I'm having trouble with overspray on the backsides of my doors. When I spray, I start with the backside of the door, then I do the front side and the edges. When I do the edges, I get the problem of the overspray on the underside of the door, making it unsmooth. Now I spray the backside first and I do the edges at this time. Then I change over to the front and spray straight down and don't do edges. This solves my backside problem, but I get overspray on the edges of the door, which makes them unsmooth. How do you spray your cabinet doors so that you get no overspray on any side or edge?
The finish may be bouncing off of what you are sitting the door on.
Spray all four edges of stacked doors twice, keeping your gun parallel to the edges. Let the stack flash for 5 minutes, then spray the back surface of each door as you work down, and unload the stack. When the backs are flashed and dry, restack face up. Spray the edges once and then spray faces as you unload. You can also make screw boards of longer lengths. At work, I use the small screw boards for edge work and then transfer the doors onto 12' long boards to do face and back work. That works even better, as you can set the doors up side by side, spray all backs at once, flip 'em all at once, 2 coat the fronts and let them dry undisturbed.
