Is This Af200?

[Old Mod]

Hey guys,
It's very rare I'm ever asked to do this kind of work, most remedial stuff is done before I arrive, hence the lack of knowledge!
I'm having to make good a bathroom floor that is failing.
Only managed to get a small piece up this afternoon just out of sheer curiosity tbh,
the rest will come up tomorrow.
So after removing a piece of floor to reveal the Ditra, it turns out it's not even stuck to the floor.
But was it at some point?
Is this the remains of a very thin skim of AF200 or something else?
Any ideas?
Cheers

It looks like it although I've never lifted ditra again after fixing with it. There's a few other adhesives it could also be, F Ball F44 is one that I use more frequently when sticking to timber. (If over boarding isn't possible)

Cheers Pete!
Well as I say it's not actually stuck and both floor and mat are dry with no noticeable residue.
I expected to feel some kind of residue!

Has the fleece come away from the plastic in your pic Marc? Is the fleece still in the glue? I can quite tell on my phone

Certainly looks like a contact adhesive of some sort, you'd like to think it was af200 but, in all fairness it could be carpet glue! You never know! There do appear to be trowel marks in it so whoever did it had good intentions.

Haha good intentions they may have been ......however this is just one problem in this room alone let alone the other 3 bathrooms with catastrophic floor failures already. And only 2 yrs old, all of them!
Could be a long one! Haha

Cheers Bri, a appreciate your thoughts.
Just wanted to be able to have at least some explanation to the client, before I tell him his tray has to come out and possibly all 3 shower walls!
Because of a different issue altogether! Haha

Haha yep!

Ardex say you can lay bite a immediately on AF200 but personally I prefer to leave it 20-30 mins to go tacky like you do with F44. It's even more important with durabase as it curls up and pulls away from the adhesive if it's wet

Cheers Pete! Appreciate that, tbh never used a contact on any decoupler, always used spf!
Still would've expected a little residue tho, don't u think?

When Ditra first came out, I am quite sure the spec didn't specify it to be stuck down as it acted as a floating floor. Something that has changed but that may be due to the better quality of flexible adhesives on the market now.

Thanks for that tho, it wouldn't surprise me if someone still thinks that!
Cheers Tom

To be fair it shouldn't fail because of the Ditra

Should have been a straight forward clad of trav bathroom with Porcel-thin!
With a little attention to a small floor begining to fail. Wet UFH tho, so could be problematic.
Picked a little bit of floor up to have a look see!
Found this to start

They'd had problem with silicone opening up, so called bathroom people back who put 25mm quadrant around gap between tray and wall.
Client didn't like that and has called me in to refit.
Bearing in mind it's two yrs old!
Anyway removed quadrant to find this!
Now I don't usually get involved at this stage, normally done before I arrive, I've been told this is quite bad! Haha

 

[Simon benn Leeds]

Holy......

What gave they tried to stick it down with?...

Doesn't look like contact adhesive to me but looks like it's could be pva? Hope I'm wrong.

Haha no idea, hence the thread!
Tbh it looks loose laid!

 

[Simon benn Leeds]

Water getting behind tray, silicone failing.

Getting under the ditra matting, under tray, warm water dissolving the pva (which I suspect they have tried to install matting with)

Is the floor fixed better at the opposite end of the bathroom ( assuming the water hasn't got that far?)
