Help! Advice needed tiles on ply

[Amos78]

We're in the middle of tiling the whole ground floor, hubby is not a pro but is capable lol well .... Because the front door entrance there was an issue with the level of the floor , to make it level we tried levelling stuff, but there was another problem with the entrance , anyway it was uneven, so he tiled in the hallway and kitchen by making the bed extra deep. Then as we were using too much adhesive he decided to use ply 6mm but we didn't know that was a big no no. I'm scared that they are gonna come up, so half the hallway and living room is done with ply underneath, obviously concrete is under that. We are doing the rest of the lounge with an extra thick bed as we are obviously too scared to carry on. He won't pull them up and start over, he won't do it He used a semi flexible adhesive and flexible grout will be used once finished. How screwed are we guys? I'm so Angry and worried

Can I start from the beginning, did hubby just lay the ply on screed floor to get a build up.

 

[Amos78]

Hi, thanks, he laid the ply on the concrete which was underneath the original flooring, but yes he did it to get a build up.

Just to clarify Whitebeams question, how is the ply attached to the concrete floor? Glued? Screwed?

 

[White Room]

As you stated 6mm ply is a no no, there's every chance it will cause the tiles to move inevitably crack any grout that is applied.

Do you have pictures to verify.

 

[Amos78]

Yes, this is why I'm posting for help

Did he fix the ply down or just lay it and tile over it ,

 

[widler]

Looks like he has dotted them as well

 

[Amos78]

What's does dotted mean ? No he screwed them down. And please we are new at doing this we don't know the jargon. He honestly didn't know about the ply, he's tiled before but never needed ply and when they said harder backer board at 6mm he assumed the ply be ok.

 

[Amos78]

It's glued and screwed the spacers are 3mm

 

[widler]

Sorry Amos , it looks like he has put blobs under the tiles instead of spreading the adhesive on the floor with a notched trowel, it leaves voids under the tiles and they can come lose , and if you drop owt on them they will crack

Were your tiles fitted with dabs of adhesive like this

 

[Amos78]

Widler he did spread it out , sorry is spreading in on the floor with a notch trowel

 

[Amos78]

No not like above , we are still laying them. Spreading on the floor.
