Re: Husband vs wife: Stain vs Paint
Hubby's idea is actually more work than just painting. Because you've got so many windows and doors, you'll probably be faster to use rollers and brushes rather than trying to spray. If you spray you'll have to tape and protect everything, with roller/brush you just need a few drop cloths and a steady hand. Hand painting will also apply a thicker coat and force the paint into the pores, nooks, and crannies where spraying only applies a surface layer and leaves behind lots of shadows and dry spots.
Prep the walls by vacuuming well to remove dust and cobwebs. If the wood is really rough, then hitting it with a coarse sand paper hand block to knock the chunks off wouldn't hurt, followed by the vacuum of course. Dirty areas where hands or pets frequently touch will need to be cleaned with either TSP or mild soap solution, rinsed, and allowed to fully dry before painting.
Prime with two coats of a good quality primer such as Zinnser Bullseye 123, use the red label to seal stains. Follow that with two coats of a good quality paint. I prefer Kelly Moore or Sherwin Williams. If Ordjen peeks in here he has some Home Depot fair that he recommends.
