Questions about drywall installation

[Hoffmeister]

Hello.

I'm in the process of installing drywall on interior walls.

Question 1: I read afterwards that the drywall panels should not be pressed together. However, I happened to do this in a few places. I started screwing at the bottom and when I got a bit higher, I had to force the panel against the other panel. It became tight. Nothing broke, but I'm wondering if this could lead to cracks later on or something?

2. Is it common to seal with acrylic sealant or similar in the gap between the ceiling/wall? And the same between adjoining walls?

Best regards

For question 1, I pass, for question 2, I answer ceiling molding against the ceiling and possibly a soft seal between the walls, a thin molding can also be used there but mainly a matter of taste.

Ok! But it can't really matter if the gypsum is tight over like a stretch of about 50 cm, right? It happened to be like that, and when I noticed it, you can't exactly take down the board, you know..

It doesn't matter, just go ahead.

Take a dull morakniv and carve a little in the joint, then let the filler take care of the rest.

1. It is possible to set boards pressed against each other. I have done it in some places at home for the same reason you did, and it hasn't moved any more or less than anywhere else. The only reason it might be sensitive is if you have a house that moves a lot and thereby causes cracks in the joint.
But on the other hand, it's just a matter of filling in with some caulk

2. If you don't really want ceiling moldings, then caulk is what you need in the joint. Personally, I dislike ceiling moldings unless it's a necessity, like with panel ceilings/panel walls where it actually fits in.

2. If you don't particularly want ceiling moldings, it's soft caulk that applies to the seam. Personally, I dislike ceiling moldings unless it's a must, such as with panel ceilings/panel walls where they actually fit in.

Ok, great! But regarding the wall/ceiling seam. Screwed too close to a corner against the ceiling, so of course a piece of the corner came loose.. But I guess it's just a matter of caulking with latex and painting over it then?

 

[Jonatan79]

First spackle, then maybe latex caulk is needed before painting.

 

[Hoffmeister]

Putty first then maybe latex caulk is needed before painting.

But putty first? Isn't it better to smack in a lot of caulk and build it up?

You still need to fill the joint, so add a bit of the gypsum board that has come off at the same time.

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

Corners cracking happens now and then and is nothing to worry about, but as mentioned, repair it with filler. Building something up with sealant doesn't look as nice and is often visible - filler, however, becomes hard like plaster.

You guys are awesome! As always! Thanks for the quick responses!

I recommend the paper tape, read up on how best to attach it before you start plastering.

I used fiberglass tape the last time I built a smaller wall. I thought it was convenient.

The fiberglass tape is fine to use; it has been done for many years.

However, the paper tape is said to be better and absorbs cracks even better in every direction compared to the fiberglass tape.

I used fiberglass on the ceiling with wooden battens above, and it remains as good as new even 3 years later. Not a single crack.
