How much pressure do I need to spray paint?
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.
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?
A general rule of thumb is: Heavy-bodied primers and primer surfacers work best when you use a nozzle size of 1.7 to 2.2. Basecoats should be sprayed with a 1.4 to 1.6 nozzle. Clearcoats should be sprayed with a 1.3 to 1.7 nozzle.
Can I spray paint with a 6 gallon compressor?
compressor is recommended for continuous spray and a 7 to 29 gal. compressor for intermittent spray, but it is not recommended for 1 to 6 gal. The air compressor will probably run all the time. I have a 13 gallon air tank and it will paint a car.
What size compressor Do I need to spray paint?
Look for a minimum of 15 psi, with some applications, such as clear coat, better-suited to 20 or 25 psi. Horsepower: For auto painting, a 10hp compressor will typically suffice. However, higher horsepower compressors may operate more efficiently, and can be used for other tasks.
Are LVLP spray guns any good?
LVLP spray guns are better than HVLP spray guns because they produce few defects. This is because air bubbles can be produced in high volume which can cause a lot of defects. The LVLP uses low pressure and a thin nozzle which allows a low volume of paint to be pushed out of the gun.
How big of an air compressor do I need for a HVLP spray gun?
I usually recommend that you use a compressor that has a minimum of 60 gallon tank and produces around 13 CFM.
What is the difference between HVLP and LVLP spray gun?
LVLP is an acronym for Low Volume Low pressure which means that it uses less air volume (5-18 CFM) then HVLP (10-25 CFM) and lower air pressure (10-30 PSI) than a typical conventional Airspray gun (35-60 PSI). LVLP guns have large air passage like the HVLP guns but the air caps have slightly smaller holes.
Can I use spray gun for primer?
It is advisable to put a small disposable one on the end of your gun. Because primer is thicker than body paint and clear coat, it is recommended you use a 1.8mm tip and air cap when applying primer. You need to re set your gun every time you use it. Now you set your pressure at the gun inlet.
What does 10 psi at the air cap mean?
It should also be pointed out that the 10 psi at the air cap is pretty much generic to all hvlp guns. That 10 psi is a MAXIMUM air pressure recommended at the air cap.
How do you thin a primer for a spray gun?
How to Thin Spray Primer
- Read the label on the can of primer and look for thinning instructions.
- Fill the spray gun partially with the undiluted primer, if the label does not specify a ratio.
- Add a small amount of clean water to water-based primer or a small amount of mineral spirits to oil-based primer.
