We are building a garage and have had bricklayers here. The garage is in Ytong. They have used mortar 103 both inside and outside. They have reinforced outside but not inside. The work was done in a couple of days. From what I understand, it is the wrong mortar. What will happen with the plaster in the future and how long will it take before something happens? The bricklayers say they have done this in several places before and want to give a guarantee for it. Can it be redone or should the plaster remain? What do you say about all this, thankful for all help? I can add that they forgot a pallet with render base 133, which apparently is also not for Ytong.
