Quick Answer: What Pressure Should I Run My Spray Gun?

What pressure do you spray 2 pack paint?

27-30 psiSet it to the right pressure level(psi).

Usually, it’s between 27-30 psi for this kind of paint.

Step 4: Make a perfect blend of the 2K color, 2K reducer, and 2K hardener,as they don’t come in a pre-mixed condition.

Once done, load the sprayer with the mix..

What does 8 10 psi at the air cap mean?

When using compressed air, the lower the pressure, the smaller the volume of air available. … Air compressed to 100 pounds contains 8 times the original volume. Obviously at 10 psi to the spray gun inlet, very little volume would be available for atomization.

How big of an air compressor do I need for a HVLP spray gun?

Most hvlp guns require around 10-12 or more cfm’s. You can purchase spray guns that only require 3-6cfm’s but you can purchase a compressor for what they cost.

What is an air cap?

The air cap on the spray gun plays an important role in spray finishing as it directs air to atomize the fluid, gives the particles sufficient velocity to reach the product surface, and shapes the pattern.

How many coats of clear is too much?

We send a test card with every order, so use this not only for your color match test but to get a feel for how the clear coat sprays. Practicing on another surface before you start on the vehicle will help you avoid applying too light or too heavy of a coat. Plan for 2-3 coats.

Why does my HVLP spray gun spitting?

Spray guns spit when air is being introduced into the fluid outside of at the air cap. A loose fluid nozzle does not properly seat in the tip of the spray gun and causes air to enter the fluid supply resulting in spitting.

How much psi do I need to run a spray gun?

Air pressure affects results 15 to 20 psi:Airbrushing, touch-up, shading, sunbursting, and thin finish materials. 20 to 25 psi:Soft, velvet-like coverage, with lacquers in particular. 35 to 45 psi:Average spraying range for sealing and topcoating. 50 psi: waterbase lacquers may need this much pressure.

What PSI should my paint gun be?

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.

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 the best pressure for car painting?

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.

Do you need a regulator on spray gun?

It is a good idea to have a regulator on or close to the gun, both to mitigate any pressure drops in your system over the run of your lines, and to be able to “tune” your gun’s spray pattern based on the type and viscosity of material you are shooting.

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 does PSI at the cap mean?

That 10 psi is a MAXIMUM air pressure recommended at the air cap.
