OT Graco Magnum X5 paint sprayer

I think Kilz Original primer recommends a 519.

Even with that tip it needs to be thinned about 10%.

After spraying it should be rolled anyway

I would just roll it.

Edit.

I looked up the specs for the X5.

Don't waste your time.

A 515 tip should handle Kilz just fine without thinning—that’s the whole point of an airless sprayer. It’s not a big tip by any means, so it will be slow, but that may be a good thing if you don’t have a lot of experience behind a sprayer. A 519 tip is likely too big for that sprayer.

That said, is there a reason you’re wanting to use Kilz? New drywall should really get a drywall primer, not just an “all-in-one” primer. Something that has a higher solids content in it to help hide the difference in texture between the drywall paper and the joint compound. Do you have stains to seal on the existing walls? If not, you’re better off just cleaning and running a sanding pole over the walls before applying two finish coats of a good quality paint (from a paint store, not a big box).

Old paint and stains

the drywall I am leaving has old paint and stains on it. I am thinking the Kiltz will give me an even base coat to apply the finish paint on. I am going to use Sherwin Williams paint for the finish. Just not sure which one yet, depends on what they have or can get in stock.

I am going to try and clean the stains off first, but looking at them I doubt they will come off.

I have used an airless sprayer before to spray a metal roof on my old house. I will play in a closet and figure out the sprayer and what to do.

I might do Kiltz on the old drywall and a good drywall primer on the new. The main living area is all new drywall, the bedrooms and such are a mix.

Thanks
