I would like to know if it is easy to cleanly remove faience (kitchen credence) which is stuck on brick?
It will be very difficult to remove this tile without damaging the brick support, because you will have to proceed with the hammer and chisel of chisel (chisel with wide blade). You can weaken the tiles by drilling holes with a drill and a tile bit.
Other solutions: - tiling on your earthenware by having previously passed a primer after a degreasing of the surface - apply a coating of packing with high capacity of attachment (and after degreasing of the surface), then tiling again - double the wall with a waterproof plasterboard or cement board and tile again.
