Hi wondering if anyone could back up my thoughts on paper tape which are that as a builder I ask my plasterers to use paper tape prior to skimming on any areas vulnerable to cracking ie. large ceilings, solid wall to stud wall joints as I have the come back to put crack right and I have rarely seen a crack come through paper tape but I constantly get told by plasterers that it is a waste of time but British gypsum recommend paper tape for a stronger joint so would be interested to hear other plasterers views for and againnst.
 
You're not wrong. This photo from the white book shows paper tape being used. Personally, I've only ever used paper tape for artex and jointing as I've never had a problem with fibre tape when skimming.

I've used it before , works well but obviously more work than scrim . I think it says any gaps over 2 or 4mm should be paper taped ! In other words every joint on house bashing lol
 
It's for taping and jointing as far as I'm concerned.
Actually I find on ceilings that have paper tape on artex ceilings that the paper tape often just peels off.

I agree with British gypsum :bananahappy:
 
Paper taping is what I've always done on new board work but it's much easier to use gyproc white powder fillers to butter and apply than skim. Only down side is the time and really need to let it set before skimming. The scrim by bg are much stronger now and the perfect finish stuff seems to have a tighter weave. A compromise for you and the plasterers could be the 100mm wide scrim

Those tapes needed to be soaked in water but if you didn't then it faileD as too dry.
They tended to be OK until you decorated or over skimmed years later.
There was white and brown.

Are you mainly domestic Pug? I've only ever used fibre but the amount of hassle I've had over the years for hairlines. Even after I've re-screwed joists, fibre tape, sometimes even up floorboards and strengthen joists and still hairline. Going to try paper tape. Skim joint, apply paper tape then skim over?
 
Domestic and occasional newbuild (extensions and lofts). When I say never had a problem, I can think of getting a hairline twice since I've been doing my own work. (15yrs). I've always lashed the pva on and been meticulous with checking for movement in exsisting surfaces. Probably a good handful of luck involved too.
 
I've found that even checking movement etc that if the joists span is not right (Carpenter) then the flex in the middle of the ceiling is sometimes too much. I'm intrigued by the paper tape, I've always assumed that it was the cheap dryline option, but seems i was wrong about that
 
I worked for a firm all we used was paper tape used to soak it in the mixing bath before applying

Paper tape is 7 times stronger than scrim. Most of the time I'll tape up the joints inbetween sets of skimming. I don't do the corners as it's to slow

I've used quite a bit wet and stick paper tape over the last few years but the only problem with it is you have to put it all on the day before.
 
We r going to start using paper tape on all cross joints on plaster boards because it's sucking all the moisture out of the plaster and becoming a pain to get down
 
paper tape is bedded in filler so it has a certain amount more flex than a fibatape bedded to the substrate. If the substrate moves it will crack.
 
So you joint up the day before you skim? And do you need to pva the joints before you skim?

Wet and stick is great on internals. It's a shame it has gone up in price. When the dollar was weak it was £4 a roll if you bought 10 rolls. Now it's nearer £10. Cannot understand why an English company does not make a version. If you try to pull it off when it's dry it pulls the face paper off the plasterboard.

I don't use pva on it if am skimming it the next day. Don't have any problems at all I've even skimmed over is 2 days later
 
Problem with paper tape is if it's not bedded correctly it will peel off like those new build artex ceilings everyone want rid of.

I use paper tape when 2 different substrates meet like new board partition against old and it's never failed or cracked.
Fibre tape cracks on the same joint
So it definitely is better on that respect.
But it's a ball ache and takes longer
