Its the different layers I'm cornfused about!!! Lol and I don't know much....
Most all Fuji Sprayers are pretty good rigs....and more expensive than most DIY'er would consider. So I'd venture to say you "all good'. I'd like to ask though what size Needle / Nozzle assembly you have?
After you make sure the surface to be sprayed is as smooth and even "texture-wise' as possible, you will use thinned primer applied using the "Duster method". Usually, anyone with experience using thinner Shellacs and Varnishes can intuitively judge how much material is going up, and the rate / distance / row overlap one has to maintain to avoid Runs, Sags, a build-up that creates Orange Peal, or Horizontal striping from not overlapping the rows enough.
One very important aspect to consider when using Drywall is the differences in texture between sanded smooth Drywall Compound and Drywall paper. It is very advisable to lightly skim the entire surface between the mudded Joints / Screw heads with Compound, let dry, lightly sand, then repeat over "everything"...once again...with a very light skim coat of compound. Then, after a light, even sanding, you'll have as perfect and as even a surface as can possibly be achieved on a Drywall surface. and that sir, will provide a very substantial advantage as spraying on the Primer / finish coats commences.
I apply at least 2 Coats of primer via Duster, lightly sand, then apply a 3rd coat.
Then with the Finish paint, I do exactly the same, except I will sand only if I feel it necessary...after the 3rd coat, then apply 1 or 2 more light Dusters after that. keep the coats very light by applying the spray from 14" and maintaining a rapid transit across the surface. And also, be very certain each prior coat is dry before applying another. Use raised / applied heat until the surface sheen is gone
, then if possible, a light breeze from a clean "elevated" Fan set 6' - 8' away at center to hasten the paint into a truly dried state.
Thanks for holding on for a reply. I am looking forward to your ongoing effort. Painting a effective, over-achieving Screen onto Drywall is the epitome of DIY Screen making, and warrants doing what it takes to make the surface be as pristine and flawless as possible, owing to the fact that starting with Drywall eliminates so much expense and other concerns and considerations.
