What is an HVLP Paint Sprayer?
4 cons you need to know before buying.

What does HVLP mean?

To begin, we are going to start by answering the question, what is an HVLP paint sprayer? HVLP paint sprayers are modified based on their high-volume, low-pressure technology. While conventional paint guns use compressors in order to get high pressure to paint, HVLP spray guns use low pressure using an air regulator to control the flow rate. This helps to make your chroming job more efficient by reducing waste while you apply your spray chrome. When you use your HVLP automotive paint spray gun, you can lessen waste and reduce overspray. However, the guns do have both advantages and disadvantages over conventional guns that you should be aware of. (Read more: HTE/RP vs HVLP vs Conventional Spray Gun )

4 Advantages of HVLP spray gun

High Transfer Efficiency

HVLP (High Volume Low Pressure) spray guns are designed to maximize the transfer of paint or coating material onto the surface being sprayed. This results in less overspray and waste, making it a more efficient option.

Finer Atomization

HVLP spray guns produce smaller paint particles, resulting in a finer mist and smoother finish. This allows for better coverage and a professional-looking result.

Reduced Air Pollution

HVLP guns operate at lower air pressures compared to conventional spray guns, reducing the amount of paint mist released into the air. This makes them more environmentally friendly and compliant with air quality regulations.

Versatility

HVLP paint guns can handle a wide range of coatings, including paints, stains, lacquers, and varnishes. They are suitable for various applications, from automotive painting to furniture refinishing.

4 Disadvantages of HVLP spray gun

HVLP spray guns offer excellent transfer efficiency, produce high-quality finishes, and are environmentally friendly. However, there are also several disadvantages to using HVLP paint sprayers for your applications.

Slower Application

Compared to high-pressure spray guns, HVLP guns tend to apply coatings at a slower rate. This can be a drawback when working on large projects or when time is a constraint.

Limited Distance and Reach

HVLP paint guns may have limitations in terms of distance and reach. The lower air pressure may restrict the spray pattern and limit the gun’s effectiveness in reaching tight corners or distant areas.

Potential Clogging

HVLP spray guns are more prone to clogging, especially when working with thicker or more viscous coatings. Regular cleaning and maintenance are necessary to prevent issues with paint flow.

Cost

HVLP air spray guns typically have a higher upfront cost compared to conventional spray guns. Additionally, they may require specific equipment, such as a compressor with adequate air volume, which can add to the overall investment.

How do you use an HVLP paint sprayer?

The particular job that you will be completing is important when you are thinking about using an HVLP paint gun. If the job is very large, you might want to choose a faster gun because of the slow speeds involved with low-pressure guns. These guns use up all of the paint you pour into them. After you have filled the gun with your chrome spray paint, apply it following the steps we have outlined on our website.

When you are spraying, keep the gun no more than 8 inches from the surface, and spray back and forth using even, slow strokes. Most HVLP guns give you control over spraying by having a button that you can turn on or off to spray. You’ll also need to make certain that you have a sufficient air supply. In order to break your chrome spray into finer particles, you can add a solvent in a suitable ratio so that you have the air supply that you need at the tip of your gun. You can adjust the pressure by triggering the knob. (Read more: How to Clean a HVLP Spray Gun – Actionable Guide for DIY’ers)

Common issues with HVLP paint sprayers

If you are using an HVLP paint sprayer, there are some common issues that you should watch out for. If you have an orange-peel look to your chrome, you should use more solvent and make certain that you are not standing too far away when you are applying it. If the material has runs or sags, add additional product because your mixture is too thin. If you see pin-holing, you need to make certain to apply your coats in thinner layers. Most of the common issues that people encounter with HVLP paint sprayers are things that they learn to avoid with painting practice.
