Hello,
Similar questions have been discussed in the forum before, but I still need some advice.
We have a wooden house from 1923 (100 years Hurray!) with a classic foundation wall made of solid granite blocks. The previous owner painted it with some type of plastic paint. We would like to revamp it to look like the pictures attached. We have removed the old plastic paint. In one room, we tried priming and plastering with plaster mortar. We chose to follow the shape of the stones to maintain the feel. It looked incredibly nice but was completely useless, a knock and the whole wall comes down, completely hollow so it probably didn’t adhere due to many different handling errors. It’s been torn down now.
Anyway, what should I do instead? I'm thinking of filling the gaps with smaller stone fragments, and "grouting" and then painting with lime paint? Does that sound reasonable? What should I grout with to avoid seams between each stone block? Or should I attach fiberglass mesh and try to plaster again (once more)? Or fiberglass mesh and lime paint, is that even possible?
Help🫣 definitely don't want to use plasterboard, I prefer to keep the feel. As a last resort, we've considered building with 70mm lecablocks and smooth plastering. I would be so grateful for ideas 💡

Try applying primer twice on a small area, then mix the lime mortar to a watery consistency and apply it with a gråsugga (large brush) so it becomes like coarse sandpaper on the wall. Let it set for a day and then plaster with lime mortar, the so-called sandpaper ensures that the plaster stays in place, giving it something to grip onto.
Answer no, as I haven't needed it in the house, but others have used primer for stone that doesn't absorb. There's a bit to choose from. https://www.google.com/search?q=primer+icke+sugande+underlag&sca_esv=559711199&ei=JFTnZOL8LoWExc8PwduRmAU&oq=primer+icke+&gs_lp=Egxnd3Mtd2l6LXNlcnAaAhgCIgxwcmltZXIgaWNrZSAqAggAMgUQABiABEj8TVDBE1j1LHABeAGQAQCYAYwBoAH_C6oBBDEuMTK4AQHIAQD4AQHCAgoQABhHGNYEGLADwgIGEAAYFhgewgIIEAAYFhgeGArCAhEQLhiABBiLAxioAxikAxiRBcICCxAAGIAEGLEDGIMBwgIREC4YgAQYiwMYkQUYqAMYpAPiAwQYACBBiAYBkAYI&sclient=gws-wiz-serp
