How to get boards straight on a wavy wall?

[seniorkonsult]

Now we are discussing the BBM (BKR) post above point 5.7.1. Then, one can nitpick words, and I previously mentioned that it went too fast, but regardless, it is what is written that applies according to the mentioned point. I quote it again because you do not want to read and instead focus on old text. "Gypsum boards with cardboard should not be used in wet zone 1 as a substrate for waterproofing and tiling or as a backing board. Wood-based boards should not be used as a substrate for waterproofing and tiling. "

No, karonggips should not be used in zone 1. But that doesn't mean karonggips can't be used in wet rooms.

BBM is well bKR and references to industry standards apply as I understand it. Now, I have not currently read up on GVK, but it's wet room control, and the requirements should be similar?

No, the requirements are not similar, as GVK has never prohibited gypsum board as long as the waterproofing supplier approves installation on gypsum board. Most waterproofing suppliers allowed this, but after pressures (which are not about damages but rather about economics and politics), many installation instructions were changed.

When building a bathroom today, one can choose between BKR or GVK and follow a set of regulations. Both are correct and fully insurable. If you choose GVK and the right waterproofing supplier, the bathroom is professionally executed, and full compensation is given in the event of a wet room damage, just as if it had been built according to BKR’s regulations and waterproof board.

I have always only claimed that it is allowed according to GVK and nothing else, as stated.

No, plasterboard should not be used in zone 1. But that does not mean that plasterboard cannot be used in wet areas.

Plasterboard can in fact still be used even in zone 1 as long as the correct regulations are followed and the waterproof membrane supplier permits it.

Yep, my mistake!

The thread according to the title has been lost long ago injonil. You have the right to have any opinion you want, but instead of insisting on being right in hair-splitting matters, I believe it's better to be certain and make a good wall. I think it was a woman (Annie Must?) who worked at the largest gypsum factory who several years ago went public saying gypsum should be banned. There were a large number of insurance claims. We are still talking about ceramic cladding. Even if it's approved to use regular gypsum under plastic flooring, I believe it's a big risk since damages often occur due to leaks via fixtures and clips that have come loose, and perhaps only we here in the forum have a clue about such things and address them.

It is still not okay with rolled waterproofing or ”rubber” as waterproofing on wooden joists. According to GVK's industry regulations, wooden joists should be equipped with plastic flooring as waterproofing or waterproofing membrane on wooden joists.

Here is an article page 1. Aime Must was the name. http://www.wigstrom.net/pdf/gipsskivor och krypgrund 070621.pdf

Lolle; so you have to search through the regulations (which change all the time) if you want to save some money and risk having to redo the entire bathroom?

Senior troll? Or just a muppet?
Stop spreading misinformation just because you have to assert yourself by being right on an internet forum at all costs.
Read the different sets of rules and learn from them. Or take a shortcut and listen to, for example, Lolle who knows them inside and out.
