Hi, I have walls in our casa which have been skimmed in Yeso, up to 60mm with two thick coats and one thin skim to finish. The walls are in a bit of a state with patches which have blown, so I intended to remove all loose Yeso and repair with Yeso. I then intended to pva bond the Yeso walls and apply a finish coat of capa fina throughout. I have no experience with Yeso, so I am hoping that someone with more knowledge can confirm if my approach is correct, as I don't want any issues with the Yeso substrate later on. Many thanks.
