Spray painting interiors?

[Mitch Kronowit]

With any luck, we'll be closing on another rental property this month. The inside desperately needs to be repainted (no surprise), but I was thinking about spraying the interior this time rather than logging another 25 miles with my paint roller, especially since I will probably have to prime AND paint. If there's one thing I hate more than painting a wall, it's painting it twice.

I'm thinking about simply hitting all the walls with my airless sprayer, but I'm not sure if this is more trouble than it's worth. The popcorn ceiling is in decent shape and I can probably leave it alone and the carpets could probably stay after a good cleaning, so what's the best way to prep the area for spraying? Obviously I have to cover the carpets very well, but what about the popcorn ceiling? Can I cover it with a "drop" cloth? Should I simply jam a spray shield in the corner where the wall meets the ceiling and carefully cut in the edges? I'm looking to pick up a paint brush or roller as little as possible here.

I have an organic respirator and some good goggles, but is there anything else I should consider so I don't become another "Tim Allen" statistic? Perhaps a paint hood and bunny suit?

Thanks BP team!
