Drywall cracks easy answer?

[machsnell]

I assume this is from heating the garage and drying out the wood framing but this doesnt seem to happen inside.

I used tape not mesh. It's been done for 5 months and the cracks started showing up about 2 months ago. Not that many but I have only primed so I can fix before I paint.

Wondering what to do?

Cut out and redo?

Can I smear in some paintable caulk and hide most of it and allow it to move? I even glued and screwed the drywall.

looks like who ever did that did not use any tape... if you still have old paint or want to spendy....

use a knife v-groove that crack... also help if you find some area with a lack of screws that the board flexes, screw some extra black screw in on the seams areas...

patch in new tape
feather out
sand
prime
paint.

Do you maintain temperatures in the garage or only bring it up to temp when you go work out there ?

I did the drywall and it has good framing behind the drywall for the header for window.

I screwed and glued the drywall. I installed tape.

I keep the temp between 65 and 72 with pellet stove.

tape and use the hard 90min compound for the first coat....not just finishing mud that always crack.

A lesson I learnt. Never put a vertical join inline with window or door edge.

I dealt with similar cracks and patched as the prior post said using the 90 minute dry mix stuff (after having cracks reappear after having patched previously with the bucket stuff). The 90 minute durabond dries much harder and it seems to have solved the problem (at least for the time being!) I did the final smoothing with the standard pre-mix bucket compound. I think the difference is that the durabond powder is a chemical reaction, similar to concrete, whereas the bucket stuff is just a drying out effect.


Good luck!

mud was probably too wet or the joint gap too big. Contraction of the mud or unsupported mud will lead to that. Mesh tape doesn't help much if there's a big gap behind it, the mud there detaches from both sheets and gives you cracks of its own.
You could caulk it, but that's not the right way. Hit it with (drier) mud / knife again.

When possible....I try to use a whole sheet over the window. If I can't or the window is almost as wide as the sheet, I use 2 sheet with the seam down the middle of the window. This helps to prevent those cracks at seams over king and jack studs.

Thamks all lesson learned on joints near window.

I will cut out the cracks and tape and start fresh. I will use the easy sand 90 and finish with the blue top stuff.
