        Help… my plasterers say they cannot apply lime plaster to our Porotherm blocks without the plaster cracking. This was selected a) to be our airtight layer and b) to be breathable. They say if they damp the wall down all the plaster falls off.

        Should I change the plaster, change the plasterer or daub the walls with PVA? Other suggestions I have had today include applying Roman plaster or a ultra high polymer specially developed parge coat both sides (which may not hold the plaster either).

        Suggestions gratefully accepted…

          I can't see why it would be an issue. I'd ask Porotherm and get a rep on site if your plasterer is struggling
