Drywall Cracks, Installed Yesterday


I usually do the drywall work on jobs but this time my boss subbed it out because we're super behind. They finished yesterday but when I looked at it today I noticed tons of cracking. Mainly in corners, which won't be hard to caulk in, but there is a really big one on the ceiling, right in the middle of the joint (not the edge of the tape). I've never seen this happen so quickly. What's going on?

Also, what's the best way to fix it? Can I just skim coat it or should I use some tape (they used paper but I prefer mesh for non-corners)? Should I be worried about something structural? We were replacing their drywall because the ceiling had been starting to fall down, but not in the area of this ceiling crack. We were worried it was termites, it wasn't, and my boss shrugged it off as just old drywall. Also, this crack is near where some of the garage door hardware is attached. Could how they re-hung the garage door be effecting it?

Thank you!

The drywall subs don't know how to deal with it? Why should you fix their mistakes?

I don't trust them to do it right. If this wasn't a garage I would be re-hanging sheets and skim coating everything. It'll be faster to do it right myself.

If it’s a garage, did you think it might have cracked due to a shift in the weather before it was fully dry? I heard mud takes a couple days minimum to dry all the way through and that’s in a controlled environment. Even if it looks dry, it’s not necessarily.

I’m not a drywaller, I Jaws that shlt out.

I've done a lot of drywall in new builds before they are climate controlled as well as other garages and haven't seen anything like this. I'm in Phoenix so we're pretty mild, mid 40s thru low 70s but it did jump up to 80 yesterday.

The joists are running perpendicular to the ceiling crack. Also included an example of the cracking that is all over the place in the corners.

It’s probably because of improper blocking in the ceiling area, every 7 feet you should have blocking in the ceiling Joist. Seems like movement above for sure.

Oh, is that for the additional weight of the garage door?

There were also cracks on the walls, mainly horizontal but also vertical, and I know those studs were at least 24" on center. There's also cracking in every corner, where the ceiling meets the wall and where the walls meet.

Maybe the garage door was operated before the mud fully dried???

Tapes lifted. Watery paint or improper taping. See if tape peels out easily. Do not tape over.

Wow. Somebody’s going to loose some money here.

Re: Drywall Cracks, Installed Yesterday


Wet mud over wet mud and then paint over wet mud ? I think you know where in going with this !

Sounds like one of those ..let's git er done in two trips kinda deals .. with a tail light warranty.
The tape coat has to be cured before the block coat goes on . The block coat has to be cured before the skim coat goes on. The skim coat needs be cured before it can be sanded!

READ THE BUCKET !!

Overloaded mud in the angles can cause the angle cracks. Or the tape was still wet when they coated them ..And when the tape coat starts to cure out under a wet block coat ! It causes the angle to hair line crack in the crease .

It's a garage that's not air controlled ? Where you been man? All garages hung with regular sheetrock go to chit within the first year or so . You can't put regular sheetrock outside !!! It will fail . It needs to be air controlled . It's called DRYwall . If you want drywall to hold up outside? You got to go with W/P.

Re: Drywall Cracks, Installed Yesterday


I think you guys are right with watery mud not curing.

Wednesday I re-taped the cracks (on walls horizontal and vertical, on ceiling on joists and perpendicular to joists, corners I just caulked). Used mesh tape and a thick coat of 45 minute mud then topped it with regular mud. So far no cracking, which is good because their stuff was still wet when I saw the cracks. I didn't remove the old tape but if I have to do more repairs (which I'd bet on) I will.

When I was cleaning up the job site I found a 5 gallon bucket half full with a super watery mud mixture. Much looser than I'd even use in a hopper. More like the stuff at the bottom of your cleaning bucket after mudding for a week. My boss said they were using it to apply the tape (adhering it to the wall and giving it a first coat). I guess they used a normal consistency mud after that, but you're kind of f-ed after a first coat like that. Plus since it was so watery, I'm sure it didn't dry out well enough before the next coats.

I am just totally amazed that people could screw something up so badly.

I'm in Phoenix so our weather is pretty mild and I think that makes a difference. The garages are weatherproof but not climate controlled. Using drywall in them is pretty standard, even the new builds I've done. My detached garage's drywall is 20+ years old and doing fine.

What is W/P? And H/O?
