Gone are the days when paint brushes were used for completing difficult painting tasks. Now paint sprayers are considered to be the most convenient way to complete the painting job in a fraction of time.
Among them, HVLP spray guns are highly professional spray guns that are suitable for painting various households including cabinets, furniture, and vehicles, offering a smooth finish with higher speed and accuracy. After completing the painting tasks, cleaning and maintaining the HVLP spray gun is also very important.
What Solvent To Use To Clean HVLP Spray Guns?
Acetone is considered to be one of the most effective solvent for cleaning HVLP spray guns. The main function of this solvent is that it easily dissolves grease and paint. Also, it can be used for cleaning the disassembled parts.
For cleaning these parts, you need to soak them in acetone and leave it for some time. Furthermore, acetone is also cost-effective, easily accessible, and safe to use.
2. Lacquer Thinner
This solvent is also a highly effective option for cleaning the spray gun. The lacquer thinner is like acetone but is not safer as acetone. The most important thing that the user needs to remember is that this solvent is highly flammable and should be used with precautions.
In order to clean the spray gun, the foremost step is to disassemble the spray gun parts. After that place these parts in the container and soak it in the solvent for a few minutes. By using a dry cloth, clean the wet parts.
3. Cleaning Kit
Cleaning of the spray gun is very important if you are its frequent user. Investing in a better spray cleaning kit will make the cleaning process easier and less time-consuming. The best part of these kits is that they can be used for cleaning all types of spray guns. These kits contain 15 different types and sizes of spray brushes that are specifically designed to reach all the crevices and cracks. Among the two solvents, acetone is considered to be one of the safest solvents included in the kit.
4. Natural Cleaners
Natural cleaners are an affordable and effective solvent that can also be used for cleaning the HVLP spray guns. Furthermore, citrus-based cleaners are highly suitable for oil-based finishes and can also be used to thin the paint.
An important reminder for the users is to never use natural cleaners with water-based paints. Apart from this, a mixture of regular dishwashing soap and water can also be used for cleaning the spray guns.
5. Cleaning The Coats Of Paints
There are lots of DIYs available for cleaning the spray guns having different layers of the same color. On the other hand, if the spray gun is sealed properly, there is no need to disassemble the parts for cleaning. However, the easiest way is to remove the paint nozzle and rinse it out thoroughly to clean all the clogs and dirt.
Furthermore, for oil-based paints, leave the nozzle in the cleaning solvent for a few minutes and then clean it with a dry cloth. The users can also use the moist rag to clean the nozzle and wrap it up until use it again. While cleaning, make sure to rinse the nozzle with any solvent before the next application of the paint.
Also, the paint should be left in the spray gun for almost 3-4 hours while waiting for the paint to dry. Leaving the paint in the spray gun for a longer time period will make the cleaning more difficult and challenging.
6. Disassembling Of The Spray Gun For Cleaning
The first and foremost step is to remove the air regulator from the spray gun by disconnecting the electrical source. After that, the next step is to empty the spray gup cup and add a small amount of solvent into the cup and wipe out all the paint residues. The next step is to remove the filter which is located at the base of the tube. Fill the cup half with the solvent and whirl it around by sealing the lid.
After that reconnect the paint gun with the turbine and hose and spray the solvent solution all over. Make sure that this process is done in an outdoor or well-ventilated area in order to prevent the inhalation of the solvent. The process is repeated till the solvent clears out all the paint residues. After completing the process use the damp cloth or rag to clean up all the parts and cup properly and also wipe down the lid as well.
Moreover, while cleaning the parts of the spray gun, make sure to clean the valve from the paint residue. Finally, the user will need to lose the fluid control knob and be careful not to lose the spring. With the help of a wrench, slowly free the nozzle at the front side of the spray gun.
After that soak the fluid nozzle, needle, and air cap into your favorite solvent for cleaning. In order to tackle the hidden and stubborn paint stains, make sure to use a small cleaning brush for proper cleaning.
