Installing OSB and Drywall

[snowjim]

Now it's not like putting up a painting or a shelf when you're screwing on plasterboards. The screws should hold the board in place at different temperatures and humidity. It's stingy to screw as sparsely as you've done. Redo, do it right.

I don't need to redo, it’s enough to complement as stated in the manual. It says, first place 5 on the long side then complement.

Redo I don't need to, just need to supplement as it says in the manual. There it says, first put 5 on the long side then supplement.

No, that is absolutely not possible. If you don't screw all the screws at once, the drywall can self-ignite or explode:eek:

I didn't mean with "Try again, do it right" that screws in the drywall should be removed, but rather that you should go back and add what’s necessary so it's correct before you plaster.

It has proven really difficult to get hold of acoustic sealant! Ahlsell has it, but I don't have a company to purchase from, how do you usually do it? Right now, I have installed all the boards with about 3-10 mm gap to the adjoining walls, floor, and ceiling. So, I probably need to fill something in, but I could also use tec7 or something similar just to fill.

 

[thomas33]

Why should you fill the joints? Normally, you install ceiling and floor moldings that conceal the joints.

Latexfog is cheap and is what is usually used in practice.

Got the AKUSTIKFOGMASSA SIKACRYL-S 300 ML from Ahlsell with the company card Now it's time to supplement the boards that are already in place with sealant and screws.

Wait a minute, sealant in the joints?
Why?

Yes, after filling and before painting in the ceiling angle and corners...

No, the drywall screw goes through drywall, OSB and into the stud if done correctly

here's the thing. OSB is not good to screw into at all. A little movement and you no longer have a threaded hole, but basically a smooth hole.
The colleague's six-year-old son can pull screws off it with his little hammer.

Acoustic sealant might give a hint?
Probably overkill unless you want to optimize the wall's soundproofing properties, of course.

Acoustic sealant might give a hint?
Probably overkill if one does not want to optimize the wall's soundproofing properties, of course.

Don't think that sealant makes any difference.

 

[anders07]

Acoustic sealant might give a hint? Probably overkill if you're not looking to optimize the wall's sound-insulating properties, of course.

Sure, but not with OSB behind the drywall, that's money down the drain!

 

[cpalm]

Yes, but not with OSB behind the drywall, that's money down the drain!

The sealant should be used in the floor, ceiling, and wall-wall angles where the OSB and drywall do not overlap.

 

[twoody]

The sealant should be used in the floor, ceiling, and wall-wall corners where the OSB and plasterboard do not overlap.

What benefit does it provide?
