Removing tile without damaging original tile beneath
Let me start by saying I have no idea what I'm doing, so please be patient. I purchased my first house last summer, a 1938 Spanish eclectic bungalow. Yesterday, I removed a vanity in my (only) small bathroom to find some vintage green and black tile hiding underneath a layer of DIY 80's tile. Of course, I couldn't help but begin ripping out the 80's tile.
The tile is coming up fairly easy, but it's stuck to a layer of cement (thin set?) that is a pain. Underneath that, there appears to be some sort of cloth padding that is glued onto the tile with a gray gummy adhesive.
So far, I've been using a hammer and a small chisel sc****r, but it's VERY slow going. Especially the gummy stuff+fabric+cement stuff. Is there a tool I'm missing? Or a solvent product? Is this something better left to a pro? Any ideas what it would cost to hire someone to remove this stuff?
