We're planning on doing some remodeling soon and have a question about whether or not we can install a 2nd layer of sheetrock on the ceiling? The current ceiling (in this 1950's built home) was installed poorly (with sheetrock running parallel with joists instead of perpendicular) thus causing many sags. It is also a covered with what appears to be a sprayed on texture. Can we just install a 2nd layer of sheetrock over this? Really don't want to have to take it down if possible (thus avoiding having to remove the insulation from the attic and creating a big mess). This remodeled room will eventually become a bathroom. Do we need to use the greenboard type of sheetrock on the ceiling (& eventually walls?) What thickness sheetrock should/could we use if we can install a 2nd layer? Appreciate any insight given!

In getting a room ready to repaint, I decided to remove the wallpaper border that was at the top of the wall by the ceiling . I used sizing under the border before I put it up. When I started removing the border some of the paint pulled off with the paper. The worst happened on the outside walls. It's not just the last applied layer of paint that peeled but goes down to a color I don't recognize as one I painted. This is a house that is 50+ years old. There are a few places where the paint came off below the border but not many. I have a mess! What do I do now in order to get the walls ready for repainting? frustro
