So this is the result of Portland Cement and Aluminium making contact with each other.

That must have been Gary doing the scraping because he's used to working so doesn't need gloves to protect his baby soft hands😉

9 months Julian.

No mate, it's an instant reaction.
I missed an opportunity today to get an image of the contaminated aluminium, kicking myself.
The only piece we saw that was free of adhesive was highly corroded, I got distracted and gary covered it with adhesive, both busy trying to get all the replacement tiles down today, which we did.
For want of a better description, it was like peppered spawling.

A leap into the future and a big lesson for a lot of us I'd say.

 

[Bill]

Are you saying this is the tiler's fault?

Do you have all the spec sheets, dated of course, to facilitate which adhesive to use? (primers too)

Yes

 

[Old Mod]

Do you seriously think we'd point the finger without first checking every avenue?
Tom you disappoint!

 

[Old Mod]

Who do you suggest is at fault then Tom?

Not really, I am only asking questions.

As I have said, I have never laid on the foil faced boards but I do know what clients and manufacturers/builders/shops are like for pushing the job on or materials to be used etc without doing their own due diligence on the subject.

I, for one, am glad you have brought this to the attention of the tilers.

Hard to say without knowing the tiler's constraints on the job.

I am sure you will understand.

Maybe if you had explained your thinking in the first place I wouldn't have been so incensed at your question Tom.
Fair enough.
Believe me, we have researched this to death, left no stone unturned.
We have spoken with every tech department concerned, there is only one conclusion, it's an install error unfortunately.
