You want to paint your car and you have chosen an HVLP spray gun for your project. This is the best choice. You can do much of your work with a high-volume, low-pressure (HVLP) spray gun.

This technology offers more advantages over older high-pressure paint guns. And it will let you do your painting even quicker, and with better cost-effectiveness. HVLP spray gun even offers a few improvements that contribute to the safety of the painting professionals who use them. But there may be a question about how to paint a car with an HVLP spray gun. Now, we will try to answer this question in our article.

Firstly, we need tools which you use while working. Then we paint the edges first with an HVLP spray gun. This offers us a chance to control the paint in the hard-to-reach areas first, then get into the simpler flatter areas last. We must carry out before starting work a test spraying of paint on the surface of a car. After testing, we can start painting. We should wait for it to dry and then you will see the result.

How to paint a car with a HVLP spray gun

What is an HVLP spray gun?

If you want a spray gun that’s available, an HVLP spray gun might be right for you. HVLP means High-volume low pressure.

These spray guns are similar to typical spray guns in that they use a compressor to move air through the gun. But, unlike regular spray guns, HVLP spray guns distribute a higher volume of air at a lower pressure.

HVLP spray guns paint finishes at high volume and low pressure. Cabinetmakers and furniture builders like to use HVLP spray guns for their projects.

Using HVLP spray guns can be ideal for trim, finish work, furniture staining, cabinet painting, and any detailed applications where you need high accuracy, speed, and a smooth finish.

There are two types of HVLP spray gun systems that are a dedicated system and a conversion system.

A dedicated system employs a turbine to atomize the finish. These systems are small and portable, however, they are not cheap.

A conversion system converts the high-pressure air from a compressor to a lower pressure to create a lower volume, more controlled spray.

If you have these things, you can start the process.

  1. Put on your protective wear 
  2. Take time to consider where you will spray
  3. Check that your painting area has an electrical power supply
  4. Clean your painting area
  5.  Prepare your LVLP gun and compressor with reference to the manufacturer’s instructions.
  6. Pour the paint carefully into the paint cup
  7. Switch on the compressor, select a narrow tip for fine atomization (1.3 mm or below), and set your LVLP gun to the lowest pressure setting — both on the gun handle and the inline regulator.
  8. Spray your car from the top downwards 
  9. Using a step stool where required, this is the pro-order of painting a car:
    • Roof.
    • Hood.
    • Trunk.
    • Front side panels.
    • Doors.
    • Rear side panels.
    • Exposed interior areas.
  10. Spray from a distance of 8-12 inches using long, slow, steady, side-to-side passes. 
  11. Allow the topcoat sufficient drying time

By following these steps, using the correct equipment, and with a little practice — you may become an LVLP car spraying expert.

HVLP spray guns have less overspray.

One of the biggest pros of HVLP guns is that they may get a paint job done with less paint. This is largely the reason that they have less “overspray,” which is a phenomenon in which excess paint collects on and around the surface being sprayed. HVLP guns spray in a way that avoids that kind of accumulation of extra paint on the surface.

Having less overspray refers to car painting professionals having to spend less time getting the overspray off of a vehicle. This process sometimes includes using solvents and specialized tools to remove the excess. This may take time, and demand a good deal of care.

HVLP spray guns offer better transfer efficiency during car painting.

Not only do HVLP guns do a good job of not spraying excess paint onto the surface of a car, but they also have perfect “transfer efficiency.” This refers to the quantity of paint that is shot out of the gun and that then sticks to the surface of the car. Higher-pressure delivery systems will cause paint to get better on a car, while HVLP guns do not have a great deal of that problems. According to Hotrod, the distinction may be as much as a 65 percent transfer efficiency rate for HVLP versus a 25 percent rate for high-pressure guns.

HVLP guns shoot less paint into the air, which is better for your health.

When you use paint guns of all varieties in car painting careers, a cloud of microscopic paint droplets is released that is not good for a person’s health. That is why car painting professionals put on a breathing system when working on a car, though residual paint in the air means that protection still is a problem even after the job is done.

HVLP guns shoot less paint into the air than high-pressure guns do, which cuts down both on the paint that a mask needs to take care of and on the amount that hangs around afterward. Overall, it’s a quite big advantage for you, and a big reason why you ought to use an HVLP gun. Of course, standard warnings still apply. You should always paint in a well-ventilated area and utilize a breathing system when using an HVLP gun.

How To Paint A Car With An Airless Spray Gun

Airless paint sprayers are popular as a speedy alternative to other methods of painting with a consistent, high-quality result.  Airless sprayers are so easy to use that you can paint your car very easily with airless spray guns. If you have decided to paint your car with an airless spray gun, but don’t know how to use it, let’s read the following tips.

10 Tips to paint your car with an airless spray gun:
  1. At first, adjust your gun properly to get the ideal finish.
  2. Clean the surface for painting. Painting with an airless spray gun should involve some preparation in the surrounding area.
  3. Use sandpaper for the whole part of your car. It helps to be clean from spots.
  4. Fill the spray gun with paint.
  5. Hold the sprayer’s trigger to spray. If you are using a paint sprayer, you should practice on a throwaway surface first. You can do a practice spray with water.
  6. Adjust the pressure. If the paint isn’t spraying evenly and thickly, it’s a perfect sign you should increase the pressure. There is a dial on your airless sprayer to control this with. However, you should try to keep the pressure as low as possible. Unnecessarily, high pressure wears out the sprayer faster.
  7. Keep a steady distance when you spray. You should keep your sprayer between 10-12 inches (30.5 cm) away from the surface you’re painting. This makes it close enough to apply effectively.
  8. Keep your moving. If you hold down the trigger in one place for a long time, you’ll run the risk of overspray and dripping. To prevent this issue, you should make sure your hand is always moving over the surface you’re painting.
  9. Release the trigger to stop painting. When you have done a certain round of painting, simply release the trigger to stop painting. You should account for the split second between the time you release the trigger.
  10. Clean the sprayer after use. It’s a good idea to clean out your sprayer after every use. Don’t leave the sprayer idle for more than 20 minutes. If you do, the paint will begin to harden.

Which spray gun to choose?

If you don’t know which spray gun to choose for painting your car, now we will give some information about them.

If you hesitate about which type of gun you select, you may pay attention to other factors such as feed type and nozzle size.

HVLP, which stands for “high volume low pressure,” are well-known spray guns today. It offers a controlled spray with little overspray. Some HVLP guns are powerful that you can use them without an air compressor, whereas others demand a large air compressor to operate.

LVLP stands for “low volume low pressure,”. This type of spray utilizes less air volume than HVLP paint guns. You can use these guns with smaller air compressors and they have fewer air requirements than HVLP spray guns.

If you choose the LVLP spray gun, it is up-to-date and devoid of most of the shortcomings. Both, LVLP spray guns are also more economical and they transfer up to 75% of the consumed paint to the surface (HVLP usually transfers 65%) and consume much less electricity to operate the compressor. These are good tools available today. 

Both gun systems are appropriate for low to medium-viscosity materials, base coats, and two-component clear coats. You may use HVLP and LVLP for both amateur and professional use and repair of a large flow of cars. You can equip HVLP spray guns and LVLP spray guns with interchangeable nozzles. 

As you see, HVLP and LVLP spray guns are excellent tools that not only amateur car painters can utilize, but also experienced craftsmen use them.
