How to treat the wall?

[sepani]

I have a stuccoed wall that needs maintenance. From what I can see, it's the paint that's "falling off". Is it just new paint? And if so, what type? Or does it also need to be re-plastered?

And how can I check what type of paint has been used?

Don't know how to check what color type it is.

However, I emailed Jotun before painting the facade (I have walls painted with silicate paint). He wrote that I can either continue painting with silicate or paint over with Drytech Mur. But Drytech Mur, in turn, cannot be painted over with silicate paint. I continued with silicate paint so I can't say anything about how the result would have been.

But you can't then paint over Drytech Mur with silicate paint. I continued with silicate paint so I can't say anything about how the result would have been.

Large flakes fall off, I take them to the paint store, and they can probably say which one.

Tap lightly with a hammer to see if the plaster is coming off or if it sounds hollow. Alternatively, run a wire brush over the areas where the paint has come off to see how extensive the damage really is. My experience after working on the basement is that there's usually more paint than you think that is loose. Whether or not you should replaster, I would say, depends on how much plaster comes off while you're working. If there are deep pits or if the plaster comes off in large pieces, you need to repair it. Minor unevenness you might be able to live with just painting over.
