Hi guys, I bought a fixer upper, and the first thing I wanted to do is tackle the wallpaper. I am new to home repair and learning as I go. The wallpaper is located in both the kitchen and the butler's pantry. I started on the butler's pantry I ripped off the vinyl then soaked the brown layer.. came off nice and clean.. My next move was to tackle the kitchen, and my oh my...I bit more than I could chew.. I repeated the same process only this time, some of the wallpaper have been applied on older wallpaper that was partly torn off. The rest of the wallpaper seems to have been applied on bare sheetrock, although I see some white residue when I was removing the brown layer. I spent an entire afternoon trying to remove the brown layer and the white substance by my finger nails hoping not to damage the drywall. I know I am missing something, and there has got to be a better way other than replacing the drywall... I am attaching few pics in the hope that you can feel sorry for me and share the knoweldge... What is the white substance.. Is it primer ? paint ? GLUE ??? and what is the best way to go ? Thanks guys..
