does the tile adhesive need to cover the whole tile

[Unregistered]

I am in the process of having my shower tiled. The plumber has left for the day so i have been to see how it was looking. The tiles we have chosen are quite big and looking into the gap between the wall and the tile i can see the adhesive has been applied in about 6 blobs to each tile. I was under the impression it would need to cover the whole of the rear of the tile. there are large gaps where there is no adhesive and i am concerned that the only thing keeping water out is the grout. surely if the grout were to work loose water would run down between the wall and the tile?

Dot and dab, bad code of practice. Grout is not waterproof, just water resistant ( unless epoxy) I would advise you to, register as Doug sugests and post some pics if poss

Dot & Dab is a BIG no no

100% coverage in showers

Why is it a big no no. Will it leak?

Tanking is also advisable but maybe its too late now.

I think its too late now. I was suprised they didnt but they assured me it didnt need doing. I didnt know anything about tiling and took their word for it. Im obviously quite concerned now that we might be storing up trouble for the future. Am in the process of speaking to the builder who brought him in to finish our extension

Spot and dab is not the correct way :yikes:

As Diamond above, register and get some pics on. You will get top advice for free, the members on this site are passionate about tiling. We hate to see bad working practice, It tars the whole industry with the same brush. This guy is no tiler, and should be stopped now:mad2:

What adhesive was used, tubbed or powder, not that it makes any difference though

tubbed

Water will soften the adhesive, stop him from proceeding.

 

[faithhealer]

very important you stop him from continuing. As you correctly assumed, if water gets through the grout there is nothing to stop it going where it wants. Tubbed addy is only good for 3/4 mm thick otherwise it stays soft. I have found addy thats been on for months and still soft.

The tiles could be too large for tubbed adhesive too.
