Which smooth plaster for interior use?

Now I have to replace the plaster retroactively on almost 300 sqm of floor area....

As long as the cement plaster was completely set (dry), nothing happens at all. Only if the substrate - here cement plaster - had a residual moisture content of more than 3% before applying the gypsum plaster, it was not a good idea (the sulfates react) Rhineland greetings

Only with stubborn clients ... There are recommendations for a reason to observe drying times Rheinische greetings

I am with you - but probably very few do. Unfortunately, for the builders the word "warten" is usually erased from their vocabulary, especially in the final phase. Especially the turnkey providers with their advertised short construction times hardly know any real drying phases.

I'm with you on that - but probably very few actually do. Unfortunately, for builders, the word "waiting" is usually eliminated from their vocabulary, especially in the final phase.

Sure, but that doesn't change the fact that gypsum simply does not react to cement plaster once the substrate has set. If this misconception is constantly repeated, gypsum – a well-established and reliable building material – gets a reputation that it does not deserve. A prime example is gypsum plasterboard walls – far better than their reputation, especially in terms of soundproofing – yet many builders keep parroting the nonsense from the internet.

Especially the turnkey providers with their advertised short construction times hardly know any real drying phases.

Builders can ask, read, inform themselves? It takes two to tango; it’s not always the fault of unscrupulous providers. Besides, in this sector of the construction industry, the widespread use of chemicals exists.

Gypsum has no place in construction - my opinion as a client.

For most suppliers, of course, the ideal material because it is cheap and easy to work with...

And I only know chemistry as a drying accelerator in screed - is there such a thing in plaster as well? But whether that is the be-all and end-all? No idea, as a client I would do without it.

But interesting how they immediately refer back to the client - otherwise derided as an ignorant layperson, but then he is supposed to deal with drying times? In the final phase? Probably few do that...that's why many also build turnkey, to hardly have to think about it...right?
