What happens here

When spraying, always aim for a 50% overlap with each subsequent pass. This means that half of your current spray pattern should cover the edge of the previous, freshly applied paint. This technique guarantees an even distribution of paint across the entire surface and achieves the recommended mill thickness. Proper mill thickness is vital for the paint's performance, longevity, and to ensure any manufacturer's warranty remains valid. Too little overlap can lead to thin spots and premature paint failure, while excessive overlap can cause runs or excessive build-up. The video specifically recommends using a 515 airless spray tip as a versatile size that allows for good control of overspray while still applying enough paint to achieve proper coverage without having to move too slowly.

Goal: Maintain a consistent 50% overlap between each spray pass to ensure an even and proper mill thickness of paint. This uniform application is critical for both the paint's aesthetic quality and its long-term durability, often affecting warranty validity.

we called acrylic build. So, tip number two is overlapping 50% when you're spraying. So, when I'm spraying, I want to overlap 50%. That way I'm ensuring that I'm getting enough paint build on my surface. I like spraying with an a 515 tip. And the reason why I choose a 515 tip is because I can control overspray with a 515 tip. If you start to get too large of a tip size, the droplets are going to be too heavy and you can start to have overspray. Too small of a tip size and it's not going to put on enough paint. You're going to have to paint really slow. 515 is right there in the middle. But you want to overlap 50% that way you um ensure that you're getting the proper mill thickness to paint on there. Now paint specifications require a certain mill thickness. So until you get familiar with your paint and how slow you got to go or how fast you got to go and how much you got to overlap to get the proper mill thickness. Proper mill thickness is important because that's what's going to ensure you get your warranty out of your paint. If the paint fails, the company's going to come out and they're going to one of the things they're going to do is test a mill thickness of the paint. Is it on thick enough? If it's not, they're not going to warranty the paint. So, over the years of spraying, I've come up with how slow I need to go or how fast I need to go and how much I need to overlap. And that is 50%. And that ensures that I'm getting on the proper mill thickness. So, your spray powder, you're going to spray one direction, you're going to come back the opposite direction, and you're just going to overlap by 50% as you go, and you'll get good coverage by doing so. All right, tip number three is
