Dave,
The wallpaper project was just about as easy as installing wallpaper in your home. The original wallpaper was attached to the wall well. So instead of chemicals and scraping, we cleaned and sanded the wallpaper then primed over the top with Zinsser primer. We had it already in our garage from another home improvement project. This
paint has high adhesion to almost all surfaces. Maureen and I then rough-cut the new wallpaper and installed it as normal. The true test of any marriage.
After the glue set-up, I used a sharp knife to trim the excess.
I did remove some of the
windows, but not specifically for the wallpaper project (although it helped along one edge.) I pulled both side
windows by the dinette, cleaned the area and window frames really well and applied new butyl tape to seal them. The windows are easy to remove. They just have A LOT of screws to take out. Once the screws are removed and the interior ring is removed, just apply even pressure from the inside to break the seal. I had Maureen outside just in case I pushed too hard.
Once the window is out it made cleaning much easier. Now with the new seals, all is water-tight.
Hope that helps.
Chris
