removing plastic tiles
I thought I had an experience that I would never have occasion to pass to another unfortunate victim of plastic tile.
We had all colors, in many rooms. It was stuck on with some sort of nasty, orange-brown adhesive.
Popping the tiles off takes no time at all. But getting that adhesive off the plaster takes forever. You'll need a vicious and viscous remover. I can't remember what we used. You know why? It was so nasty I can't remember much of anything since we used it.
And you'll need a very rugged scraper. Expect to bleed some from the knuckles.
Expect some wall repair when you are finished. We smoothed out the biggest gouges and wallpapered over it. If you are tiling over it, obviously you can get away with less removing and no patching.
In our basement, we popped off the tile and put gallons and gallons of drywall mud over the adhesive rather than remove it. So we have a very rough wall, but hey, it is a basement.
Maybe you'll be lucky and the adhesive will be different, and therefore easier.
Good luck. I need to be picking out a casket now for the early grave that the remover is sending me to.
