No, but new electrical boxes, opened to check for moisture damage and various other things.
Paint/spackle, etc. are already purchased.
Just read that plywood was the worst for sound, chipboard was better, MDF OSB was in-between..

Wonder what the values would be if you mix thin plywood and thin plasterboard...

Plaster is somehow dried and sanded putty ready for wallpaper or painting.
If you have a bunch of different boards, a bit crooked at the joints, then you put plaster over the whole mess.
But now I might be too young, only 52

Please respect that adding new panels on top of the old ones is not an option.
The question is which material is best to use if you want a maximum thickness of 10mm.
I'll call the gypsum factory and ask them again if you can prime the outdoor gypsum and install it indoors anyway, and then everyone will be happy..

I would at least check up on outdoor plaster. It is probably much harder - but maybe you can live with that. MDF sounds silly. Plywood is quite expensive, but if it's a smaller amount then.. However, as mentioned, you might have problems if you mix materials.
Isn't chipboard available in 10mm?
Otherwise, I also think that 4mm plywood + 6mm renovation plaster sounds like a pretty okay combination. Not that you can screw things directly into 4mm plywood maybe, but then you'll have to drill and use plugs like the rest of us who only have plaster (not my choice not to put wood behind in my house, unfortunately).

Well, not directly. I asked if the panel would smell weird and if it was possible to paint it. He didn't dare to answer about the smell but guessed that I could paint it and have it indoors. But he sounded very unsure. Too bad they are on vacation, otherwise I would have asked to speak with a technician.Danne031 said:
10mm chipboard is available. and chipboard was what handled sound the best too, but chipboard - aren't they a bit too soft? don't dare to mount anything on those?
which board you have on the wall doesn't really matter much against sound and noise...it's what you have between the walls that insulates against noise, i.e., the amount of insulation....as mentioned if you mix boards you will have to live with ugly cracks on the walls and I would consider that a waste.....but tastes differ...

Chipboards work great for mounting.Yrrol said:
I have 12mm ones in my summer house, but still - 2mm isn't likely to make a world of difference

Will there be a chemical reaction if I have two different kinds of boards?trojlee said:
I don't think anything remarkable has happened with the wallpapers other than they have aged here even though they are on masonite. Still, the house has stood completely unheated during winter periods, etc., so the temperature has fluctuated more than for others.
Gah, getting depressed. Bought 7 chipboards and then comments popped up saying it was the least durable and didn't matter acoustically either.
Plywood, hardboard, chipboard, or 9.5mm outdoor gypsum... what do I do... I don't care about the price of these 6-7 boards as long as it turns out well. The hardboard looks so damaged where nails have been driven in. Gypsum has to be plugged and all that... plywood is probably the best at handling screws and other things but what would be the downside of plywood?

But Yrrol, you need to pull yourself together a bit. You've had all possible options described here in the thread, and I also think it's quite obvious that if you want to make a good solution, you should have gypsum as the surface layer. You also found a solution with gypsum as the surface that didn't build more than what worked for you (gypsum+plywood). You didn't want to do it that way and chose chipboard instead. That might also work, but for decades now, it's not a product that's typically used for painting or wallpapering. We know it's POSSIBLE to use chipboard because it was done in the past. Will it be good? It might be good enough.
As for sound, it has been discussed in many other threads. I recall that the cavities in the wall should be filled to at least one-third to reduce resonances, and then it's only mass on the wall that matters, i.e., double gypsum... Since that's not an option: Don't let the wall be empty, fill it with insulation, you won't notice any significant difference between different sheet options.

Okay, I know I'm indecisive. It was the carpenter who became frustrated that I hadn't bought materials, so he went with me and got the cheapest so something would happen. Now, a weekend later and one EX girlfriend richer, I'm torn... It's ingrained that people wrote that plywood splits less, then I've seen construction pictures where they use plyfa, but what I didn't see was if they put something on top as step 2...
I get recommendations that are then retracted, so I get really stressed... best would be masonite so I don't have to worry, and everything would be the same all around, but it's quite a hassle to get boards home, the only seller is closed for vacation.
