New Ceiling!

[Olympus]

I finally put in the ceiling in my 30x36x12 shop. I used 1/2" osb, smooth side out, and did it myself with my wife working the drywall jack. I have zero carpenter experience and the job was tough. My arms are sore from using the big nail gun and my neck is sore from constantly looking up, but 2 days and it's finished.

After I finished, I've had people tell me I should have staggered the **** joints on the sheets. Seems like it's too late now. Is this a huge problem?

When I get ready to finish the walls, should I stagger the joints there?

No big deal with the lack of staggered seams. That's important for drywall to keep a crack from propagating, but you're not going to be finishing the ceiling to that high of a level anyway.

Wow, nice big shop you've got !!

Presume that this is detached garage . . . right ??

Looks like you've got some rough electrical going, so don't forget to plan out potential 240v runs for compressor, welder, lift, etc before everything is closed up. Also put in LOTS and LOTS of outlets, you'll be glad you did later!

While you're still open stud, you might consider in-wall airline system made from black pipe steel or copper with the main trunk up in attic, then with drops down on various walls in shop. Pressure test everything while still open stud, and you'll be set for life.

Good luck planning and completing your shop.

Yes, that's a detached metal shop. 30x36x12.

Got lots of outlets already. I think 18.

use lots of screws per truss, at least 6. i just did mine a few weeks ago with 4 screws per truss and some sections of the osb started to sag. i'll see if i can post a picture.

BTW, i had take a 2x6 and jack to push the sagging parts up and add 3 or 4 more screws per truss. also i used 7/16 osb.

He nailed it! I'm a screwer myself. The newest generation of drywall screws is much thicker/stronger than the old ones. They don't shear off even as you countersink them in the OSB.

Yes to stagger but it's not worth ripping down that ceiling to fix it.

I didn't have any problems with sagging. I used a preacher board occasionally to get the corners up snug, but that drywall jack smashes those sheets flat and tight. I put 4 ring - shank nails across the trusses in the middle of the sheets and at least 8 nails across the sheets on both ends at the joint.

I had to climb up to run a little more wire and the sheets would easily hold my weight, 200lbs. I tested this very gingerly until I was confident of their strength.

+1 that ring shank nails will do the job on ceiling, assuming you don't ever want to take some of those sheets down.

For walls however, I sure would use screws as there may be changes in future that you'll want in that wall - - ie add electric run, etc.

When I put the walls up, should I go ahead and stagger those joints? Also was told that I should run the sheets horizontally on the walls for added strength. Any truth to this?
