Opinions, Yeah Yours

Ok, the guys that work for me got into an argument or maybe just a simple disagreement on the right way (proper pattern and number of fasteners per stud) to fasten drywall to a 16" center wood stud wall.
I told them I would let you guys settle it. I've always used 7 in field (one top, bottom and center, then two close together halfway between the center and top/bottom edges, 8 on the ends. Thats how I had them fasten it. Is that over kill? They both had much less, but different patterns

We screw the ceiling rock, 4 or 5 in the field + edges. Walls are nailed 5 per stud. Just us.

jproffer

Assume you mean hanging horizontal?

Walls: from bottom up...zero, 6", 18", 30", 42", 48" (obviously zero and 48 are not really zero and 48....just close to the edges, then 6 away from both edges, then a foot 2 times in the center.

Ceiling: zero, 8", 16", 24", 32", 40", 48"

and No I don't measure it, just eyeball it like everyone else in the free world.

Yep, One top, one bottom, one middle, one in between...on ceilings with 1 5/8" screws

Walls are one top, one bottom, two in between... 1 1/4" screws

That's what everyone around here does, it may be different somewhere else.

These are in the field only......On butt edges, we are every 8-10 inches

I always used 12" spacing in the field and 8" spacing on the ends. that seams to be the norm around here. I don't change any of the spacing for walls or ceiling. I just use bigger screws on ceiling or 5/8" rock.

I've always used 3" screws, the longer length has better holding power so you dont need any in the feild-just one in the top and the other in the bottom....saves time and money. If your hardcore you can get away with using adhesive on each stud and only using 1 screw at the top...the shear weight of the board will press itself into the studs/adhesive so no bottom screw is needed...but applying adhesivve takes time and extra money for cases of adhesive so I only do that on high end jobs $1M homes and up, the rest is just 2 screws per stud-even on butts.

3" Screws ?, Aren't You Worried About Hitting Wires/pipes That Might Be Running Throught The Stud Or Joyce.

IHI......... Do you realize this is why we (in Iowa) have a reputation for being contractors that don't deserve the right to be called contractors???

Or did you finally pass that test??!!??

maj

No, Joyce is in the other room...

IHI

LOL, Redman your right!! I never gave joyce a thought, now it's adhesive only for me.

Just like I'll never understand why roofers nail down shingles when they could just as easily use the peel and stick method by removing the clear strip on the back side....you boys make too much work for yourselves.



















Oh, this is'nt april 1 anymore is it

OK, I have seen the method I described at the begininning of this thread used many times here in the Southeast. I always use screws.
Always run it horizonal. However, If I interpeted the code correct it does say, 1/2' rock. 16" centers should be no less than 8" on edges and 12" in the field. Just doesn't seem to be enough.

IHI, great. Now I have to deal with you trying to make beer squirt out my nose !! Keep it up!!

theworx

If you are running horizontal and you say the code calls for a screw every 8" on the edges (I'm assuming you're talking the bevels) I will also have to assume that you are either using a lot of backing material or that the wall has backing framed into it. Is that correct??

Redman

no, 8" only on the non beveled ends of the sheets. Bevels edge will only be screwed off every 16".

Sorry man, my question was directed to Dayspring. Just want to clarify what he's posting. Not looking for advice (I've been boarding for 20 years). By the way you are correct in what you've said in this thread .

dayspring

Redman is correct. However the USG website suggest it nailed every eight inches, everywhere for walls and they do also suggest double nailing, especially on ceilings. Reference:

Thanx for clarifying (had me slightly confused, which is easy to do , when you said 8" on the edge). To me the edge is the bevel and the butt is the end. Our code requires a min. 2 screws in the field and every 8" on butts for walls and three screws in the field and every 8" on the butts for ceilings. We are required to use screws (no nails). Our usual way of doing it.

Have had inspectors request that I double screw my ceilings too!! A little extra work but I tack that on as an extra.

Do you guys float your butt joints (with a backer) or do you cut your sheets to hit studs and joists???

mistersmooth

Has anyone ever put a screw in thier leg while hanging drywall? Um, OUCH! You kind of have to un screw it to get it out. Double ouch!
