no. Using the right size compressor is essential for getting a quality job.
If you try to paint with a too-small air compressor, it will take all day to paint and may leave a bad finish. It is also very hard on the compressor motor and could burn it out.
What size air compressor do I need for painting a car?
For painting a car with excellent finishing, your compressor should be able to produce at least 15 – 18 cfm, air pressure should be minimum of 20 – 25 psi, and the tank size should be 50 gallons or higher. This size air compressor is good for painting jobs.
Step 5: Attachments for spray guns
Once you have the right size of air compressor, now it’s time to attach the gun. This is usually fairly straightforward; connect the spray gun attachment using the hose, connectors, and regulators.
Step 6: Check the airflow
Now you should check the airflow before mixing the paint. The airflow should be between 15 to 18 cubic feet per minute(cfm). If the airflow is too low, it will take too long to paint. If you have too high of airflow, it will spray too much paint. So adjust the airflow to the right setting.
It is always advisable to check that it operates at the right pressure. Most compressors will come with an adjustable regulator, which you can use to control the pressure. You should set it between 15 to 25 psi. A tip for checking the pressure is to use an air pressure gauge, which you can get at most hardware stores.
Step 7: Mixing auto paint
The next thing that you need to do is to prepare the paint. You should always be sure to mix it well before use, as unmixed paint can cause a bad job. Mix the paint as per instruction on the label and place it in a separate container or bucket. The ratio depends on the size and type of your gun.
Step 8: Apply paint to the car with an air compressor
Now is the time to apply the paint to your car. Make sure that you spray in a nice steady motion, in one direction.
When applying the paint to your car, don’t just spray haphazardly all over the car. It is best to go in one direction, starting at one area and moving forward. Don’t try to put too much paint on at once – it will cause dripping.
Step 9: Wait and repeat
The last step in your car painting project is simply to wait and let the paint dry, then repeat. You will need to do this for about 3 coats, letting the paint dry in between each. This will give you a smooth finish and a great-looking car.
