Hi. I've spent long days trying to remove wallpaper in my bathroom. The house was built in the late seventies. There were two layers and the first was not nearly as difficult as the second layer. The second layer looked to be the original wall paper from when the house was first built and literally looked like regular paper stuck on the wall and was extremely porous. It was a big pain to remove it. Anyways, while I was removing the second layer of wallpaper... it seemed to be that the "drywall" was just a cardboard layer with joint compound over area with nails. I've uploaded a few photos to better explain the situation. During the wallpaper removal, a lot of the compound and cardboard wall was damaged. I was going to paint some walls and wallpaper other walls, but I am unsure how to go about this with this type of wall. Are there any suggestions to fixing the problem and what this wall actually is since it does not look like typical drywall... Any help is appreciated! Thanks.:)

would laminate flooring work as wainscot in an attached garage? would it attract moisture and warp? would you attach to sheet rock with glue?, cut out rock and install 1x4 strips, and nail/staple? Thanks Barry
