My porcelain kitchen tiles are lifting - help.....

[d8wyt]

We put down 40sqm of porcelain tiles in the kitchen. We have under floor heating which we commission for weeks before the floor was laid, we used flexible adhesive. It begun to lift a few months after it was laid. The tiles lift then the grout crack. It has only done this in parts of the kitchen not the whole kitchen. Please help as we had it fixed and it has done it again so would like to fix it permanently!!

Thanks

Welcome along to the forum. Could you give us a bit more info, such as the brand of adhesive, is the UFH piped or electric, was the grout flexible, did you run the floor temp up gradually after the adhesive and grout had been given time to fully cure.

Hi..

What substrate is it.?

 

[d8wyt]

I can take a picture, but not sure about lifting the tile. Yes we did gradually heat the floor up. It was a flexi adhesive and grout we used but unsure of the brand as we have used it all!! It was laid on ply floor.

Piped!

Substrate..?

Sounds like the ply is the problem again.
Bounce? movement at joints?
Was it screwed down properly etc?

 

[d8wyt]
