What PSI should a HVLP gun be set 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.
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.
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.
Do I need a regulator on my spray gun?
It's a good idea to have a regulator on or close to the gun, to mitigate any pressure drops in your system across air lines, and to be able to tune your gun's spray pattern based on the type and viscosity of material you're shooting. ... Regulators are relatively expensive, and they mount to the hose junction of the gun.
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.
How many CFM do I need for a HVLP gun?
– 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.
What PSI should I set my air compressor?
Most air tools require between 70 and 90 PSI. Any light-to-medium-duty air compressor can easily handle 90 PSI, but you always want the compressor to supply more flow than needed. Pro Tip: Always respect a PSI rating. If you don't supply enough air volume, the tool won't operate correctly.
How does air pressure create paint problems?
This problem occurs when tiny air bubbles rise to the surface of the paint and pop, leaving craters behind. To avoid this, make certain that your spray gun is adjusted properly, use the correct air pressure setting and keep your gun an appropriate distance away from the surface.
Why does HVLP orange peel?
With the newer water-based materials orange peel is usually a result of spraying on too thick of a film. ... If the air control valve is fully open (or perhaps removed for Latex spraying) then orange peel can only be one cause – our number one factor, the material being sprayed is too thick and must be thinned.
What air pressure do you spray paint at?
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.
