Is there an easier way to remove tiles off a concrete wall than using hammer and chisel.I have about 120sq/m to remove.

I use an air chisel. But the basic tool is a chisel. Its tedious to say the least. If you have an air compressor of any size, you can get a cheap air chisel from a Harbor Freight" store..

You can rent a chipping hammer with a 4" spade bit. The wall will be clean in no time at all.
