I’m really struggling to remove the back part of my fireplace. It’s made of marble and stuck onto the wall, which is made of plasterboard as far as I can tell.
It seems like it’s stuck on with a type of adhesive which are placed in big blobs in the corners and middle. It’s quite rubbery / pliable.
I’ve tried using a chisel and a hammer, which isn’t making much progress. I’ve also tried sawing through, but that doesn’t really work either. I’m a little worried that I’ll end up ripping big chunks out of the plasterboard.
Any advice would be welcome, photos below.
