Anyone tried outdoor plaster - indoors?

[Yrrol]

There is 9mm outdoor plasterboard, but what happens if you use it indoors?

I called and asked a salesperson a while ago, and he didn't know if the treatment in the board had an odor, and he said the letter printing goes through the wallpaper. However, he admitted that maybe you could paint the entire board and then use it... With some uncertainty...

Unfortunately, the factory is on vacation now, so I couldn't ask to speak with a technician.

Has anyone tested using outdoor plasterboard for regular indoor use?

I think you'll have trouble getting paint or wallpaper to adhere properly on them since they are wax-treated to prevent moisture from entering them.

However, oil paint adheres well to most surfaces, right?

Why do you need outdoor drywall inside?

strove to get hold of 9mm gips.

Have tested for the same reason as you. Also got the info about the waxed surface. Painted once with cheap white ceiling paint and once with a broken color (egg white) of good quality. However, everything has worked well ... for now, after about a month! Time will tell!

 

[Yrrol]

Yes, regular oil paint or other barrier paints against nicotine and much more should work, I think. Although, I don't actually have any experience painting on wax but...

Now, however, I've bought chipboard instead but it's not too late to change.. heh

Received email response from Norgips Svenska AB:

We have two exterior gypsum boards. One we call GUX (reddish) and one we call weather board (white).

You can use GUX indoors, BUT the surface is coated with a plastic material, which may result in reduced adhesion.
I would think, if you make sure to use a good primer, there should not be any problems.

You can also use Weather board indoors. This board is coated with fiberglass, so you can paint it without problems. It is like painting on fiberglass wallpaper.

the board is 9.5mm... white with fiberglass... very enticing... the question is if it's a successful project though...

How did it turn out?

I'm considering using outdoor plasterboard in the skylight recess, mainly because the 12.5mm plasterboard doesn't fit in the grooves of the window frame, it only goes in about 10-11 mm max.
But I have to be able to do some plastering and painting on the plasterboard afterwards.

I just found fermacell 10 mm fiber gypsum.

It might be a safer bet.

Take a 16mm MDF board and cut it down to a 10mm salnings groove on a table saw. A depth of 12-13mm is sufficient. It's easier to achieve than gypsum. Especially if there is poor support behind the salning.

How did it turn out?

I'm considering using exterior gypsum in the skylight recess, precisely because 12.5mm gypsum doesn't fit in the grooves of the window frame, it can fit a maximum of about 10-11 mm.
But I need to be able to putty a little and then paint on the gypsum.

MDF?

used it a lot in Norway as a sneak when it was supposed to be no list because gux is perfect in the tracks on the windows. turn the backside out. it is a different papp on gux anyway.
