I am not new to the idea of plaster I have had it in homes before..however this new home circa 1900-1910 well there is nice wallpaper (paper backed not vinyl) thoughout the upstairs. I have removed one small 1x1 area and used dif and let it sit for about 10 minutes..it peeled right off with a small wallpaper removal tool...but here is my questin 2 part....


1. What is the white gritty like substance that coated over the area and comes off like mud when it gets wet and could it be all over the wall..and what do i do with it? I'm sure its compound paste but all over the wall?????


2. what are my other options for removal of wallpaper once we figure out what the white stuff is?
