Can I use air compressor to paint walls?

What type of air compressor do I need for painting?

We'll discuss psi below, but a high-volume, low-pressure (HVLP) compressor is usually sufficient to complete an auto paint job. Look for two-stage compressors that deliver close to 20 CFM. Air pressure: As mentioned above, pressure (psi) is less important in an air compressor for painting cars than CFM is.

What size air compressor do I need to run 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.

How big of a compressor do I need to paint?

That being said, most air compressors with an air tank capacity of 30 gallons and up can usually handle painting a car. If you're painting a classic full-size car or want to play it safe, a tank of 60 gallons or more should be enough to coat the vehicle in a single pass.

When spraying base coat you want to spray at about 26-29 PSI. They way you read this is at your gun, trigger pulled air flowing through and your dial reading 26 psi. When spraying clear coat I like to up the pressure 2-3 psi for a little more atomization and better flow out.

What causes orange peel in paint?

Orange peel is typically the result of improper painting technique. It is caused by the quick evaporation of thinner, incorrect spray gun setup (e.g., low air pressure or incorrect nozzle), spraying the paint at an angle other than perpendicular or applying excessive paint.
