Not sure it binds the alkali element but some latex compounds have resistance to alkaline conditions. Styrene butadiene is used to make latex concretes which have high flexural strength. I don't know what the mapei stuff is made from so not sure. I know it's a type of latex so maybe it's the butaduene form.

Thanks Alan.
I will call Mapei again, but don't hold out much hope of finding out the why's and the wherefore'a, I'm sure I'll just be told 'it just does!' Haha
Thanks again
Bitumen would work yes but a nightmare to apply. I think mma would work as well but would be fearfully expensive and fiddly to work with. Never tried SBR but as that can suffer from alkali burn I suspect that won't work. Acrylic doesn't work. PVA works in large quantities but can take an age to dry and set. Epoxy would probably work but again would be fiddly and costly. A polythene membrane is best for screeds.

You say acrylic doesn't work, and I believe you,
Look at this.

Tried comparing Isolastic with latex plus and struggled to find a difference here too. PH values almost identical.

I thought you pretty much said cement or anhydrate it going to fail and that priming as a blanker isnt that good . So if you said that I stand by what I say if I misunderstood you tell me .

No I misunderstood your post. Who has bought products to market without testing?
I'm afraid not. I don't know why they say a lot of things sometimes. Also to be fair I don't know what it's made of. I suppose it's possibly a numbers game. Put enough if anything on and it'll work. The amount youd need though is just impractical. If it's an acrylic it's a risk.

Agreed.

So your saying they tested it but it's still going to fail

I hope you've quoted the wrong post! 😛
Everything Alan has said I agree with, I've researched this to death over the last week and I have found nothing that would make me conclude a different outcome to what has been said.
He didn't say it was going to fail, he said he didn't know the chemical composition of prime and grip and therefore couldn't comment.
And what he said about acrylic primer not being reliable, is also true.
I've read that myself in the concrete journal.
The only ones that can answer that are Mapei, that don't mean they'll tell me tho.
This is a low end product with a very highly strung installation technique.
Appears to be have been devolved with another market in mind originally, and they've tried to adapt it for tiling.
If you pick a hundred tilers that are not on a forum, how many do you think will have a successful install with this product?
How many will even bother with the installation manual?
This stuff is an accident waiting to happen.
But that's only MY opinion.
Alan has practical experience, and that's why I was hoping he may of been able to answer my questions.
we all know in the real world, that experience far exceeds the knowledge gained from reading alone.
that's what I'm getting at. Who is supposed to have tested what?? which manufacturers and which products?? don't get me wrong I'm not having a go or trying to pick an argument. Just trying to work out what you are actually asking/saying

Sorry I just don't get it . I thought you saying with your chemistry knowledge that even following their recommendations it was still going produce gas and ultimately fail . I therefore misunderstood what you were saying .
WOW!... Great post.. But trust me .. I will be giving these situations ( jobs) a wide berth..jeeees..what is happening to our lovely trade!!
So much prefer the old days... ( coming from an old fart)!!lol..
You guys that deal with these specialised jobs should most definitely charge more.. IMPO..🙂

What about Ardex af, what does that contain and would it bond to aluminium ?

This product is liquid,we use just for fit ditra-mat,is like the glue for vinilin.

Yeah, can it not be used to stick ditra over this surface safely ?

I know it sticks like **** to a blanket on my trowles

Have you been hanging around with Mr Allen?
Looks like we have a winner. Can't see any reason that would not stick. Not sure a primer would be needed but I'd be guided by Ardex on that

How would you use it Alan, would you stick a mat direct to exposed ufh?
I think we talk about some product suitable to fix the tiles direct to the aluminium.
We do some office space over aluminium suspended floor but we use the panels from Uzin Multimoll Top 4 with KE 2000 S
O
Old Mod
Do you level first Ed, or straight to aluminium?
Is the floor heated?
Is the floor heated?
No,we just stick the panels with glue,was pretty god and strong.No heated,you know the floating aluminium panels use for offices

Yes yes understand now, thank you!
