Fibre tape on internal plasterboard corner - stuffed up!

[TCX]

Well there was me thinking I was all prepared, had watched vidoes, read notes (Thanks Rod!) and - notwithstanding the fact that nails just WON'T go in to my studs, was all set with my plasterboarding. And THEN - a momentary (OK, for about an hour) lapse in concentration and I went and used fibreglass tape on one of my internal corners!! Is this a disaster? I know it is not recommended, but what "bad stuff" is likely to happen (this was only yesterday so nothing has had a chance to develop yet!)?

Since I have only put the first layer of basecoat over the tape, can I remove the tape and start again with paper tape? Will I cause irreparable damage to the plasterboard if I pull this tape and first basecoat off? Should I just accept that is going to be a rubbbishy corner, finish it as best as possible with the existing tape, and buy a really tall pot plant to put in front of it?! Any advice, shared experiences, and insults gratefully received (well maybe not the insults - I know I'm a plastering-cretin)

Isn't the learning process "fun" ??

First of all DON'T PANIC. The worst that will happen is in a few yrs it may, I repeat, may crack.

You could go over it with paper tape and just feather out the corner a bit more.

By the way, just how did you manage to crease the tape to get it in the corner. It must have been a real pita.

I like that kind of answer - DON'T PANIC. Very Hitch-hikers Guide! Getting the tape in the corner was no problem - I just stuck one side of the joint down and then shoved the tape into the corner with the broad knife and then stuck the other edge down.

(Oh great - so I can't do the right stuff right, but seem to have a knack at doing the wrong stuff easily - just what I need )

OK, so I'm going to leave it there for now - and keep the plant on call for future problems! Thanks for the reassurance...

Just leave it as is and do the rest in paper. Not every job done in fibreglass tape cracks nor does every internal. Just a large % of them compared to the alternative, paper tape.

Tania, I have done all of the corners in our 13 foot ceiling home with fibreglass tape a few years ago, and they look sensational, and not one has cracked (some will say "yet"). I was not aware that the corners HAD to be done with paper tape, and I did a hell of a lot of research about the plastering before I started, including asking one of my best mates who has been a professional plasterer for over 15 years

If the corners DID crack, I would simply run a thin bead of silicon or something down it, smooth it over with my finger so you can't notice it, then paint over it, problem solved

[rod@plasterbrok]

Alexj66 it is a known fact that fibreglass tape in internal corners has a very high failure rate therefore it is NOT recomended for use in internal corners or ceiling joins.

I also have seen many jobs done in FGT that have not cracked but I have seen an awfull lot that have. It is not worth the risk at any time. Who wants to be repairing walls and repainting after 2 years?

You are fortunate your internals have not cracked but this is not a good reason to advise people it is OK to use FGT in internals.

I appologize about being so blunt, I am not normally critical of any persons posts but this is really bad advice, sorry!

Cheers Rod

Sorry Rod, but if you read my post again you will see that I have simply advised what I did, not recommmended to anybody what THEY should do. This is after all what public forums are for, sharing our own experiences to allow others to decide upon their own course of action.

My comments serve to simply re-inforce your own comment above

Just leave it as is and do the rest in paper. Not every job done in fibreglass tape cracks nor does every internal.

, and to perhaps re-assure TCX that they won't necessarily crack over time, so it strange that you would take such an approach to my post.

I will continue to offer comments based on my own personal experiences, with your permission of course.

Feel free to post anything you like Alex I was not having a go at you personaly.

Fibreglass tape is a DEFINITE NO GO for internals, ceiling joins and butt joins. I have seen plenty of plasters with 15 years experince that haven't a clue what they are doing wrong. It reads to me that you are saying its ok to use fibreglass tape in internals.

I appologise if I have offended you in any way. Not my intention. My only intention is to see that people are informed of the correct way to do a job to avoid problems later on.
