I have spent the past 10 months doing a top to bottom, front to rear remodel. For the walls, I followed the directions of others and washed the walls down well with TSP, then rinsed them well, the painted them with oil based Kilz, then painted with a qood quality interior paint. It looks really nice, has been on for about 5 months and so far, so good. There were a few places where even after I did the above, the paint didn't want to stick but after it dried well, it is on good. I removed all the lower furniture and some of the lower cabinets to do this.
I also replaced all flooring throughout. I removed all cabinet doors and drawers .. did a light sanding and then put on a coat of lacquer (it originally had nice cherry cabinets finished in lacquer).
While I was at it, put in a residential refrigerator.
The paint project was a pain.. taping all the little corners takes a lot of time.. bet I went thru 10 rolls of painters tape. There will be a few places behind the overhead cabinets you can't get to easily.
I still have to re-make the window treatments and install new day/night shades.
I'm am almost done and ready to hit the road for the summer.
