thinning paint for sprayer

We just started using a spray gun for the first time. We are almost finished priming and are getting ready to paint our kitchen cabinets. We are using a latex paint which says not to thin it (it is Sears Easy Living Lifetime). The spray gun (Wagner) instructions say that thinning will help with coverage. Does anyone have any experience with this latex product? Would it be okay to use Floetrol to thin the latex paint? The floetrol says that it will not adversely affect the paint. I would sure hate to start painting and end up with paint going on clumpy if I don't thin it. But I don't want to thin the paint if I shouldn't. Help! Any advice from someone with experience with this would be greatly appreciated.

 

khenderson, you wouldn't get far into the topcoat before you realize thinning is a must. Can directions are for brushing/rolling. Most paint can directions state for spraying a certain amount of thinning is needed but it is never enough. The paint should be fogging out of the gun rather than spitting. Finish painting with a Wagner and latex must be the hardest thing to get right IMO because by the time the paint is thin enough to really spray its going on so fast its hard to control. Best advise: try the Flotrol (its supposed to make latex self level like oil), practice with some scrap paint on something and use the smallest tip that will spray correctly. The first couple of passes should be tack coats and will be VERY light, most often no where near covering. Good luck...Mike
