At work the rooms that had extreme temperature shifts we had a dry wall guy who used metal window screen cut into strips for the joints.
I can understand that - for stress cracking - but this is just surface cracks.
As physics go (and that's all I can use since I'm not skilled at this) it seems that the paper allows the mud to dry much slower than the mesh does.
Also I think I might be trying to put too much mud on at once, but I just don't know enough about it to know for sure. I don't think it's a problem and a drywall man might just shrug it off.
I did notice that this batch was a little harder to smooth out than the last batch. It could have been old. How do you know if it's in the 5 gal buckets of premix?
over or under mixed
Premixed
applied it at the wrong temperature
66 degrees F and higher. What range should it be applied? Over that?
or someone had let it dry out, left the lid off, and they thinned it too much.
Nope. Kept the lid tight at all times...and I have no one to blame but me for any of this.
FYI - I talked to the guy that's supposed to be doing this today. He made up excuses for 10 minutes. Gonna look for someone else...unless I get through with it myself beforehand...
Yrs ago the metal bead crimper came out, and instead of nailing bead on we just crimped it, and started with the mud. Well, after having to go back to a house where the kids knocked the bead off the corner with their Big Wheel, we went nailing them on after a few hits with the crimper just to hold it on til we nailed it.
Surface cracks usually come from mud that is too thin. Here's a good one: One time I got a call from a bar owner that needed his newly rocked ceiling finished. He told me he already had it taped, just need some finish coats and paint. When I got there, I looked up, he had the joints taped alright... Duct tape. He left, I pulled the tape off and started from scratch, never told him.
When you get dry wall mud in the 5 gallon buckets you have to stir it before using. They have hand paddles and ones that go on a big half inch drill, and I do mean a big drill, as my half inch hammer drill won't even move in a bucket of mud.

I wonder why they don't write that on the stinking bucket!
The water seperates form the mud. I was also told that if you mix some liquid dish detergent into it it will go on smother for a final coat. It seemed to work for me.

Thanks, Eddie, I'll give that tip a try.
I looked over those buckets last night and through USG's web page and they didn't say a thing about needing to re-mix the mud...but that's another reason I came here: Lot's of good info.
As many tips and tricks as there are here on various things from digging ditches to installing fibe optic cable, DIY would do well to stop by now and then.
