I wonder if they use glue in commercial jobs?

1st drywall hanger I see with a caulk gun and a case of glue on one of my jobs will need to remove my boot from his a$$.

I don't really care. I sub drywall work. Why? Because I've also done it.

I either sub it or hang it in house using employee's, but I will not allow my subs or employee's to glue drywall.

I am not hanging drywall unless I get in a bind or have to show slow people how to do it.

After all the great information supplied by AARC and you are still asking why? Obviously if your codes do not let you glue then you can't. If you can glue and choose not to, you do not want the best job and again that is your choice. Is your objection the expense, the time, the strength, the bonding ability or simply arrogance? Because I am your age I'm guessing you are adamant about doing things like you did 40 years ago. At some point you need to be progressive and let go of that archaic thinking. If you think being able to tear off screwed only drywall like toilet paper is the best job, then you are just delusional. I am still wondering if you are serious, because no one is naive enough to believe screw only is the best way, unless they are delusional.

A gain, a know it all who does not have a clue about drywall but needs to try to impress us with his "wisdom". Believe it or not , they are called glue guns and trust me, you will never have a hanger come to your job with glue because any hanger worth a damn would not set foot on your job site. If you think you sound intimidating by the boot in the ass comment, it only proves what a moron you are.

In California we have a screw inspection before taping. All butt joints
need to be 6'' staggered and every stud gets a minimum of 4 in the field
including both door studs king/queen.

In Florida we have screw inspections, kind of hard to pass that when you don't have the proper screw pattern.

Glue would only work here on interior walls, as all exteriors have vapour barrier.

Around here I have thankfully never run into glued drywall, I'm not sure how I would get this into some estimate for a reno. How would you tell before pulling it off the wall? Can't say as I've seen the issue with screwed rock being a poorer finish than glued, but then I've never seen anyone glue it.

You sure didn't come here to make friends, did you Ancient Rocker? Enjoy your stay.

If you install your exterior walls vapour barrier with roofing nails you have a nice spot to put a dab of bulldog.

I pity the guy coming in behind us because we glue and screw all sheets.

Screws on 4"-6" centers down the edges and around the board and every 8"-10" in the field. Over kill but the extra 30 minutes and hardware is worth it to keep the drywall tight to the wall in a small bathroom reno.

For the most part I couldn't care less if it was screwed or glued, all I know is that you get less pops and distortion when you bolt on a big plasma on a big swing-arm bracket. On non structural studs the drywall adds alot of stregnth, the next guy that comes around to hang anything big on thoes walls would appreciate the increase in stregnth and less nail pops.

I have no intention of making friends or enemies, but nothing I have said is a revelation. I merely am questioning archaic building methods that have no place in today's construction. If living in the past is your cup of tea, that's your burden to carry. By questioning proven techniques such as gluing and screwing, you are simply afraid of change. I totally understand you have to meet building codes but if you don't, what do you have to lose by trying? It is very difficult originally to learn how to glue properly and will probably discourage 90% of you because you wouldn't see the fruits of your labor until you master it. I really don't think this opinion will make any one want to change, but I'll argue to my grave that this is the BEST way to hang drywall. When every thing else fails, try logic.

How does it work on rated walls?

Big Shoe

Oops almost all new construction here is framed with metal studs. I really don't know the specs on glue to metal, if there is one.I'm sure I asked my superiors some thirty years ago.

On a few remodels I've tried glueing to metal in some impossible places to reach. Really don't know how well it would hold.

Capt-Sheetrock

That would be me. I don't glue at all, even if requested.. But I've only been at this since 1973,,,, guess i don't have enough experiance to do it ..the best way,,,ahhh I mean YOUR way

Ancient Rocker

Thank you for making my point, Captain. If experience is a factor in doing the best job, then you again are wrong. I have been hanging for two years longer than you and it's all I've ever done. Reading other posts, you are a finisher also.Good for you, but that disqualifies your total expertise as a hanger. And because you have 36 years of experience surely does not mean you are an expert hanger. The man who broke me in 38 years ago hung board for 40 years and his skills were horrendous. I am not saying that is you, but experience does not necessarily mean you are interested in trying to do a better job, but probably a faster one. Because you fell back on the experience excuse, you have again proven my point by refusing to change because it was good enough 36 years ago. By refusing to acknowledge it is a POSSIBILITY gluing is better also supports my position. Thank you Captain.

I suppose the the only downside is that the nail/screw and glue assemblies as described are all illegal in any state that utilizes the IRC or IBC (including Illinois). Per Table R702.3.5, GWB with adhesive still requires screws at maximum 16" o/c for ceilings and 24" o/c for walls so it's basically every truss and every stud.

When you get into rated assemblies (every apartment, hotel room, most condos, etc), you won't find an NFPA, Underwriters (UL) or Gypsum Association (Fire Resistance Design Manual) assembly that allows for such liberal fastener spacing. Even when adhesive is allowed, the fastener spacing still never exceeds 12" o/c.

The fasteners are required for a very specific reason and one that adhesive cannot replicate or accommodate. When an assembly is tested for fire resistance, the applicable standard is ASTM E 119. When placed in the test oven and exposed to flame, two things happen to the GWB that basically provide the fire resitance. First, the water in the GWB is converted to steam and the energy transfer serves to keep the back side (against the studs) cooler longer. Second, the glass fibers added to "Type-X" or "Firecode C" GWB serve to slow down the delamination that occurs as the drywall flashes off it's moisture and begins to char. Otherwise, large cracks and delamination occur (as demonstrated when non-fire rated GWB is tested). The idea is to keep the panel laminated and the gypsum core attached to the wall/ceiling as long as possible. If you rely too heavily on adhesives to bond the face paper layer of the GWB to the stud/truss face, then the mode of failure and weak link becomes delamination of the gypsum core from the face layer. It's like trying to lift a heavy cardboard box by the top flaps while the bottom of the box falls out.

Holy Batman! MacRoadie has simply broke it down. lol Well done my friend.

I never did see how gluing the paper on the back of the sheet to the stud would hold the sheet better than a screw right through it.

I can see how you wouldn't have as many or ANY nail pops. C'mon guys, are we really scared of a few nail pops? I have an empty pocket if anyone is scared.

I would also like to know if I get caught in a tornado all my rock is screwed & helping the structure to hold together as long as possible. Otherwise 's Ova.
