I have plaster walls in the bathroom, with chick tiles half way down the wall. I ripped all the tiles down (very easy). Then scraped the glue off the hard glue with chisel. Also, some of the section with heating gun. But for some reason, towards the bottom, they putt a lot more glue and its harder to scrape off. Just curious if I could just putty over it? Or will the putty peal off eventually? The glue is hard as rock and porous.
I was told that plaster is more trouble to tear down, so we decided to scape the glue instead of ripping down the plaster and re-drywalling and putting and doing corners. It took me at least 5 hours to scrape it down. But I still have a section about 6 sq ft total that has lost of glue. I would like to put putty (plaster) over it if I can. Or is it best to cut that section out. I was told that the transition between plaster and drywall will end up cracking, sooner or later. Any advise?
