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.
What does 10 psi at the air cap mean?
HVLP air caps are typically rated for a maximum gun inlet pressure to achieve 10 psi at the air cap. For example if 50 psi inlet achieves 10 psi measured at the air cap, then an inlet pressure of 60 psi would exceed 10 psi at the air cap.
Why is 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.
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.
Can you spray house paint with HVLP gun?
Spraying any clear finish or paint with an hvlp or cup gun can be a little tricky, but with practice using this type of paint spaying equipment will become easy. A HVLP system is great for spraying a variety of house paints, primers and clear wood finishes.
How can you tell the difference between HVLP and conventional spray guns?
The high pressures of conventional spray guns turn paint into a finely atomized mist, giving you a thinner, finer application. HVLP spray guns produce a thicker coat due to their lower pressure, producing large droplets.
What is the best PSI to spray clear 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.
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.
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 causes orange peel when spray painting?
Orange peel is typically the result of improper painting technique, and is caused by the quick evaporation of thinner, incorrect spray gun setup (e.g., low air pressure or incorrect nozzle), spraying the paint at an angle other than perpendicular, or applying excessive paint.
How do I get a smooth finish with a paint sprayer?
Just wait till the paint is dry and lightly sand it with a fine grit sanding block to smooth it over. Paint over it again and you should be good to go!Feb 5, 2019.
How big of an air compressor do I need for a LVLP spray gun?
What Size Air Compressor Do I Need for a Spray Gun? Sprayer CFMs DeVilbiss 12-13 Iwata LVLP 16 TCP Global Kit 3.5-7.1.
Can you spray paint with a 6 gallon air compressor?
Can You Paint With A 6 Gallon Air Compressor? Spraying with a compressor can last up to 29 hours and has a capacity of 7 to 29 gallons. It is not recommended to use a compressor for spray that lasts for more than one to six hours. There is probably enough air in the air compressor to paint a car all the time.
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 much psi do I need to run a paint gun?
How Much Air Pressure Does A Paint Gun Need? Most people say that 10-15 psi when the trigger is pulled for a base coat is the ideal setting for their guns. When spraying base coat and clear coat with low volume low pressure spray guns, I spray at about 17 psi.
Do you have to thin paint for a HVLP sprayer?
Quality latex paint is significantly thicker than traditional finishes and must be thinned before it is useful as a spray finish. Insufficient thinning results in the paint coming out of the spray gun in unsightly blobs or not at all. Thin the paint with water and mix well before spraying.
Is HVLP better than airless?
HVLPs are more fine production, not high production.” Unlike airless spray guns, HVLP guns have a second control knob that regulates air flow, giving the user more control over the fan size. There is less overspray, making HVLPs a good choice when working with expensive paint.
Can you paint walls with HVLP?
Best Indoor HVLP Applications for Fine Finishes For fine-finish painting, HVLP paint sprayers include are the best choice for the following indoor applications: Interior Walls.
