Retro fit ufh & Hydrogen gas causes floor failure.

Typical companies releasing products onto market without proper research or testing just to make money and leaving end user to clear up the mess .

That not strictly true in this case tho.
They give clear instructions on how it should be dealt with.
You just have to read them and not make up your own interpretation.

So using an anhydride screed over aluminium would result in the same reaction Alan yeah?

So would that translate in to any anhydride suitable products like Anhyfix adhesive, or Anhylevel have the same reaction? Just trying to clarify.




I know you know you're correct, but we can definitely confirm that, through our research we found that a lot of priming methods were ineffective.

Any further info would be helpful Alan, thanks.

I read some articles which stated the only primer or barrier to the reaction was bitumous based,even Silicon barriers didnt stop the reaction taking place , pretty pointless priming with bitumen if you are using ufh, thanks for your help Alan that cleared a couple of questions up Marc and I were considering ?

But according to ajax it would fail even if primed or do the products they recommend not contain cement or andhydrate

How many problems do you have ..
Do, as I did,
place, a concrete panel 6mm. (Without adhesive).
Tape on junctions.
And use epoxy adhesive.
that's no good?
