Evening all, hoping for a little forum know how. Ideal Standard basin installed four years ago and the glaze had crazed. Ideal supplied a replacement without demur, ie must've been a bad batch. Went to swap them over, easy Friday afternoon job etc. but the basin has been so securely stuck to the tiles with silicone that had I forced it off the tiles and probably the plasterboard would've come with it. I tried to cut it with a long blade but it was a tough as old boots and I tried to fashion a kind of cheese wire with a bit of earth wire from some t&e but it wasn't strong enough. I was a bit wary of using hacksaw blades or my alligator saw. Anyone got any fool proof tips? The current plan is to source some spare tiles before I have another go. Thanks.
