Crack in tile - Advice please

madeinireland_2

I had a kitchen fitted before Xmas. As part of that a new floor was laid with underfloor heating. Have just noticed a hairline crack in one of the porcelain tiles across the corner about 4-5 inches long. Almost invisible at this stage. Not sure if it has just appeared or if it was always there.

Any action required or suggested?

Thanks...

Normally you can pop one out and replace.


But not with underfloor heating as it will rupture the cables.


Your best option is to get it repaired by some one like The Magic Man. (google them). They fill them and spray them. You would never know it had been damaged.

Usually hairline (or bigger) cracks appear because the screed/UFH and tile aren't in unison. Do you know if your screed was fully dried out (may not be relevant if you've just replaced the kitchen and not the floor), or that the installer used a lining under the adhesive (Ditra or similar). If not, then the tiles suffers stress due to the UFH temperature change. Sadly there isn't much you can do as replacing the tile will not cure the problem.

It was fully dried out for sure. I waited weeks before switching on and gradually built up the temp.

Thanks - sounds like a good option. I think I will probably wait until it's really visible. At the moment it's so fine even if you did see it you would thinks it's a dog hair. I sort of figured that replacing it would be difficult with the underfloor heating.
