......... But there is also another issue. Say the original coating was breathable, micro porous or whatever. The pva has formed a seal over this stopping the original paint from working. A build up of moisture trying to breath out could blow the coating off the wall.

I am still not convinced any pva should have been coated onto the wall. But if this is the issue it will be a real pain trying to sort matters.

That's how I understand it. The masonry, render and original paint will more than likely been breathable, the PVA has now stopped it all from breathing.


Also, stabilizing solution is deep penetrating where as watered down PVA will have just sat on the surface.
