So I have my 90" screen up on the wall. I don't think that I would go this route again but I have a 1/2" piece of mdf screwed into the studs. I have sprayed at least 9 coats of Kilz on it to seal it up but I am having trouble with the paint laying down uniformly. At first I thought it was the mdf absorbing the paint but this many coats into it I'm not so convinced. I am running an HVLP gun and am much happier with the atomized finish as opposed to rolling but I just can't get a uniform finish across the screen. I have attached a shot that shows the non-uniform spray pattern (see the horizontal and vertical lines?). :hissyfit: Looking straight on at the screen, you can't see anything and it looks great when projecting an image onto it, but with the projector off and looking at the screen from an angle, the spray pattern looks horrible. I want the screen to look as good off as it does on (sorry, I'm like that). I think my problem has to do with the narrow field of paint the gun is throwing down and me not making my passes close enough together. However, I'm worried about getting my passes to close together, not going straight up and down or left to right and creating runs by putting to much paint in one spot. I am using the 1.4mm tip and amrunning 40 psi at the gun with the trigger pulled.
My question is, does anybody have any recommendations for correcting my problem? If not, then I am looking at just rolling on the BW paint. I really want the fine finish of spraying but if I can't get it on uniformly, then what good is it? :dontknow:
Anybody with any thoughts or opinions? Here is my frustration. Thanks in advance.
