Hello. I am going to plaster two interior walls of lightweight concrete (multiplattan). A total of 17 sqm of wall. I'm planning to use Finja's thin joint and thin plaster mortar A, directly on the lightweight concrete.
I'm thinking of applying it in two layers, totaling about 6 mm.
Does this need to be reinforced with fiberglass mesh? Feels a bit like overkill?
Best regards,
Helge
