Most importantly, these spray guns are easy to apply and use. With its 1.8-millimeter nozzle diameter, the spraying surface area is neat and precise that gives good handling during the spray. It is also versatile in any spray-painting surface.

Also, the pressure compressor at the tip of the nozzle makes it a low-velocity spray gun, making the controlling process even more accessible. Keep in mind that HVLP spray guns are not suitable for the thick coating of spray paint.

Furthermore, the spray surface also depends upon the nozzle type and fluid. In other words, HVLP spray guns are suitable for small projects like painting a bookshelf or redoing the kitchen cabinet.

We suggest using conventional spray paint guns for large projects such as painting the hard deck. On top of that, HVLP guns require good practice before starting to paint on a natural surface. Therefore, do your own research before purchasing a suitable model of HVLP spray gun.

Substance To Clean HVLP Spray Guns

Let’s say that you have chosen a suitable HVLP spray gun to perform the spray painting around your house. Another disadvantage of HVLP spray guns is that they require immediate cleaning after the painting; otherwise, the paint stains will make the spraying uneven.

Therefore, it will be wise to know what substances are available that can help clean an HVLP spray gun very smoothly. Down goes some names that are proven to be most efficient:

  • Acetone.
  • Lacquer Thinner.
  • Spray Gun Kits.


A ketone-based compound always works best when cleaning paints from any metal surface. Acetone works as a solvent that helps to dissolve the paint inside the nozzle of the HVLP spray gun.

Furthermore, you can also use Acetone to clean other equipment related to the spray gun. This chemical is harmless, cheap, and available at every local store nearby your house.

Before cleaning the spray gun, experts suggest dipping all the equipment and the gun in a significant volume of Acetone. After that, remove the pieces and rinse with a towel to clean the outer layer.

Lacquer Thinner

Lacquer thinner is another solvent that can be used instead of Acetone. Pour all the parts of an HVLP spray gun into a bucket and pour Lacquer thinner. After leaving the mixture for many minutes, wash them with a brush, and you will notice the stains coming off the spray gun surface.

One thing to be careful about while using Lacquer thinner is that it is highly flammable. Do not expose this chemical near a fire source! Therefore, one must be careful and wear protective hand gloves and goggles before using Lacquer thinner.

Spray Gun Kits

Apart from the two chemicals mentioned above, a dedicated kit is available in the market designed to clean HVLP spray guns, known as an HVLP cleaning kit.

This particular kit comes with 15 different sizes of brush that can be used to clean or rinse any part of the HVLP spray gun. Additionally, you will need a suitable solvent, and our research says that Acetone works best and is also not explosive in the cleaning stuff.
