Gypsum plaster Weber Saint-Gobain Gypsum Natural gypsum 25kg is 1 bag enough for only 1m2 with 1mm layer?

[Grillen]

I was planning to go and buy gypsum plaster, but I'm starting to hesitate a bit as I see the price and how much one bag covers. Am I reading correctly that 1 bag only covers 1m2 if you apply a 1mm layer? It would be a lot of money if you were to plaster an entire large room. It almost costs the same as hiring someone to plaster with regular plaster in that case.

Or am I reading it wrong and maybe it covers more?

It must be wrong. 1 m² with a thickness of 1 mm becomes a volume of one liter. The bag should be larger.

Thanks for the quick response. That sounds like slightly better figures I simply interpreted it really wrong

No, it is Weber who has expressed himself very strangely.
