Which thin-set mortar adheres?

[Händige_Helge]

Currently in the process of removing a small lecamur/wall that I put against a quite damp nearly 100-year-old basement wall about 25 years ago, installed it with tile adhesive. It's sticking harder than I wish...

Cement-based adhesive?

I also believe more in some fix for outdoor use, than like thin joint mortar...

Some fix for outdoor use I also believe more in, than type tunnel mortar...

Aha, why? I thought tunnel mortar (like Weber M10) was intended for the job? What is the advantage of an outdoor mortar indoors?

Kakelfix is not low-alkaline and therefore unsuitable for lättbetong…

Tile adhesive is not low-alkaline and because of that unsuitable for lightweight concrete…

Thank you. Do you have experience with Finja’s or Weber’s thin joint mortar?
My requirements are that it should be strong and adhere to a plastered wall🤔

Yes, we have done it before, but as I mentioned before, we usually also have wall anchors so that not everything relies on the thin joint mortar...

Cement-based adhesive?

Regular multi-fix, so yes, I used cement-based adhesive for leca about 25 years ago.

Yes, we have done it before but as I wrote earlier, we also usually have wall ties so that not everything relies on the thin joint mortar.

Yes, I've taken the tip😀 I'm thinking of reinforcement once per m2. I'm leaning towards using thin joint mortar from Weber.
Do you know the difference between thin joint mortar and blockfix? Both are cement-based…
