What happens here

Beyond overspray, the speaker warns that larger tips can lead to excessive paint application, resulting in runs and sags. Crucially, he emphasizes the importance of applying paint at the mil thickness specified by the paint manufacturer's Technical Data Sheet (TDS). Applying too much paint can cause defects like crinkling or "alligator peeling," affecting the paint's performance and appearance. Conversely, applying too little paint (not meeting the specified mil thickness) can void the manufacturer's warranty. He highlights that his method of spraying with a 515 tip and overlapping by 50% consistently achieves the desired mil thickness, which can be verified with a mil gauge.

Goal: Ensure paint is applied at the correct mil thickness using proper techniques to prevent defects and maintain warranty.

Tools and materials

  • Airless sprayer — Applying paint to surfaces
  • Airless sprayer tip — Recommended for achieving proper mil thickness with 50% overlap

What they say

larger tips is the more possibilities of runs and sags. You are getting a lot of paint on there, but one of the other things is is that TDS specifies, you know, how much paint you need to put on there, you know, for the paint and for the paint to perform better. What you could end up getting is more paint the heavier it gets. If it gets too heavy, you can get like crinkling and what we call like alligator peeling and stuff. So, there are issues that come with putting on the paint too heavy. You want to apply it on, you know, per the specifications, you know, for a lot of different reasons. So, if you try to go down, say a smaller tip size, you might not be getting on enough paint. The paint won't perform. If you end up having a warranty claim, they'll come out, test the mill thickness of the paint. It's not the proper mill thickness and they're not going to cover the warranty. When I'm spraying, I'm using a proper method. I spray and I overlap 50%. When I tested it with a mill gauge, I would be getting the mill thickness that I want that is, you know, that goes by the specifications in the TDS. Over the years, I've used a lot of different manufacturers of tips. You know, there's Graco, there's Titan, there's Bedford, there's Trit. Exit Flex now makes tips.
