How much air pressure do I need to spray paint a car?
Spray Gun Air Pressure Required To Spray Paint a Car. When spraying clear coat I like to up the pressure 2-3 psi for a little more atomization and better flow out. Setting the air pressure to about 28-29 PSI for clear will ensure you having great flow out. Most HVLP spray guns will use 10-14 scfm at 40 psi.
What is the working pressure of a spray paint gun?
The PNTgreen medium spray paint gun states that it requires a working pressure of between 20-70 PSI. Finally, the Astro pneumatic tool spray gun states that the operating pressure is 50-60 PSI. Note: it is important to not exceed the maximum operating pressure or operate on pressure too low, to ensure you get professional spray painting results.

When spraying clear coat I like to up the pressure 2-3 psi for a little more atomization and better flow out. Setting the air pressure to about 28-29 PSI for clear will ensure you having great flow out. Most HVLP spray guns will use 10-14 scfm at 40 psi.
What psi should I Set my HVLP spray gun?
Setting the air pressure to about 28-29 PSI for clear will ensure you having great flow out. Most HVLP spray guns will use 10-14 scfm at 40 psi. This is volume of air pressure per cubic foot. 10-15 psi when trigger is pulled for base coat is what most say to set your gun at.
How many psi should a paint sprayer have?
What is the best air pressure for spray painting?

What size air compressor do I need for a paint sprayer?
For small projects or single panels, your Air Compressor should be rated at 100% of the CFM required by your paint gun. If you're spraying a whole car, you'll want 150-200%. For example: A 15-20 CFM air compressor is a good match for a 10 CFM paint gun.
What pressure should I set my paint gun at?
We recommend painting between 25-30 psi while the trigger is pulled. You may see some paint tech sheets which refer to a painting air pressure of 8-10. Don't set the spray gun to those as this measurement is referring to the air cap pressure right where the paint comes out.

How much pressure does a HVLP gun need?
HVLP, or High-Volume/Low Pressure, uses a high volume of air (typically between 15-26 CFM) delivered at low pressure (10 PSI or less at the air cap) to atomize paint into a soft, low-velocity pattern of particles. In most cases, less than 10 psi is needed in order to atomize.
What PSI should I use to spray primer?
You want to set it with the trigger pulled. To begin, set it at 50 psi. Close the air volume control knob (usually located beside where the air hose enters the gun) and with the trigger pulled, open it to the point where the air volume starts to stay the same, and then stop.
Do you need 2 coats with paint sprayer?
If application is done via brush and roller, two coats are absolutely required to build up the correct mil thickness. So if you're receiving an estimate from someone and they're telling you they are doing two coats, ask them if they're brushing and rolling the whole house.

What PSI do you need for a spray gun?
You can enjoy a consistent and great flow out by setting the PSI between 15 and 29. Some HVLP spray guns require 10-14 SCFM at 40PSI, which indicates the volume of air pressure requirements per cubic foot.
What does horsepower mean in spray paint?
Horsepower. Next up, we have horsepower, which in simple words, refers to the amount of work that an air compressor can do. It is important to remember here that a higher horsepower rating does not indicate a better or more suitable compressor for your spray paint gun. It is more about how much it can deliver.

You need something brawny, like a 2-stage compressor that gives you at least 16-20 cubic feet/minute (CFM). This is the most important thing when it comes to following the basic recommendations for spray painting.
Can you pick up a compressor for a spray gun?
Because you know that the requirement for the volume of air is high, you cannot just pick up any compressor. The CFM should be in accordance with the CFM requirement of your spray gun. After determining this, make sure you pick an air compressor that produces more volume than the CFM of the spray gun.
How much pressure does an airless paint sprayer pump?
Airless paint sprayers pump paint at a really high pressure (sometimes as much as 3,000 psi) through a hose and out of a small hole at the tip of the spray gun. The tip breaks up the paint evenly into a fan-shaped spray pattern of tiny droplets.

How much air does a HVLP sprayer use?
HVLP spray guns use a high volume of air (between 15-26 cfm) at low pressure (around 10 psi or less) to atomize your paint into a soft, low-velocity pattern of particles.
Why do spray guns have gravity feed?
Gravity feed spray guns are named as such because the paint feed reservoir rests above the sprayer and aids in pressure distribution. They work best when it comes to painting a car, and they yield a really fine finish.
What is the best tool to use to paint?
Brushes and rollers often get the job done, but in my opinion a paint sprayer is the ultimate tool of choice when it comes to painting like a pro.

What happens if you run a spray gun off a compressor?
If you run your spray gun off a compressor, you know you have an infinite range of pressure you can use. Too little pressure, however, and you don’t get the best atomization — you get orange peel. Too much pressure, and you waste material because of excessive bounce-back.
What happens when you reach a pressure that doesn't widen the pattern from the previous and doesn't make
When you reach a pressure that doesn’t widen the pattern from the previous and doesn’t make the dots smaller, you’ve gone too far. You have achieved the best atomization, but you’re now wasting material because more than necessary is bouncing off the target.

Do HVLP sprayers waste paint?
HVLP spray guns waste very little paint – they’re roughly equivalent to your conventional brush or roller.

Can you spray paint with a HVLP?
My Response: The answer is yes, of course you can, but you may not be happy with the result. A HVLP paint sprayer uses low pressure air, and it has a minimum compressed air supply flow rate at that low pressure to operate properly, and that is the info that you have not supplied.
