Dear forum,
I have some areas in the bathroom with very rough plaster (applied to calcium silicate brick). Since painter’s fleece will be glued on, the surface still needs to be filled and finely sanded. However, I have concerns about using gypsum filler in a moisture-prone room.
What do you think—what kind of special filler should be used here? Something breathable. Ardex offers a wide range of products.
Thank you in advance
