Did the same on my old house, placed 6 mm over tretex. Immediately regretted not doing it everywhere from the start. It turns out great.
I also have a 50s house and recommend tearing down the tretex and replacing it with real gypsum. I tried with renovation gypsum but found it significantly more difficult on slightly uneven walls. Tretex burns incredibly if it were to catch fire, so just that I think is the deciding factor.
hi. why install renovation gypsum? it is much more expensive and gives a worse result if the base is tretex. go with the 13mm gypsum instead. sure, there will be a seam but there will be with the 6mm too.FredrikFiskare said:
now that I've just finished my large: extreme home makeover project, I've mostly chosen 12 mm chipboard. why? well: it costs much less and where I'm not going to hang a TV or kitchen cupboards, plywood is not needed. to hang a mirror, picture etc., the chipboard can handle it. but for the kitchen and where the TV wall is, I've used plywood.
in a garage, etc., it might be the best to go with OSB but it's not necessary. the chipboard takes a LOT of load. regarding moisture, if that's a problem, you have bigger problems than the board in this outdoor room with so much moisture that it would be damaged.
the plywood and chipboard are screwed up with 41 mm chipboard screws or shot with a nail gun 3".

I have just screwed drywall on 70m2 garage walls plus 100m2 upstairs. Upstairs, I have 12mm chipboard under the drywall and in the garage, 12mm OSB.
In the garage, it happened 2-3 times that the drywall screw "slipped" in the OSB board, meaning it didn't hold well. This never happened upstairs where I screwed into the chipboard.

I was also thinking of putting OSB in my storage room. I thought about just having drywall first because it's easier to paint nicely, I'm a bit stingy to have double layers (osb+drywall).
Now I'm considering OSB with fiberglass wallpaper on, it should be a nice and durable surface, right?

It is doubtful whether you can glue fiberglass fabric directly onto an OSB board. There is a high risk that it will come off when you glue it to a "living" material. If you want it to look nice, then plasterboard is probably the way to go.
And how do I best proceed if I don't want plaster on top?
Is it possible to apply coarse filler directly on OSB? As mentioned, it's just a storage room, so the finish doesn't need to be perfect.

Of course, it's possible to both apply fiberglass tape and plaster on OSB. The movements are minimal. People exaggerate this "live material" thing to absurdity. It's not that "live" at all. Just make sure to plaster paper strips into the joints so they won't crack.
Paper strips if I'm only going to rough putty and paint then, I assume?
Do you putty joints and screw holes when applying fiberglass wallpaper, or how does textile adhesive stick to putty?
Textile adhesive should adhere to chipboard, so then it should adhere to OSB as well...

Chipboard strips and filling, of course. It holds up well in a typical indoor environment if done correctly.
