Dot & Dabbed Porcelain tiles - job in progress

[arc]

Gents,

After some advice here.
Pics below show the state of my kitchen floor this afternoon. The work has been done by a checkatrade registered tiler with good feedback.

The floor has 3 areas, at either end is a concrete floored extension with original wood flooring in the central part.

The floor was PVAd, then covered with a flexible adhesive then Ditra matting to avoid movement issues between the substrates. The surface was then covered in self levelling compound.

The tiles are 40x40 wickes porcelein tiles and the adhesive is wickes flexible porcelein adhesive (after a change from the Mapei rigid adhesive which was used for the first few tiles). After I requested a flexible adhesive we lifted the tiles and cleaned them off ready for the wickes adhesive.

As the new adhesive is rapid setting the tiler has now switched from a trowelled application to a dot and dabbed method. Looking around on the web I've seen countless threads criticising the dot & dab method and claims that british standards rule against this method. Any suggestions welcome...

If the tiles do need to come up - is the adhesive likely to pull up the SLC / Ditra?

Afternoon, quite a few issues you have there. The PVA is a big no no, an acrylic primer should have been used. You also really need to have an expansion joint where the two different substrates meet as ditra only helps with lateral movement, this can be done using a Silicon to match your grout so that it is not noticeable. Finally dot and dab is not a recommended method of fixing tiles, I'm being a bit polite, it is a totally unacceptable fixing method. If you do decide to take the tiles up there is quite a high chance that the SLC will come with it, possibly the ditra also.

Im afraid that Bri is bang on. That is a terrible installation! PVA is not suitable for any job in a tiling installation.Please have a read through the link below

Regardless of this, I doubt that floor will last more than a month or two. Every adhesive has a max depth, it looks like he has exceeded this depth but more importantly, you need to get 100% coverage of adhesive under floor tiles (I dont need to point out that you dont have that on this floor) otherwise they crack, split and come loose. All it takes is a table leg or some1 wearing hight heels.

Please do me a favor and contact Check a trade and tell them that you are not happy, this is what they are there for. Im sick to the back teeth of hearing about people being ripped off by cowboys.

Oh and needless to say, dont pay him a penny.

I think the floor will probably be okay as long as long as you don't walk on it!

I can't believe the installer has knowledge of ditra mats and SLC etc but chooses to dot and dab, he's the one who will get the dreaded call that the tiles are cracking which means he's seriously out of pocket.

You say he had good freedback? He's not from one of these My Builder sites is he?

I am gobsmacked..!!!

That is atrocious , no support on corners etc.. you should really SLC the floor before installing the uncoupling mat.. but that method of fixing is so so wrong and a failure is deffo due..

You need to stop this installation now and confront this so called tiler and say that this method is not providing 100% support/coverage to your tiles and that he has not followed BS5385 fixing methods..

I have had to put right a lot of work carried out by tilers that have been rated really high on check a trade (including a lady that was getting electric shocks from the shower), every time I ask "have you got hold of check a trade?" and they always say "oh no, I dont want to make a fuss". Please do not be one of these people, give him a bad review and make it very clear to him and to check a trade that you are unhappy with it. This guy will continue to rip people off if nobody starts to give him bad reviews.
