What plaster to use for plaster ceilings-concrete panels, and walls with autoclaved aerated concrete. The walls and ceilings are flat enough not to use plasterboard.
I plaster the aerated concrete with a solution of 1 part cement, 3-4 parts sifted sand, 4 parts of caustic lime. Then the finishing layer.
I have plastered with Volma Plast mixture on the aerated concrete.
I really did not like the Volma Layer! It is "fine-dispersed" and therefore sticky to the trowel, in addition, it is more expensive than Volma Plast.
If you do not save money, take Rothband, it is guaranteed to be good plaster.
