Happy days :)  👌

 

Looking at the recent reviews of that knauff adhesive, it's all 1 star, they may have changed the formula. That combined with the non primed boards I think I was on a hiding to nothing. It's like an immovable object now with the tile adhesive and I've foamed the gaps between.

 

Even so, I'm going to mechanically fix with screws. Makes me wonder why they recommend stainless screws though when they will be getting coated with tanking anyways, surely they'll spend the rest of their lives dry as a bone.

With SBR + tile adhesive, I honestly think that the screws will do the square root of (expletive deleted) all.
 

I can’t tell you not to fit them as I’m not warrantying the job, plus they cost so little we’d both be fools to not do so / advise you not to do so.

 

So….”do so”. 👌
