stone floor lifting from adhesive

[vic]

Hello,

A wet floor that was layed 6-8 weeks ago is starting to fail. Several of the envelope cut tiles are not bonded to any of the adhesive(weber rapid set flexi) I lifted a tile using a glass sucker today and it was like cling film had been placed between the tile and adhesive. Any clues at what happened.

Thanks,

Vic

Hi Vic & welcome to TF.

Can you provide additional info please.....
1. Did you tile the floor?
2. What is the substrate?
3. What is the stone?
4. What tanking was used?
5. What method of fixing was used, i.e. trowel size, back skimming etc.?
6. Any pics?

Thanks

Daz

7. Are you a pro tradesman or DIY'er? (no offence meant, it just helps us provide the best advice).

Hi Vic.

What substrate is it ? And what tile type ?

[whitebeam]

Hi and welcome..I await your reply from the questions above..

Were the tiles still wet after being cut?

What Bri said^^^^
Is it only the tiles that have been run through a wet saw that are failing, or all the tiles?

Hey Daz, Thanks for the welcome and no offence taken.

Been fitting high quality bathrooms, wetrooms etc for 5 years. Running my own business, Caliber Refurbishments for 4 years before being taken on by Stone & Chrome in Camberley since the start of the year.

I did'nt tile the floor, no, but I did fit deck, build room etc. The deck was impey, installed in the same way we fit all our wetrooms, no movement evedent. The deck was primmed, tanked with membrane and underfloor heating layed. The sone was a limestone. Solid bed of adhesive used by the looks of it, ie, adhesive was flat from where tile had been pressed down. The tiles were envelope cut and I wonder if the backs of the tiles were wet. some of the tiles i have taken up had no adhesive on the back !!, size being 405 x 610 mm. Will take more pics and forward on.

Appreciate any comments,

Thanks

It would appear so, I didn't tile the floor but was the poor sod who had to go and investigate.

Sounds like wet tiles to me with a lack of back skimming......

I can only assume so. I didn't tile the floor but I think they would have been cut and fitted, will ask the tiller. Can the wet back of the tile cause some kind of barrier that prevents the adhesive bonding to the back of the tile ?

[vic]

The water forms a barrier then ? the fact that zero adhesive was on the back of some of the tiles would make me think he didn't back butter the stone either. Although some parts of the tile came up with adhesive on them.

Appreciate your comments, Thanks.

Yup... the wet back will stop the adhesive bonding to the tile. Even if you back skim it straight after putting it through the wet cutter, it's likely to de-bond. The tile should be completely dry IMO.

The first thing that comes to mind would be dust on the back of the tile, you say it's only on the envelope cuts, so far, any chance of trying a full tile to see if it's the same story.

Edit, also a good point about back buttering, must type faster lol

[Dave]

UFH you say, so this goes over the tray as well ?
