How To Operate An HVLP Paint Sprayer

For any painter, an HVLP paint sprayer is one of the most important tools. For starters, HVLP is an acronym standing for high volume low pressure paint sprayer. The tool is designed to use minimal paint to cover large surfaces and can work well with both water-based and solvent-based materials of coating. An HVLP paint sprayer is therefore efficient, effective and worth your money and time. However, to get the most out of it, you must know how to handle the tool perfectly. If you are a beginner, worry not because this article takes you through the process of how to operate an HVLP paint sprayer effectively.

1.Get the Coating Material Ready


As aforementioned, an HVLP paint sprayer works well with both water-based and solvent-based coating materials. In that case, when operating the tool, it is important to mix the coating material according to the instructions provided by the manufacturer. Regardless of how experienced you are in the field of painting, reading and following the instructions that comes with the package is always recommended. 

2.Fill the Cup with the Coating Material

Once the coating material is mixed to the required proportions, it is time to fill it into the HVLP cup. Depending on the design of the tool, the cup is always removable for easy filling. Remove the cup, fill it with the coating material then close its lead. Fix the cup back to the sprayer and ready yourself for the next step. 

3.Adjust the Compressor

 The compressor is the part of an HVLP paint sprayer that powers it. By powering it on, the coating material will travel to the HVLP paint gun depending on the pressure set. For starters, it is always advisable to set the air pressure at 90psi because many HVLP spray guns have their own pressure regulators. Because more and more types of HVLP paint sprayers continue to flood the market, it is advisable to adhere to the manufacturer’s instructions because they may vary from brand to brand. Additionally, your paint spraying projects will dictate the amount of pressure needed and the type of adjustments to be made. 

4.Attach the HVLP Spray Gun

As its name suggests, the spray gun is responsible for directing paint to the painting surface. After adjusting the compressor, fix the HVLP spray gun and press down on the trigger. For most paint sprayers, you will notice that there is a fluctuation at the gun’s base once you hold on the trigger. When that happens, hold tight until the fluctuations end. 

5.Test the Spray Paint

For any painter, it is always wise to test both the paint and the HVLP paint sprayer before painting the real surface. You can do this by spraying on a plywood or any other surface that is of less significance. Throughout the test, observe how the paint is running, the speed of the fan and the quality of the paint. From the test, you will know whether to re-mix the paint, adjust the pressure or continue with the project.

6.Painting Techniques

Unlike other types of paint sprayers, the HVLP paint sprayer is one of the easiest to control and use. Once you have adjusted the fan properly and have ascertained that the paint if flowing perfectly, it is time to start the actual painting process. According to most of the painting experts that I have come across, it is important to keep the spray gun about 6-8 inches away from the spraying surface. This will allow the paint to spread evenly and be heavy enough to become solid without overdoing it. Excessive paint will make it very difficult to finish and level the painting surface while underpainting will not give you the desired results. 

For beginners, it is advisable to always hold the spray gun perpendicular to the spraying surface. This will ensure that only the parts you want painted will be painted. Additionally, when moving the spray gun, concentrate on the starting point for a few seconds before moving to the other parts. Always start from the upper side of your painting surface while moving to the bottom as it will minimize the chances of the paint overrunning to the parts that are already painted. 

When at the end of your painting surface, you can continue painting a few inches further for a smoother finish. It is important to note that holding the trigger and directing the sprayer gun are very necessary techniques and play a huge role in determining the results of your project.
