5/8" rock tapered recess.

[1990Taper]

I have been noticing some 5/8" rock that has some craptastic variance on the long/factory tapered edge.

I can check it with a straightedged knife prior to taping, and the recess is next to none in some spots. Granted framing will vary from one joint to the next, but it would seem that some of the 5/8" rock manufacturers are doing a better job on their factory edges than other's.

We generally use 1/2" for walls, and 5/8" for ceilings/lids.

The 1/2" rock seems to have a nice and uniform factory edge. But the 5/8" seems to be hit and miss. (Not to mention the bevel on the edge of the rock seems to be cut at too steep of an angle. Resulting in a wider joint.)

The only consistent 5/8" rock I have noticed so far, has large factory printings alongside the tapered edge...

Bevel inconstintency and other problems aren't that uncommon. Sheetrock quality has always been up and down as far back as I can remember. One time we got a load that was 47 1/2". Had to cut the square down before I could work with it.

Hi 1990 Taper,
I had those problems with all of the Georgia Pacific sheetrock a year and a half ago. I tried USG sheetrock from another supplier on one job and the problems went away. My regular supplier, not wanting to lose my account, asked if I would try National (Gold Bond). I said yes, as years ago, Gold Bond was hands down the best rock around (USG a close 2nd). I use Gold Bond now exclusively, my supplier stocks only GB, and I have no problems with "shoulders" on the joints(NIGHTMARE), deep , inconsistent bevels, or that hairy nasty recycled paper on that crap GP board. I was told that I was among many complaning about the GP sheetrock, for numerous reasons.I wonder what the brand is that you had trouble with? GP is best left to the DIY crowd and Home Depot. - unless they change to yet another set of bands on the beveling press! sheesh -
Good Luck

It wouldn't be BGC board, but since this seems like a good place for the story...

The worst board I've ever seen was manufacturered right here in good 'ol WA, and the factory had just opened up. They managed to flare the shoulders up about 2-3 mm - great for that "speed bump" effect. A nice soft core and delivery guys paid by the square meant plenty of damage. Unfortunately, there was no bond between the core and the paper(!!), so you could tear at a small bit of damage and continue tearing across the whole board if you felt like it. "We're aware of the problem. Just bill us." (I was on suncontract - didn't supply materials) Their board has been much improved, but you've got to wonder how some of these guys justify their decision to put their crap up for sale.

CapeTaper.

For me, noone betas USG rock for quality. Ever notice that thin white line just before the paper..I wonder what it does cause others do not have it.

GP....I stay away from it.

Thank you MannyDavis, Capetaper, jasoncring, and Steve H for your help!

It would seem, based upon some responses that Gold-Bond and United states Gypsum are putting out a quality 5/8" product, and that Georgia-Pacific gets the Craptacular rating. (I am sorry, I haven't heard of BGC board. :()

And yes, Jasoncring, sheetrock stockers who drop the rock edge side onto the floor can/will create a "Rolled-edge." Where the paper is separated from the gypsum core. This can be troublesome as it will manifest itself in the form of a seam crack if it is not recognized/repaired before it is taped.

Hello Capetaper. Sorry, I am not exactly sure yet, it was a mix of 5/8" rock we had (for some reason) stocked for ceilings on this last job.

Manny, how many labels do you know of for sheetrock production???

SteveH, you use USG exclusively?

Just for fun, I'm reading a GoldBond technical Bulletin No. 2171 Dated NOVEMBER 1962. (Part of the GYPSUM WALLBOARD CONSTRUCTION TECHNICAL REFERENCE FILE)

Can we petition/ask Myron to setup "Polling/voting" subsystem on this system software so we can easily see what our fellow users prefer/dislike?

Thanks Mark

I had a similar situation long ago with a load of usg board where the brown back paper had practically no adhesion to the core. You could grab a corner of the paper and with very little force pull the whole back off.

I wasn't too dismayed when I first worked with the stuff, since I was sure they would shut down manufacture until they had it resolved (dream on). What really got to me was that they didn't shut down or fix the problem - just kept on going. I finished the stuff, on and off, for a whole summer. Near the end (after pointing out the problems to supervisors and anyone who would listen, as well as backcharging), I placed a call to the honcho at BGC plasterboard and said, "You've gotta know your board delaminates really bad, right?" He said, "I know! I've got an office full of it, but we need to increase manufacture to keep up with the demand!" Gotta keep that money train rollin'....

Sorry, I was just reviewing the code of conduct, and found out that my quote

"It would seem, based upon some responses that Gold-Bond and United states Gypsum are putting out a quality 5/8" product, and that Georgia-Pacific gets the Craptacular rating. (I am sorry, I haven't heard of BGC board. :()"

Might be conceived by some (manufacturers) as Libelous.

I do not prefer one manufacturer over the other's, only the best manufacturer(s) over the others.... Which is what I am trying to determine.

Haven't seen GP rock in many years in the Atlanta area, and glad of it. It was always crap. Have seen variances in other brands too, as Manny stated, which makes for fun hanging when the lengths of one brand are 48" and another are 3/8" or 1/2" less and you need both lengths together in the sme room. Didn't resort to cutting off the square though, just put a few boards on a scrap to cut it. After a couple of houses, cutting the square might have been faster though, in retrospect! All brands have their problems from time to time. Have encountered it with USG, Gold Bond, Weyeyhauser, GP, and a variety of others whose names fail me at the moment. Just something we learn to deal with in the trade.

If you can read this, thank a teacher. If you can read this in English, thank a soldier.

Hello All,
Gee, was in the local Home Depot this week, and thought to look in the drywall aisle. Wadda ya know, USG sheetrock, floor to ceiling, and not a single sheet of GP. Hmmm, maybe they got wise too.
All for now -

The first couple of years HD was in Atlanta, there were a few different brands of board, but USG has been it for as long as I can recall (damn those dead brain cells). There are still issues at times as with any product. I can recall times when backing paper would come loose when the board was snapped back after scoring. Core along the taper wasn't bonded to the backing paper. Face paper rupture with every nail/screw (maybe the core was too hard??). It is as good as it gets, as far as quality control, for the big box stores in my opinion.

A good friend will bail you out of jail. A true friend will be sitting next to you saying, "damn that was fun"!
