Removing edge tiles with UFH

[Timo]

Looked at a job where I'd need to remove some broken tiles at the edge of an existing floor. The tiles are 300mm x 300mm limestone and 10mm thick. On 3-5mm of adhesive with loose wire UFH in the adhesive. On concrete.

So what's the best / safest way to remove the partial / edge tiles without breaking the UFH wire?

Slowly with hammer and chisel

Just have to go careful keep checking the wires as you go.

that was fast!

so do i remove the grout with a stanley knife / chisel as best as I can first? Then just break up a hammer and chisel out? or what about using a cutter with depth set at 9mm to score the tiles?

I'd probably go 8mm, just to vear on caution....

Cutter set at 8mm is probably a good idea. But don't cut the grout with a Stanley knife. As you may cut through the wires .

Try breaking bits out first, then hopefully you will come across the wires.

Multimaster grout remover , hammer and bolster gently , use multimaster carbide plate to sand down adhesive. Worked well for me a couple of times.

Before you start, i would remove the wires from the stat and take an ohms reading and keep a check as you work. I take it the floor is working correctly before you start. Once you have a tile up you may see where the wires are running.
If you are lucky who ever fitted the ufh would have left wire away from the walls by 100mm.
Take it slow and you should be ok.

Good point. Make sure it works before you start . I may not work and you might be blamed for it.
