Our en-suite bathroom has got underfloor electric heating and ceramic or porcelain tiles on top. Been down about ten years and "we've" decided that we want new tiles on the floor.
I know REALLY to do a proper job that I should take the old tiles up but if I do that the chances are I'm going to damage the electric u/f heating cable and it'll end up a) a bigger job and b) a lot more expensive.
So the Q is, will it be OK to tile on top of the existing tiles. And what, if any, difference will there be in the performance of the u/f heating? Oh and if it's relevant, the sub floor is chipboard flooring on top of the rafters.
Any recommendations as to tile cement or tips or things that need to be done like scratching the tiles with an angle grinder for a good key etc?
