Hello.
I have chipped off all the plaster on one side of my chimney (indoors) and replastered it with Finja KC Putsbruk B.
I have also raised an iron stove that was connected to the chimney where I had to rebuild the flue (Combimix refractory mortar)
as well as raise the gables using bricks and Finja murbruk B.
How long must this cure before I can plaster everything with gypsum?
