Questions about drywall installation

[Björn Melander]

Ok, I see. I have 70 mm insulation now = more resonance?

No, as long as the insulation is not compressed, it's ok.

You should use either paper tape or fiberglass mesh tape in the joint between the boards, so use that and build up the damaged area with filler so it covers as much as possible. After that, use flexible filler in the joint as usual.

Corners cracking happens from time to time and it’s nothing to worry about, but as mentioned. Repair it with filler. Building something up with caulk doesn't look as nice and is often visible - filler, on the other hand, becomes as hard as gypsum.

Finished drywalling yesterday and cracked another corner... I have OSB underneath as mentioned. Can I just fill up the damaged corner with filler? No risk of cracks? It's a hole about 2x2cm between two drywall panels... just fill and sand it evenly, right? The filler will be against the OSB underneath. Is that fine?

Just keep plastering.
