Waterproof filler elsewhere

[Syll]

Hello!
I have leftover våtrumsspackel from when the bathroom was built. Can I use it on the drywall in the kitchen?

Hej hopp!

 

[Stefan1972]

Yes, it makes no difference. The differences are still debated........

 

[Ragganof]

Works just as well, just harder to sand.

Why should there be special filler in a wet room?

 

[Ragganof]

Why should there be special putty in a wet room?

In the ceiling, you don't have a membrane, but otherwise, I'm a bit skeptical too.

 

[Stefan1972]

Has anyone experienced a concrete case where insurance companies have backed down because it wasn't used in wet rooms? It is claimed to be more water-resistant, but is there any putty that is?...........Someone mentioned mold-resistant, but why would the putty mold specifically?

There's no doubt that it's more water-resistant. And when it comes to insurance, it can come down to the producer requiring a complete system for a guarantee.

There should be no water in the wall. If the filler is damaged by the water, you already have water damage.

In the wall, there should not be any water. If the water damages the filler, there is already a water damage.

With that reasoning, it would be completely okay with regular paper-covered drywall as well.

 

[Daniel 109]

Yes.

There shouldn't be any water in the wall. If the filler is damaged by water, you already have a water damage.

Yes, did I write something else?

Peter2400: here in Norway these are okay now after the new membrane systems were approved.

With that reasoning, it would be completely okay with regular paper-coated gypsum boards as well.

Isn't cardboard gypsum board approved by BKR since around 2015?

 

[C.Lundin]

Isn't gypsum board approved by BKR since like 2015?

I think it's been about four years exactly.
The agency warns against waterproof boards due to health risks. I'm not well-versed enough in this specific area to know why, but often the warnings they issue are justified. Although sometimes it might be a little exaggerated...

Thanks for all the answers!
