HVLP stands for High Volume Low Pressure’, and refers to how a sprig gun atomizes paint. Contrary to a standard gun, the HVLP sprayers make sure you get reduced paint waste by around 50%. Note that these guns save on the pressure to ensure reduced costs.
However, understand that you simply can only get the advantages of an HVLP applicator if you employ it correctly. Luckily, we've put together a comprehensive guide on the way to found out a sprig gun. Learning the way to configure your gun will assist you in economize, paint, and time.
Preparing for the
Set-Up
Setting up
your HVLP applicator requires three main steps: air supply choice, finding the
proper tip, and final setup. Understand that the steps above will assist you to
get a knowledgeable and smooth finish. you'll also complete projects quickly
with no glitches.
Air Pressure and
Volume
Setting up the volumes and pressures of an HVLP applicator will involve tons of trials and errors. For starters, ensure your applicator is about six inches high. Use your fan-control knob, located on top of your sprayer, for this setting.
The material push is additionally located on top of your applicator. However, understand that configuring this setting will take some practice. for many sprayers, you'll be got to unscrew the fabric push at around 2.5 turns.
Understand that your HVLP applicator needs tons of air to figure effectively. The user manual will indicate the quantity of air you would like for each minute. Note that you simply need to generate the specified volume continuously using your compressor. You must, therefore, make sure that your compressor has the proper capabilities to handle the HVLP applicator.
Ideally,
you would like about ninety pounds for each sq in. Furthermore, use your HVLP
controller to line the specified amount of pressure. Once you've got the
atmospheric pressure and volume found out, you'll advance to the second step.
Finding the proper Tip
The tip you
select is a crucial consideration. Most spray guns accompany a couple of tip
sizes to assist you to get the right finish. the fabric you employ will dictate
the proper tip size for the work. Understand that different types of paint have
different densities and compositions.
You will need a 1.0 spray tip for little tasks like one panel. However, a 1.3 tip is that the perfect choice if you would like to wash your car or do tons of painting. Understand that you simply must consider the task at hand and therefore the sort of material when choosing the proper tip size.
Primers
will need a much bigger tip to make sure you get a smooth finish. A 2.3 or 1.8
tip size would be sufficient for primers and other thicker materials. make sure
you undergo the user manual to assist you to discover the proper tip size for a
specific project. you'll always invite assistance when purchasing a primer or
paint. Note that finding the proper tip size will assist you to get a smooth
and consistent finish during a project.
Final Set-Up
An HVLP applicator must be properly found out before you'll use it. However, note that humidity and temperature also can impact how your applicator shoots. With the right setup, you'll find it easier to figure on differing types of projects.
Understand that skipping this step will cause a poor finish. the foremost convenient way of completing the setup is thru a sprig test. Start by taping paper masking on your wall and use the regulator to regulate the pressure. Because air remains being pulled, make sure the control knob is left closed.
Next, open your fan control knob and make sure that it's six inches high. The applicator also must be a minimum of six centimeters faraway from your surface. the space between the wall and therefore the sprayer will make sure you get a smooth and professional finish. you'll then turn on your material control knob and point your applicator at the masking tape placed on your wall. Pull-on the trigger gently, but make sure you don’t hold it for long.
Note that the masking tape will reveal a sprig pattern in cigar form. you want to make sure that the patter is about 9-10 inches long. the center covering will look full while the sides will fade. Mastering the spray pattern will assist you to get a uniform and smooth finish.
If you notice an excessive density on either side or not enough at the middle, then you would like to regulate the airflow. Understand that an excessive amount of airflow or insufficient airflow will interfere with the spray pattern. you want to attempt to limit the airflow by screwing the fabric knob once you notice an excessive amount of overspray.
Now you
would like to check out the trajectory of your gun to make sure you get a
robust compressor. This step is vital especially if you're uncertain about the
proper pressure or CFM. Use your spray gun’s base controller to vary the
atmospheric pressure and keep your lines dry using an air dryer.
Testing
Testing is a crucial step to making sure you're ready for your painting project. make sure the test conditions are ideal by checking that your applicator is correctly installed. The applicator must be about six inches from your surface. you want to also hold down the trigger for a few seconds during the testing. Following the above guidelines will assist you to get a correct reading of your found out.
However, don't forget to vary the fan and atmospheric pressure control accordingly during the testing. Note that each one of the controls got to work together seamlessly to urge you a far better finish. you'll always attempt to make one control setting to catch up on the opposite.
You will know that you simply have successfully found out your HVLP applicator once you have a cigar pattern of about 6 inches high. Note that you simply also will have full center coverage and a touch little bit of fading on each side.
Conclusion
When using an HVLP applicator, you would like to attenuate overspray the maximum amount possible. Understand that you simply will have the littlest possible droplets during your project. increasing atmospheric pressure is among the simplest ways of reducing droplets from your applicator. Once you get a smooth and professional finish on the test paper, you're able to start your project.
