Dittra mat not sticking down - Tile Advice

[marios]

I disagree Marios, It is suitable for all substrates and is recommended by Schluter.

I would have loved it for you to be right Sean,
I spoke to anther tiler friend of mine who said the same as you, so I contacted Ardex technical who told me it is not really meant screed and it don't cope with any kind of water. I told my tiler friend that and his reply was ******** it does cope with water and he suggested I put it I water. I had a sample stuck down by Colin at Ardex technical, it was stuck down very well, I could not take the matting off without tearing the fleece, I then put it in some water for 4 hours and it unstuck very easily.
I therefore cannot chance in putting it in a kitchen because a leak from a washing machine and it all up

Totally agree with Sean Kelly.
Ardex AF 200 is the best solution for fleece based decoupling membrane especially on wooden floors. Easy to apply and ready to go out of tub. Save so much time on preparation and you can tile straight away. Just make sure that floor is completely dry and dust free. 3-4mm trowel plus roller for large scale or grout float or anything flat to press it down and you're sorted.
Good luck...

Yes AF200 is very good and that sticks it down very well,mug it's only meant fir wooden floors and it cannot deal with water. If you say have a washing machine leak it will all come off

Very sorry it should have read 'but it's only meant for wooden floors NOT mug that was the spell checker sorry

For me, X7R is a very rapid rapid. So perhaps its skinned over before its been stuck..

Then you've used other adhesives, so maybe you're mixing it too stiff ??

Thanks for rely, Ardex technical stuck some down and they had the Sam problem

Yes you are right for a wooden floor, but on screed floor it must be totally dry because any bit of moisture will break it down. It's the same kind of stuff we put Altro non slip flooring.
If your laying it on a concrete or screed floo I suggest you use a damp meter on the floor first.
I also suggest you do a wet floor because if the washing machine or dishwasher leak it will break down. I have spoken to Colin at Ardex technical and he is the man who developed it.

 

[marios]

As above. Wet adhesive.

Hanks for your reply it still don't stick

 

[marios]

Adhesive needs to be really wet

Thanks for your repl but it still don't stick

I layer 10 m2 and it all came up with no residue of tile adhesive on the underside of mat

 

[TheAofT]

Ok Marios,
I've been using AF 200 for years and never had any issues with either wooden or concrete floors.
Water ingress will affect anything on floor or walls and if you so concerned about leaksor moisture, there is the only one solution which is complete floor waterproofing like wetroom or swimming pool but at its own expense.
Good luck...

How long did you leave it before you did your pulling up stunt?

How long did you leave it before you did your pulling up stunt?

The 10 meters were only down for an hour or so, I did not want to risk the adhesive going totally hard.
But the pictures above where the matting was stuck down on the paving slab and on the piece of ply, we're stuck down by Ardex technical the previous day, and bought to my site, they were down for about 24 hours and they came off just as easy and leaving no residue.

If just putting 3mm down floor got to be very good
