Hello, I am new here and completely unskilled technically. Therefore, I would be glad if you could give me some tips on this topic. Sorry if it is so detailed, but I hope you get a good picture this way.
I want to install a sauna in the basement of my house built in 2013, following the 2010 energy saving ordinance. The basement is insulated from the outside. There are no radiators in the basement.
What concerns me are the walls of the basement room. These are the bare concrete walls, which I painted with exterior wall paint (breathable) when I moved in. At that time, I believed that no sauna would be installed in this room.
The walls naturally have the thousands of tiny holes typical for concrete, which are obviously disturbing in a sauna room. I now wonder how to make the walls a bit more "homely."
The walls are smooth enough; it's just the thousands of tiny holes that are bothersome. The basement is relatively humid. If the basement windows are closed for a few days, humidity rises to about 75-80%. This will not get better with sauna operation, so I bought an electric dehumidifier. It can bring the room (about 25 sqm) back to 55% humidity after 2 hours.
The questions I am now asking myself are:
1. Should I use lime plaster because of the humidity, is there colored lime paint?
2. Is textile plaster suitable for a rather humid room?
3. Do I even have to pay attention to breathability on the walls with paint and plaster in the basement room? Isn't it rather the case that the moisture mainly comes from outside, and everything that seals against the outside is positive?
4. Is there a paint that can compensate for such small holes in the concrete (max 1-2 mm diameter, max 0.5-1 mm depth) so that plastering can be avoided?
5. Before plastering, should I scrape off the wall paint again?
Thank you very much for any suggestions!
