I would say gluing is a great extra step if all you're doing is nailing it, but I would venture to say the the vast majority screws their rock here. As for the expansion and contraction bit, I can't help to picture what happens to vinyl siding when you set the nail tight rather than leaving it proud for movement. Wouldn't the glue inhibit movement and cause cracking if you're bonding two materials that are subjected to movement?

Vinyl siding is the one doing the expansion and contraction. The drywall is pushed in and out, thus creating nail and screw pops. Ceilings are the topic, but I would glue all drywall. You will never have an issue if you glue.

On the West Coast I have never seen drywall glued unless spec'd or high end residential. Screw/nail pops have never been an issue...

JesseCocozza 12-25-2011 10:55 PM

I understand that. However drywall is subject to expansion and contraction just like the wood that you're attaching it to is. I'm just asking if there might still be cracking. The nail pops in my opinion is a simple enough fix... Eliminate the nail and use a screw instead. I agree that the glue might be an added step to ensure a secure install but whether it is nessecary or not is the question? This mentality of "what can I do to make something better?" is commendable but it doesn't mean that someone is receiving a sub par product if the rock is not glued. There are other factors involved including the quality of the finishing, so it's hard to conclude that the glue is solving all the problems.

Its like why even put rebar in concrete. That suff dont move.


If you have never seen a screw pop you are blind or havent been in trade to long.

I have never seen it glued on in Ny either unless it is an overlay or for acoustics.
If it catches on in this area i will be a nightmatre doing remodels as everything that is built anymore will be rebuilt again & again. I think this is why M. Holmes screws all of his framing.

I was told by a good source that he screws everything because even he makes mistakes and that changes do take place and they are easier to take care of this way. Lol.

Ok forgive me on the screw pop bit, obviously we've all seen them. However I've seen less screw pops than I've seen nail pops. I'm not saying that gluing is bad. I'm saying that it's not the end-all-be-all. It's not common practice here. We've all seen the pops and cracks. We've also all seen perfectly fine walls and ceilings that weren't glued. I'm suggesting that there are more variables in the equation to make a statement like " if you glue it, you won't have any problems."

I'll bet I've been in business longer than you are old.

Never said I haven't seen one, Eye Doc just gave me 20/20, just never been an issue.

There could always be problems with glue or material from factory defects. Doesnt mean you dont do the extra step to make a superior product.

Who or what is pushing it in and out?

Are you familiar with the theory that many nail pops are caused by shrinkage of new-construction framing? I find the concept quite persuasive, and to be honest, don't recall experiencing pops to any extent when re-hanging on existing "aged" framing.

Here on the coast of Virginia, we always "tack" with smooth cement coated drywall nails. Then go back and screw off.
Granted, sometimes I wondered about the lack of screws on walls, but maybe thats why I didn't have much problems with pops.
I built over 50 homes, used mumerous crews, watched hundreds more homes being built and never once did I ever see, on plans or in practice, glue being used.
Not to say that it can't be used. You can can overbuild lots of entities and hope the appraiser gives you credit for it and hope you can afford to sit on that house because it won't sell because it is overpriced. Something to think about when your whole world revolves around the sale of that house.
On another note, an old timer once told me; not to "over build" things, as they may have to be dismantled at some point. He was 70 and he and his family had been building (Framing) homes their entire life.
5/8'-If you are going to use it on walls, be sure the windows (that were ordered and set long before) have the right jams. And order your interior doors accordingly.
Here, we use allot of one coat plaster and "Blueboard".
Two coat plaster was used on wood lath and 2'x4' drywall with no tape.
The blueboard has no different qualities except a blue coating is applied to help the plaster stick.
The plaster we use is "blocked in" and let set, 1/2 hr. (covering the mesh tape), then applied with a trowel at about 3/16", feathered at doors and windows and "sponged" to an attractive swirl pattern. Kitchens and baths get smooth.
This costs about the same as "Drywall" and 200 board homes can easily be plastered in one day. Some people prefer this finish for its harder surface.

Has nothin to do with how long someone has been in business just doing something that will give you a quality installation that stands the test of time. No matter what trade.

It's not an inferior product if it's not glued, it's just the way some of you prefer to do it.

Like I said before. It's not common practice here, so one could assume that cracks and pops are also not as common. Therefore, if you see structure that might subject drywall to cracking or popping, wouldn't the "superior" task be augmenting the structure to resist movement? That might be too time consuming or costly, so we'll just glue the drywall. Problem solved. That's how I view it. It's a band aid or duct tape to mask a bigger problem. Is that problem your's? Not unless you framed it. So point those things out to the GC or homeowner and deal with it on an as needed basis. Don't tell everyone else that they're lazy hacks if they're not dealing with the same circumstances.

Glue does not make a quality drywall job. If you can't make it come out right without glue hire a pro...

I'll bet our lumber out here has the same moisture content as yours...

And if we are talking metal framing....:laughing::laughing::laughing:

You'd be in business about 2 weeks out here. And do not even start to preach that superior quality crap...

If you can get away with that & convince people that glue makes your drywall job superior....you are wasting your time in the trades...

I bet there are a bunch of Eskimo's that need AC units....:laughing:

If glue is not needed for a ceiling etc... Then why is it spec'd for a "high end" residential build?

Not always. The spec I have seen, is how I have stated previously.
5/8" board over 5/8" plywood, both glued & screwed & the plywood edge blocked. This is for a large expanse of that dam no texture smooth finish. I just do not like that look.

Wasnt just talkin about drywall with glue and material. Talkin general about any trade has differnt methods of products.



:laughing::laughing::laughing: Metal my bread and butter.

Tech Dawg 12-25-2011 11:50 PM

I think a lot of the confusion is due to building codes in different states, municipalities etc... Some places, your ceilings are required to be glued... Roughly in a 20x20 basement, your talking under 30 bux in liquid nails or loctite to glue a ceiling up. I just always looked at it as extra insurance :shrug:

griz 12-25-2011 11:53 PM

Aw heck, it's all good.:thumbsup::thumbsup:

I've just been around little kids all day, fueled by candy, & have been enjoying copious amounts of Christmas cheer. Day started at 5AM & I didn't have a nap today.

Best wishes to all you guys this New Year....:thumbsup::thumbup:
