Default Spraying USG primer

I have a big addition project (1500sf) and I need to paint. I bought a Graco sprayer, but maximum flow is 0.27gpm and max tip is 0.015. Here is my question: USG drywall primer says to use a .021 tip and a sprayer capable of 0.75gpm!! Can I spray this primer or is it just going to be a bear?

Would thinning help? Smaller 315 instead of 515 tip?

I want to start painting once tapers are done, next week. Sprayers that are capable of recommended rate/tip are out of my price range.

Thank,
Roger

I don't think that's gonna work. You will need a bigger sprayer or a different primer. 1500sf is not that large...you could roll it out with 18's in very little time, if you must use that primer.

Unless you rent a larger sprayer you'll need to switch primers. Is there a reason why you want to use the USG primer? I've had excellent results with Zinnser Bulls Eye 123.

Bought from Amazon. 1500sf of living space, plus garage is 8000sf of surface! Not wedded to that primer, just want to use a good product, and get good paint results.

I intend to spray primer and then ceiling paint. Then walls, maybe spray, maybe roll. Will spray casing befor it is applied. I want a good surface, I do not do this for a living, I am a homeowner.

Thanks for the responses, I guess I will use a different primer.

I'm thinking that was pretty obvious. Just saying.

The .27 GPM tipped me off. The mod squad must be low on bacon again.
