Problems with peeling tanking

[Chalker]

I've used the webber kit. It's the same as mapei, but a different colour. I must admit, the webber/mapei corner tape is better than ardex. It's a shame you can't get the two combined.

One word, Ardex. Fantastic liquid kit, there really is no comparison on the market currently.

Can I ask what made you take a scraper to it? I can't say I've ever tried to do that, so no idea if that's normal or not!?!

No reason for trying to peel off.just thought I would see how well stuck.bit of a shock.
strange thing is that on sera of wall that had only primer on it ,primer was well stuck to wall.
only after tanking liquid applied and dry could I peel primer and tanking off wall.
you can tell that primer come off as so porous and wet finger discolours plaster immediately

Certainly a bit of a worry!

Try it next time you tank the next day.
this could be just the way it is.mira have not come back to me yet.
been using Mira without failure for 12years or more

Ardex for me as well. Easy to work with and you can start tiling the same day.

Someone else had this problem a week or so ago.. I can't remember which brand it was though, so could be a dodgy batch, or like you say, just the way it is until it's had time to fully cure!?!

There was another thread about peeling tanking, it was the palace stuff and the ideas was over polished plaster, moisture in the plaster etc....

Other thread was me and plaster wasn't over polished nor moisture in the plaster,

I had exactly the same problem as you John, primer peeling off with the barrier paint,
the mega reps told me(used mega after palace peeled twice), "it's the way it is" scraping and pulling in a small area applies a much greater and different type of force than hanging tiles off it, so I trusted his words(maybe stupidly) but all the 8mm glass mosaics are still stuck to the wall, I also left it a few days longer to dry out than manufactures recommendations which seemed to help with adhesion

think youre right .
left the sample area a few more days and much harder to peel off and could only do so when getting a scraper under it.
picking at it after three days could not touch it .
