Painting limestone basement walls with silicate paint?

So in my case, the interior walls (brick) in the technical room were plastered with lime-cement plaster, for the concrete walls I sanded the rough spots (transitions of the formwork elements), then filled and sanded with Knauf Multifinish. The same with the filigree ceiling. Depending on the requirements, you have to do it more precisely. Afterwards, it was painted with silicate paint from Keim (previously pre-treated with the appropriate "primer"). For the technical room, that is completely sufficient for me. Whether you should do this on damp spots or what happens if you do it, I don't know. I would simply contact a paint manufacturer. This is the technical room; in the living room it is something different again.

Scratch off Stosil and leave the lower row of stones free. When they’re dry, pull the garage floor paint a bit up the wall. Sto Sil white 9010 or 9016. This is a base coat for exterior special decorative plasters and such. It also works well inside; it’s sandy, so there are grains in it. Your wall will look rough then. But it also hides unevenness very well. Sure, it’s raw and like a cowshed method, but it’s not the living room. StoSil wall in our utility room. The gray splash guard on the wall is a PVC panel I stuck on afterward because of the washbasin.

Sorry, his name is sto prim
