We began using an Iwata spray gun many many years in the past at the college that I instruct. Immediately after working with the gun, I beloved it. Most college students that have no choice select the Iwata as their gun of decision as well. So if you might be looking to purchase a new gun, I endorse an Iwata spray gun. The Supernova with a 1.3 is my favourite. Having said that, the suggestions that I am likely to share with you can be applied with any spray gun.
1. Regulate The Air Tension
The 1st point that I normally do is to set the air tension. Be certain to seem at the complex info sheet for the product or service that you will be spraying. This facts sheet will give you a suggested air strain setting. Nevertheless, pay out awareness if it states at the inlet of the gun or the nozzle. Big variation. If it claims 10 cfm at the nozzle and you set it to 10 entering the gun, you are going to have issues. You will not have plenty of air strain, which will end result in the paint not atomizing appropriately and spraying too much orange peel.
Applying my Iwata, I use an air regulator on the end of my gun. I set it everywhere from 18 to 24 psi. The air pressure is likely to be unique depending on the spray gun you have. For Iwata 18 to 24 psi usually functions great for most coatings. As pointed out, too very little air stress will less than atomize the coating (orange peel), and also a lot air stress will around atomize, which will lead to too significantly about spray squandering paint and leading to the over spray to land back again onto the floor leading to the paint to seem dry.
2. Regulate The Pattern
The pattern adjustment will alter the pattern from a little ball to a huge admirer shape. If the pattern is not wide plenty of, you are heading to have operates and stripes in your paint position. If the pattern is as well extensive, you might have very poor protection and squander paint elements. With the Iwata spray gun, I open up the sample open up all of the way. Then I start off closing the adjustment until eventually I commence to see the sample begin to get smaller sized. As soon as it is to that stage, I cease and make my upcoming adjustment.
3. Fluid Adjustment
This is likely to depend on the style of product your sprayed. For crystal clear coat, I open up the adjustment to greatest to allow for a whole lot of fluid to come out. If I am capturing base coat, I will regulate and near the knob about 3 or 4 turns to allow for fewer fluid to be sprayed.
4. Fine Tuning
I have the gun established, but it requirements to be great tuned to my techniques. Initial, the more changes may perhaps have improved my air pressure, so I will readjust the psi if desired. Upcoming, I will spray a take a look at pattern on our spray cart. If it is running or appears to be much too thick, I will widen the pattern. If it is not masking effectively, I will slender my sample. And finally, I will adjust the quantity of fluid. If it feels like too much, I will regulate for much less fluid, and if it does not experience like plenty of fluid is coming out, I will improve the fluid adjustment.
The previous tip that I can give you is to apply. That is what it requires and do not be afraid to make changes. Make your spray gun suit your system, as a substitute you changing your technique to match the paint gun. The spray gun recommendations were with an Iwata Spray Gun in thoughts, but any other paint gun that you might be making use of will follow the very same measures.
