Hello, a couple of years ago we renovated the basement and plastered all the walls that consisted of siporex. As far as I can tell, it was done by the book with plaster mesh, etc. Quite a thick plaster, I would guess up to 3cm. Now it is starting to crack, especially around window and door frames. It's not that the plaster is falling off but rather fine lines. Can anything be done? I think it's due to settlement in the house that the material can't absorb? Buggaren
