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 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.

Do you have to thin paint for airless sprayer?

Latex paints They’re extremely viscous, so whenever you spray them with a handheld, HVLP, or small airless sprayer, you need to thin them down. … That’s true when you’re using anything other than a big airless unit. If you’re using a handheld or HVLP system, you’re probably going to have to use as much as 20-30% water.

Can you use a HVLP gun with an air compressor?

DIY and professional work can be carried out using the HVLP (high volume low pressure) spray guns. Therefore, it’s important when trying to get a flawless finish, that the compressor can deliver both psi (pounds per square inch) and cfm (cubic feet per minute) required by the spray gun.

How much psi do I need 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 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.

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

A gun that uses 15 CFM of air doesn’t need a compressor that will produce that much air as long as you have a tank large enough to hold enough reserve air to get you around the car. I usually recommend that you use a compressor that has a minimum of 60 gallon tank and produces around 13 CFM.

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.

How many CFM does a HVLP gun need?

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. Or, this one, requires 10-14 CFM.

What is the difference between HVLP and LVLP spray gun?

With the HVLP spray guns, you will have a high volume and low-pressure tool which means that it will require a good air compressor to function efficiently. … Most LVLP spray guns, on the other hand, will come at between 10 to 25 PSI and can work with as little as 5 CFM.

How big of an air compressor do I need to run air tools?

Air tools made for general use with portable air compressors typically require 0 to 5 cubic feet per minute (cfm) at 70 to 90 pounds per square inch (psi), whereas with larger tools connected to stationary systems, the requirements usually exceed 10 cfm at 100 to 120 psi.

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.

How many CFM do I need for a paint gun?

12 CFMMost paint guns are rated with a suggest CFM that they operate best at. Many guns (high end professional guns especially) are “air hogs” and require in excess of 12 CFM! This means you need a compressor that can steadily output well over 12 CFM to be able to handle those paint guns.

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

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.

Can you spray paint with a 50 Litre compressor?

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. When these three factors are considered when buying an air compressor for your paint sprayer, you’ll definitely make the right choice.
