I'm re-doing our bathroom. It was last refurbished in roughly the early '60's and so is your typical pink and black bathroom with tile walls. I've removed the tiles using a hammer and chisel. Underneath is a glue that kept the tiles stuck to the wall. I don't know what they used; it's brownish in the color of Liquid Nails, but much less gooey and even sort of dry. In fact, I can use a putty knife to scrape some of it off, but other spots are too hard to do so.
I'm wondering how I can get this off so that I can smooth down the wall to paint it. It doesn't seem to be water soluble. It's too rough and hard to sand, at least with the little electric sander I have (it would take forever and would require a zillion sheets of sandpaper). Paint remover seems to soften it up very nicely, allowing me to scrape it off with a putty knife, but the problem here is at least the paint stripper I'm using costs about $10 a jar and it would take a lot of stripper to completely remove the glue, thus hundreds of dollars. Mineral spirits doesn't seem to dissolve it.
Any recommendations for getting this stuff off? I can't be the first one to run into this situation.
Thanks--
