The I think I found the sprayer you're talking about, it is pretty cheap.
It is Latex, and it sands down just fine using a medium Grit (100) "LARGE
Sanding Sponge" (3" x 8" x 1") Use wise, sweeping strokes that gently "Kiss" the surface....not press it inward to any real degree.
The proper procedure is this:
Use a 1/4" or 3/8" Nap Roller of the best quality you can manage. Dampen it first with water, then load it up to where it doesn't drip, but the Roller cover is saturated.
Apply the Primer normally, not "lightly" nor "heavily", and do so with a degree of care commensurate as to it being a surface you'd want to look at "as is"...therefore with no roller marks...at all. If after the first Coat drys, and you lightly sand it, you determine another coat is called for, "that" coat should be done a little lighter...then also lightly sanded.
Do that, and you should have an excellent surface to proceed with.
Now...your either gonna Roll or Spray the Finish coats. Lemmie tell ya sumpthin'.....if you do opt to spray, the job goes really fast...each of the required 3-4 coats go on in less than 50 seconds for a 100" surface...and the finish is an order of magnitude better than you could ever roll on when using a high performance Mix.
The "No Name" sprayer?(Graco 2900) http://www.gleempaint.com/noname.html
I've got 2...plus a $80.00 Wagner CS Plus, and since I got the No Name, it's all I use. It's a great little Job-doer, and you better believe you'll get plenty of other use out of it.
Just re-post if you get it, and if you cannot find any of the many Videos or comprehensive tutorials on spraying I have already posted, I'll be sure to hook you up.
If you roll, you own your own.
