What pressure should I set my HVLP spray 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.

What pressure do you use for a HVLP spray gun?

All HVLP spray guns should operate at air pressures between 0.1 and 10 psi (at the air nozzle) and consume air volumes of 6-30 cfm to be considered true HVLP spray guns.

How much inlet air pressure can an HVLP spray gun use?

HVLP air caps are typically rated for a maximum gun inlet pressure to achieve 10 psi at the air cap.

What PSI should my paint gun be at?

The working range is between 15 and 50 psi, with smaller patterns requiring lower pressure. No two sprayers are likely to agree on the same settings, so it's a matter of personal feel. Some typical settings: 15 to 20 psi:Airbrushing, touch-up, shading, sunbursting, and thin finish materials.

Why does my HVLP spray gun spitting?

“Spitting” happens when your paint gun's nozzle is not properly screwed into place. If your paint gun is spitting or dripping paint, it is probably because the nozzle is not screwed on tightly. If you've checked your nozzle and find that it is screwed on tightly, you may need to purchase a new nozzle altogether.

Spray Gun Air Pressure Settings

What PSI should I spray base coat?

When 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.

How many CFM does a HVLP gun need?

– An HVLP Spray Gun uses a lot of air and the more you have the better. However, you will typically always need at least 8 CFM for the lowest consuming air volume HVLP Spray Gun, we recommend a minimum of 30 CFM to prevent issues with the gun not atomizing well and changes in the fan pattern occurring.

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

HVLP guns require plenty of air, so you need to have a larger capacity compressor higher than those used for diy home works. In order to spray the full range of finishing products, however, you need at least a 21⁄2 to 3 HP compressor with a 75 liters (20 gallons) tank.

Can you paint a car with a HVLP sprayer?

Not only do HVLP guns do a better job of not spraying excess paint onto the surface of a car, but they also have better “transfer efficiency.” This term refers to the amount of paint that is shot out of the gun and that then sticks to the surface of the car.

What are the advantages of spraying with less air pressure?

Less overspray, more control:

Spraying with less air pressure also has the advantages of less overspray, less waste and greater control for the painter.

Can you spray clear coat with a 1.4 tip?

The 1.4mm tip set up is ideal for use with base coats, clear coats, single stage, primers and other light to medium and some heavier viscosity paint coating materials. The 1.4 mm is a very universal tip size.

What pressure should I spray paint a car?

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.

What size tip should I use to spray primer?

First, examine the coating that will be sprayed. Heavier coatings will require a larger orifice size than lighter ones. For example, primers are usually thicker than the accompanying paint so you should use a 1.7 or 1.8 mm tip to prime most surfaces.

What pressure do you spray 2K paint?

Step 3: Get the right spray gun with which you'll apply the 2K paint. Set it to the right pressure level(psi). Usually, it's between 27-30 psi for this kind of paint.

What psi should I spray single stage?

I like to use 26-27 psi for base coat and single stage enamel and 28-29 psi for clear coat. Sometimes, your spray gun will show that you need to set it up to 10 pounds of pressure.

Why does my clear coat orange peel?

It is primarily caused by an insufficient break up of paint particles when you spray your coating. When you spray a paint, atomization occurs. This refers to the process where the paint particles break up in to small droplets. The smaller the droplet, the smoother the paint finish will appear.

Which is better HVLP or LVLP?

HVLP guns use more CFM and will require users to size their air compressor accordingly. On the other hand, LVLP atomizes better, sprays faster and lays down a better finish while using less CFM but high air pressure.

What is the most common spray gun problem?

Problem: Dry Spray. Causes: Air pressure too high. Material not properly reduced (Suction feed). Gun tip too far from work surface.

Why does spray paint look blotchy?

They are caused by improper handling of the spray paint can or sprayer. Beginner mistakes like lingering too long on one spot, stopping your spray on the project, or being too close are all causes of that blotchy spray paint look.

Why is my paint sprayer not smooth?

Sometimes, the paint can get clogged in the nozzle which will make the paint spit out. This will not give you a smooth texture and you'll have to sand it off later. If the paint does spit, you'll most likely need to clean the nozzle or switch it out with another nozzle if you have one lying around.
