I need some advice on how to prep an existing somewhat testured and painted drywall so I can apply a smooth coat over it.

1) what grit should I use to rough up the existing surface
2) is there a primer I need to apply to the roughed up surface before applying the skim coat?
3) Any tips on how to know how rough is enough? Any tips on how to avoid over sanding and damaging the drywall paper?
4) Any recommendations on top coat and thinning needed etc?

Thanks,
Dave

The time spent sanding, smoothing, and cleaning up will greatly exceed just putting up 1/4" drywall over the entire wall and starting from scratch.

If you insist on sanding the wall instead, do not use anything more coarse than 80 grit. After that go back with 150 grit. You will just have to be carefull not to sand through the paper. You will be able to see the paper before you actually go through it. It will be difficult to achieve a very flat surface.

When you are done USG makes a product call "First Coat" that should be used.

If the paint on your walls is flat you do not need to do all of this sanding as the joint compund or drywall mud will stick to it fine. After you have skim coated the wall prime it with the USG First Coat and apply the finish paint of your choice.
