It is my first year teaching and when I got into my room today, I noticed many posters from the old teacher (she left the school) were still up. As I started removing them, I noticed everything was hot glue gunned to the walls! Most of the walls are painted brick but a few were not. Anyway, some of the glue would not come off by peeling it. She even hot glue gunned a stuffed monkey to the wall and I had to cut it off. SOme of the fur is still on the wall since the glue did not release! Funny but it looks horrible! I was wondering if a razor blade would work to get this stuff off. It is such a mess!
