I’m used to the gummy paste, I scraped off tons of it when we first bought the house, but this stuff really has me baffled. This is the wallpaper on which I had to use full-strength Greased Lightning and put plastic on top for 20-30 minutes before the wallpaper could be scraped off. The biggest problem areas are on either side of the stairs going up to the landing, and the first area I tackled before I discovered the Greased Lightning solution.
Think I’m going to go spray some GL on it and see if that dissolves it.
The GL is working, so, back to work I go!
