What PSI is needed for spray painting?
10-15 psi when trigger is pulled for base coat is what most say to set your gun at.
Personally I spray at about 17 psi when spraying base coat and 20-25 for clear coat using the low volume low low pressure spray guns.
The normal scfm that these guns use is 5-7 scfm cubic foot per minute.
Volume of air used at 40 PSI..
Can you spray clear coat over old clear coat?
A: Clear coat can be applied over existing clear coat, as long as it is in good condition. … Urethane clears bond to the base coat while it is still drying. Spraying clear over base after more than 24 hours is not preferred.
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.
Can you paint a car with a 20 gallon air compressor?
As a rule of thumb most air compressors with an air tank capacity of 30 gallons and up and usually handle painting a car if you match the paint gun CFM to the CFM rating of the compressor for a complete buying guide visit AirCompressorsUSA. … Most can be stored under a workbench and can paint an entire car no problem.
What is a good size air compressor for spray painting?
For most DIY and non-industrial applications, 1 to 2 HP motor is good enough with paint sprayers rated for 6 CPM and 30-40 PSI. Today, 2 HP air compressors have crept into the mainstream retail market. You should be good if your choice delivers at least 8 CFM at 40 PSI.
What PSI should I spray clear coat?
26-29 PSIWhen spraying base coat clear coat systems, you want to spray at 26-29 PSI. You measure this PSI by pulling the trigger and letting air flow through the tip of your gun with your dial or digital readout saying 26-29 PSI.
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.
What’s the best compressor for painting?

What causes orange peel HVLP?
The most common cause of orange peel is an imbalance between the viscosity of the finish and the amount of air atomizing the liquid as it exits the gun. The thicker the liquid, the more air that is required; the thinner, the less air needed. So the obvious fix is to increase the air pressure or thin the material.
What compressor do I need for spray painting?
A typical spray gun will require low pressure, and HIGH volume, FAR more than any standard compressor yields. This one, for example, requires between 0-70 PSI, but 12 CFM. 12 CFM is far more than ANY standard compressor provides, not even in bursts.
Is airless or HVLP better?
Atomized particles from an HVLP unit are smaller and more uniform than particles propelled from an airless sprayer, he says. With latex wall paint on drywall, the difference won’t matter. … But airless units are better for high-volume jobs, such as the exterior walls of a house.
Can I use my air compressor for painting?
Using an air compressor and a paint sprayer can help you cover more space at one time and can help you make sure that you get an even coat of paint on your surface.
How many layers of clear coat should I apply?
Plan for 2-3 coats. When applying multiple coats (recommended), it’s a good idea to apply the first coat lightly. Doing so helps prevent shrinkage, which causes cracks. All preceding coats should be full and wet!
What psi do you use to paint a car?
ten to 15 PSIContrary to what many believe, you don’t really need to crank the air pressure up so high to get an even coat of paint on your vehicle. You can easily get your hands on a high volume, low-pressure (HVLP) spray painter, which doesn’t need that much PSI to run. Experts recommend spraying a base coat using ten to 15 PSI.
Can you spray paint with a 50 Litre compressor?
This is why, while you can use a 6 gallon air compressor to power a nailer, you cannot use it for paint sprayer. Paint sprayers require a compressor with a large tank, preferably from 50 gallons and above, in order to be able to keep up with the spray gun.
What is a pressure feed spray gun?
More specifically pressure fed spray guns that utilize a pressure tank with dual regulators. A dual regulated pressure tank gives you precise control over pressure of fluid both to the material and to the air that breaks the material up (the atomization air).
Are Harbor Freight paint sprayers any good?
