When You Cant Screw Corner Bead To A Stud

Phil

Has anyone else ever run into this problem? I put up the drywall, but when I went to install the metal corner bead, I realized there was no wood behind it, just plaster and lathe. The lathe wount hold screws or nails. I concidered applying some durabond bag mud and trying to "stick it on, but Im not quite sure how good it would hold.

Any ideas here would help, thanks

I can't imagine why or how you'd have a corner with no framing to nail into, but that's besides the point.

If you want to use metal bead, you can buy a corner crimping tool that punches the CB into the drywall. They are expensive though.

Your best bet is to use NO COAT ULTRAFLEX that is a mud-on only plastic/paper tape. I use it a lot in bathroom...no rust.

Although the 'corner crimper' is a good tool, - - it works on drywall, but not on plaster (Greg may have read it a little too fast).

You can use the ultra-flex Greg said, - - or you can use a vinyl corner bead with 3M 'spray-on' contact-adhesive.

use trim tex plastic corner bead and the spray adhesive to stick it on then go back after wards and use a stanley or an arrow stapler and staple every six inches into the drywall and if you really want to make it more sturdy then that, mud and tape the bead to the drywall then use hot mud to bed it in.

I think maybe you read the post too fast Tom . He said he put drywall over the plaster (which would explain not being able to hit a stud). I would suggest tape on corner bead. But from previous threads I'm guessing you guys in the US don't use the tape on bead much. Up here you never see tapers using anything but the paper covered corners. That's all I use. Have gotten interested in trying the trim-tex bead though (have used a lot of their products and like them).

I vote for the vinyl corner bead and spray on adhesive. Ive used this before and works well in certain situtations.

Mudd Dogg, what kind of bead do you normally use? No one uses the straight metal clinch on beads here anymore (although are still available). How durable do you find the trim-tex beads to be. Have used many of their flex beads with no problem (but mostly in areas with no chance of getting hit)..

Phil

DAMN! within two hours I got some really good advice, thanks alot guys. I think Im gonna take you up on that ultra-flex idea. Ill try to post some picks later this week if I get a chance

Wouldn't he just use a longer screw then?

I've seen plaster as thick as 3/4" to 1". If he added 1/2" drywall over top of that plaster and bead is at most 1" wide, he had no hope of hitting the stud. You are stepping back the drywall corner at least 1 1/4" from the stud (both ways). There's no way he could have hit the stud.. A longer screw would have just spun out the same as a shorter screw. Even if the plaster was only 1/2" thick he would have had the same problem.

used in just the way i suggested, it works quite well haven't had a call back on any i've done. But mostly down here in florida we use metal clinch on bead. I have used the plastic a few times and it worked well, but there is a good bit of process to ensure durability. I wouldn't really trust it without the steps i mentioned. I have used the tape on bead before, as it is faster to hang the clinch on i found it a pain when matching up corners for windows, tray ceilings, etc.

Mike Finley

Yep, my votes for the 90% of the other trims available that don't require to be nailed on. Simple is as simple does.

Tom R

Gotcha, - - you're right, - - my 'air-err'!!

Thanx for your reply Mudd Dogg, I always used to use the clinch on beads for speed as well (as did most tapers up here). But on most of our drawings in the last 4 or 5 years, it's been spec'd we have to use tape on. More of a pain to apply but I do feel that the coat of mud under them and the tape as well makes them more durable. I guess I have no choice (the drawings tell me what I have to use )!! Thanx again..

Is stapling the corner bead on with 1/2 staples a huge no-no? I think that's what the plasterers up here in the Boston area do (mesh type bead of course.) I may have just answered my own question

JustRightCo

Am I mistaken but I recall using a roll of drywall tape with metal flexable inserts. comes in 50ft to 100 ft great cause you could always keep spare
corners with out taking up the space. No nails or screws just mud to attach

JustRightCo

picture made buy stanley

theworx

What, don't they sell just regular tape on corner beads. That flex stuff is like three or four times the price. Great in a lot of situations though (off angles etc...). I just can't see him buying a whole roll of flex bead to finish one corner. Tape on paper corner beads is all we're using right now, and have been for years if you can't get them where you are, opt for the trim-tex corner.

3M glue will work on metal corner bead if it is clean

Phil

Ive used that stuff before and I didnt like it as much as the flex. Im comming across more of these situations as I excel more in this job. Like I said, Ill post some before pics once I get a chance so you can see more what Im dealing with. This is a hige 4 bedroom 3 bathroom house, and Im the only guy hanging and finishing it
