my corners are cracking when hanging drywall in the ceiling, why?
 
My corners, some, not all, are cracking when I put the drywall screw in.

Now that I have the crack, would that be covered when I do the taping with mud and sort of "build it up" to make it even?

How can I avoid this?

Thanks

You are probably getting too close to the edge. Then when you drive the screw in the material breaks. Try staying further away and on edges angle your screws into the 2 X 4. Also, you might be driving them in too deep. If you want to be safe, use dry wall nails in problem areas.

Ayuh,......

And be Gentle with the drywall between the lumber yard,+ your jobsite........
Just loading,+ unloading on the pickup can be 'ell on the corners.......

Another Idea is to start your screw pattern in the Centers,+ work Out to the corners.........

And make sure the rock is tight against the stud before you screw it in. Corners have a tendency to get caught on things. Then the screw forces the rock to crack. Taping will more than likely fix the problem though.

Thanks for all the suggestions.
Will try again.

Nice to know that the mud will cover them all.

Everyone's given you great info.

My wife's comment is that mud and sanding will corrrect just about any mistake so long as you don't have a lot of protrusions sticking down through your ideal plane.

Keep in mind that gypsum board is just two pieces of paper with 5/8 inches of packed gypsum between them, nominal. So this heavy 4x8 or ideally longer if you're doing ceilings is pretty fragile. And if you're doing ceilings you are probably using thinner thickness. I always use 5/8 on everything because my brother in the trade would dis-own me if I didn't listen to him.
If you're breaking corners, stop doing what's breaking corners. Your load is carried by your field screws. The corner screws are pulling the least amount of load. Coated sinkers would work for the corners and the mud and taping will transfer the load over the entire field when you finish. We're all looking forward to your finished project. Good luck. Cliff

Thanks Cliff.
I'm also looking forward to my finished project.....whenever that will be :laughing:

I'm just starting to realize that I can move the screw away from the corner.
I was thinking that a lot of weight was being held by the screw in the corner.

Thanks for the info.

I'm looking forward to mudding as I have a considerable amount to do.
(I have cut the pieces of drywall in pieces in order to get it up to the ceiling) (16 inch strips-if you can believe it.)

So I have a lot of mudding to do.....:eek:

I think you ought to re-consider the ceiling. :no: Hire a couple of college students for an afternoon to lift them up for you. Make a 2 X 4 "T" to hold them in place while you set the screws, starting in the center and working you way out as previously mentioned. :yes:

The amount of finish work, taping, sanding, matching etc will be far less and the finished product will look much better. :wink:

you could choose not to screw close to the edge for the ceiling at the wall/ceiling intersaction... keep it "float" and support by the walls. but the internal pieces you should screw all edges. if there are cracks... yes there are more work... you need to empty out the cracks with cutter and stuff and fill in fast drying mud compound... a step not required for good dry wall...

Thanks for the advice.
But, I have had offers to hang the drywall for free, but for me right now, it's a question of seeing if I can do it myself.

Yes, I will have a lot of taping but that ok.

Thanks K. But can I just use regular mud to fill in the cracks, and do I really have to clean it out.
Can't I just leave it the way it is, and then try to fix it with mud?



Thanks for your advice.

KUIPORNG 12-18-2007 09:59 AM

the proper way is clean it up... as it will be bumpy look otherwise because the crack will make the surface not flat no more... but then if the crack is really minor.... it can be ignored by just tape on top of it like it never exists.... so the answer is really depends on how severe is the damage.

Do it yourself....with a lift
 
You can rent a drywall lift for about 30.00 a day.....then crank it up as slow as you want....and if your cut is too tight, you can slice a little more off. I did this and was able to install 12 footers completely by myself...though I kinda hope you cannot lift a 12 foot piece of sheetrock.....the point is you can be slow and meticulous to get it just right.

KUIPORNG 12-18-2007 03:43 PM

here in Canada is no 30.00 a day...it probably double like 60 a day.... things are redicularous expensive in Canada.... don't know why... even our dollars are high these days....

mt232 12-18-2007 03:57 PM

I got lucky, they cannot chanrge for Sunday in my town....so I really get 2 days for 30.00 as long as its back by 9am Monday
