Plaster/patch basement wall and quickly be able to paint with Silicate paint?

[Krille-72]

I don't agree with some that gypsum can't handle any moisture at all. The oldest wall in the basement is in its twelfth year with gypsum and silicate on it, 30s basement with original drainage. It holds well and no visual problems. What was on before was plaster or putty, painted with plastic paint, it had come off completely 50cm up. So moisture does exist there.

I also have a gypsum puttied wall that got 10cm of water on it. I was completely sure I would have to redo the putty, but it stubbornly stayed put as well.

Of course, proper plaster is more durable. But the simplicity and finish that can be achieved make me use gypsum putty despite that.

Gypsum transports moisture worse than, for example, lime plaster. Therefore, moisture migration is better with lime plaster and silicate paint. Walls plastered with gypsum eventually become sticky when the moisture pressure becomes too strong. But of course, you can have gypsum in the basement. You can glue a gypsum board directly onto the basement wall as well. It's all about how much moisture is going to move through the wall. Depending on what the answer is, there are some methods that are better than others. Sometimes it ends up with a ventilated Platon mat on both floor and wall. But the best, of course, is if one can drain away any moisture problems.

But the difference between drywall and gypsum plaster is mold on the paper vs the plaster coming loose and you find out it was a bit too humid.
Quite a big difference.

But we probably agree, really.
But I didn't have the option to wait as long before painting as some said you should after lime plaster.

My point is that gypsum can handle a certain amount of moisture. And if it doesn't survive, it's not the end of the world.
It doesn't mold and takes 15 minutes to fix (okay, 2 hours with mixing, drying, and painting), or you switch to something more complicated but better.
