Compared to a regular spray gun
, a high volume low pressure (HVLP) spray gun
is better for finer coatings and finishes, minimizing waste and fumes. HVLP spray guns use a turbine instead of a compressor to provide air. This allows for more accurate and precise spraying, less overspray, and less air pollution. HVLP spray guns are designed to atomize fluids softly with air pressure reduced to between 0.1 and 10 PSI at the air cap. Using this pressure reduces the risk of severe skin injuries.
These spray guns are perfect for applying paint and other coatings to furniture and other surfaces. They are also useful for trim work, cabinet painting, and interior baseboard trim. HVLP guns are great for small projects that are relatively consistent. They can also be used for detailing expensive paintings.
While HVLP spray guns are convenient and effective, they are also expensive. You can expect to pay several hundred dollars for a professional model. For a cheaper option, there are several DIY models available that come with turbines. These turbine models are lightweight and easy to move. They are also great for spraying siding and other small decks. You'll need an air supply hose to connect the gun to the turbine. You also need to make sure the turbine exhaust is not in the spray area.
These turbine models also provide better spraying quality than compact models. A high-quality turbine will offer consistent performance and durability. You'll also want a hose that's long enough for the job. Many professional models come with longer hoses, but they're not usually available for DIY models.
You should also make sure to clean your HVLP spray gun after each use. Many models are designed with a bristle brush, which should be used to keep the gun clean. You can also purchase complete aftermarket HVLP spray gun cleaning kits. This is a great option, especially for those who don't have the time to clean their gun after each use.
You may also want to wear protective clothing, such as gloves, safety goggles, or a face mask. You'll also want to keep the gun at least 6 inches away from your project. You should also wear ear protection when spraying for prolonged periods.
Some professional HVLP spray guns also come with an air compressor. This can make it a bit more difficult to clean the gun, but it can also provide better coverage. The downside of this option is that you'll need a powerful compressor. This can also cause a lot of noise. If you aren't careful, you may also run into a problem with dried material. You may also need to scuff sand between coats.
When spraying with HVLP, you should also follow the instructions on the technical data sheet. Some coatings may require thinning, but you shouldn't have to thin paints that are waterborne. Most coatings have high solids content, so you may need to use thinner to get the best coverage.
