I’m watching the guys I hired to hang “rock” (drywall) in a house, and they are glueing and screwing, but using many nails also, should i stop them from using nails?

Only if you want one in your forehead.
The nails are the easiest way to start a sheet. Screws are great as is the glue but the nails are the quick way to fasten the sheets when you can't get the screw gun in the right place or you are holding with a hip and a thigh and can't negotiate a screw gun at the same time.
If it bugs you check the nails. If they are in a stud all is good. It is the ones that miss that cause the grief. (for that matter the screws as well) Just tap the ends with a screwdriver and you'll feel if the fastener is home or hanging in space.
Bout the same answer .
They actually hang the sheet with nails in the perimeter. The feild gets the screws . All the nails should be covered with tape . See?

Thanks for your input, well appreciated, resting easy (with screw driver in hand of course ;)
One thing I don't really get that I've been hearing lately is the glue thing. What does the glue do on paper? MAinly the issue I have with glue....and I'm assuming they use liquid nails or PL is that if the rock ever has to come down to be recocked down the line for one reason or another theres these globs of hard glue on the studs. OK OK so maybe they wont ever have to take down a board you say yet I have and so have you all. OK so maybe its no big deal..just don't get the glue thing.
BE well

Makes more sense on on ceilings than it does on walls to me . Of course it gives walls shear strength. My add on the walls is that it doesnt hit low studs giving a straighter wall, but of course the studs are placed there for support to nail to, so the arguement. Glue and screws on walls is over building.
Tim Mooney
I agree with you Tim, but much depends on what the builder specs. Ceilings are a must in my book, simply as a CYA for the hangers. Walls don't ussually get glued around here unless the builders says to. I don't know if there is an additional cost for glueing walls.
I have pulled dw off that had been gluedon remodel jobs, but that is ussually because I am taking out ths stud wall or a portion of it in most cases. Re using the studs is a problem, but the tareout is not much more difficult than dw w/o glue. Most of it goes in the dumpster anyway, so I don't consider it a problem.

I have done it for a long time and it has let me think a lot about it mainly because its my job. This is a full veiw of how I see it ;
Nailing walls is fine with the glue acting as tightening shims of course with adhesive. Thats really where nailing alone fails in that it busts the feild around the nail before its able to be pulled up to a low surface. Of course the result of that is loose nails for ever showing through. Glue provides a floating system of highs and lows to be blended together with about a 1/4 of an inch tolerence. Screws alone will take the rock to most all of the lows but leaves a wavy surface in some walls. I think Jeff Buck said about hanging cabinets ; "No wall it straight regardless of who built it. " The main reason that backs his statement is that the studs will move before and after they are attached. Straight studs picked for a kitchen wall are no longer straight at a later date. So the compromise is to live the best we can with the "high- low effect".
To me slightly nailing walls over glue and then scewing off later is the ultimate , but nails well placed are very effective also. A myth remains to day that nails pull loose . Mainly they were never tight, or were a partial miss.
Of course Im speaking of exellence in theory , but money is the ruler .
That was my Stanley thermos thoughts at Breaktime. LOL.

Okay..Okay.... If you staple paper faced insulation to the face of the wall stud or visquene (plastic) to the face of the wall stud to act as a vapor barrier ,then your glueing the paper of the drywall to paper or plastic on the wallstud . Anybody ever take off a piece of drywall after this procedure was used ?

Dont ever do that .

Good Friday to ya T.M. Just trying to be politicly correct when stapleing insulation to the face of wall stud , never done it that way but read somewhere that the little "V" that is formed when you staple the paper to the side of the stud is a no no something about "air channel,or not allowing insulation to expand properly" may have read it here at breaktime. It kind of reminds me of one of Boss Hog's Quotes " according to my calculations the problem does not exist."
Kraft face f/g insulation is joke as a vb IMO. If you are going to use f/g bats, then use unfaced, and a 6 mil poly vp. Personally, I like Mike Smiths wall system for insulation, vb, and the ability to true the wall with shims and strapping. Unfortunately not many of my customers are willing to pay the extra cost of his method, no matter what the payback.
The vb question has been beat to death here, but in relationship to drywall and glue, what is the point in glueing to poly stapled over studs? If, as Tim suggest, the glue acts as a shim for the low spots, then that would be the only reason to glue over a poly vb.
What say you,Tim?
He said it already. He said, "Don't do it." That would be a silly practice. glued and screwed, while certainly stronger, sholuld be limited to cases where there is no separate vapor barrier. ie It's OK where spraying foam, or blowing cellulose or uninsulated spaces. Or strapping over whatever insulation and vb is used.
Even more satisfied then before, thanks again Tim and all. I went back looked closer, and they nail the perimeters only and screw the field. More confidence in my helpers.
