Outdoor plaster indoors?

[nino]

As a topic, can you use outdoor plaster indoors?
Might be able to buy outdoor plaster cheaper than regular plaster, does it matter if you use it for interior walls?

As the topic states, can you use outdoor gypsum indoors?

No, it doesn't work because they have a coating that can't guarantee adhesion of putty and paint.

 

[nino]

No, it's not possible as they have a coating that putty and paint cannot guarantee adhesion to..

Ok, that's typical ☹️

Guess it can be hard to surface treat it.

Edit: Two on that.

I'll check the price on that, I can actually use it as an intermediate board if I'm going to double gypsum for sound insulation.

Will check the price on that, can indeed use it as an intermediate board if I'm going to double the plasterboard for soundproofing

But they are usually only 9mm, so it won't be the same as a 12-13mm plasterboard..

This was 13mm 900*2400

 

[Plupp 405730]

This was 13mm 900*2400

Ok the question is then what kind of board it is?

Gyproc GEE 13 Ergolite

[nino]

Hmm

Can they be called gple 13 planum ergo 3?

Gyproc GEE 13 Ergolite

But that's not an outdoor plasterboard, is it?

 

[nino]

No, that wasn't correct either...

But isn't that non-outdoor gypsum?

No, I see it...
I only have the seller's ad to go on, and it says outdoor gypsum along with these 2 item numbers
For my part, it's just fine if it's indoor gypsum, then I'll buy them all

Picked up 44 boards for 2000
The one that was supposed to be outdoor gypsum is blue-colored and lightweight, but if you check Gyproc, it's for interior use.
Good for me, but one might be a bit concerned for the seller who bought a new build where this board is mounted on the exterior...

Maybe it doesn't matter much if one was quick with gypsum followed by outer cladding?

Good for me, but it does make you a bit concerned on behalf of the seller who bought a new build where this board is mounted externally...

Maybe you should get in touch and give them a tip...
