Need Help Preping Walls For Painting-Magic Marker, Etc

I am in the process of prepping the walls for paint. I have removed 2 layers of wallpaper of which both top and bottom of the wallpaper were sealed with white paint, I guess, to prevent the edges from peeling. Some of this paint has come off easily with scraping. However, there is still much to much still left on the walls. What is the best/easiest way to remove this? Also, these old plaster walls look like they were used as chalkboards. They have been all over with magic marker. What is the best way of prepping these walls before painting? I know I need to wash them down with TSP or Dirtex?? Is one better than another? Also, which primer is better for this project, an oil based or shellac based primer. Is it Bins or Bullseye??? Thanks

Dirtex is better as it does not have to be flood rinsed like TSP and it is still a good general purpose, pre-paint cleaner. I would sand the paint ridges as best you can and then perhaps skim coat over the area to help disguise them some. If there is really mass amounts of marker writing on the walls, then I would roll the primer over this using either Kilz (original) or BIN. You can also use Gardz as a primer over the residual wallpaper paste, but the Gardz will not work on the magic marker stains.

Thanks very much paintguy. As if scraping wallpaper off a wall is not enough...I got a gallon of Bin primer. I think it will be best to wash off the walls with a scrub brush to remove the paste residue.

Yes, that is correct. I actually use those green scrubbie pads that you use for cleaning dishes on the paste and then big sponges for the rinsing.

PG once again speaks wisely here...!

Also consider the Scotchbrite pads that come with a handle on them for "shearing-thru" the paste/stripper gunk!

If PAINT is still trapping wallpaper?!
* Keep the stripper-solution wet on the wall.
* NOW...get some light plastic and press onto the walls...the ENTIRE wall.
* This keeps solution wet and dissolving paste! Now go out to eat, come back, and start scraping. Only peel back plastic ~1' at a time, while you're moving along the wall.
* Rinse/rinse/rinse this paste off, let dry, and prime EVERYTHING with BIN, Cover-stain, or Odorless Oil...all from Zinsser.
