What happens here

When using an airless paint sprayer, it is crucial to select logical start and stop points on the surface you are painting. This means avoiding stopping and restarting your spray in the middle of a flat panel or section of siding. Instead, identify natural breaks such as the edges of windows, doors, or corners of the building. Stopping at these points will prevent a visible build-up of acrylic paint (which appears as shiny lap marks) that can occur when you overlap wet paint on partially dried paint in an open area. For hard-to-reach areas or high surfaces, utilize specialized tools like gun extensions and angle adapters to maintain continuous passes without awkward stopping. This technique is especially important for non-absorbent materials like aluminum siding where excess paint tends to sit on the surface.

Goal: To avoid lap marks and shiny spots on painted surfaces, select natural architectural breaks like windows, doors, or corners as your start and stop points, rather than stopping in the middle of a large, flat area. This prevents acrylic build-up where paint overlaps.

got um aluminum sighting right here that we're spraying. And one thing, the gentleman that sent the pictures in, he had some lap marks. And every time you overlap on aluminum siding or really any type of structure you're getting to or having start and stop marks, you're getting a build of acrylic right there in that in that area or where you're overlapping. It's heavier there than the rest of the structure that you're spraying. And what happens is you will notice that over time as it begins to fade or wear out the paint because you got more acrylic in one area than you do the rest of the areas. And on absorbent structures, um, like concrete sighting or wood sighting, it's going to absorb some of the acrylic out of the paint out in the field, but where you overlap, it's going to be built up and you will see that. You could see that even the next day like the gentleman that sent in the pictures. I'm going to give you three tips. This is going to be one of those situations. If you have overlap marks, you could get acrylic build and you could see those um spots. So, one of the thing is choosing logical start and stop points where you're not ending in the middle of the field someplace. If I end anywhere in the mi middle and then I come back and overlap the opposite direction or if I don't walk in to end, all those overlaps could show. So, logical start and stop points in between two windows is a logical start and stop point. If you got long runs, you got to try to make it so you can walk those long runs so you don't have start and stop. Sometimes once you get on high sides, it's really difficult, but that's where gun extensions and um angle adapters will help you out. So, logical start and stop points are very critical to eliminating overlap marks um or what we called acrylic build. So, tip number
