Taped joints all failing in new house?

Steve I wasn't talking about you mate that was regarding Joe 90 ,yes mate you may have your preferred filler but we have used Easi fill by the bucket loads as well as Lafarge gear and others
Wonder text may be good but never used it pehaps a regional thing

Well Mr plumber sorry about that I thought u was referring to my post I apologise , but next time u have a job try joint cement you can use it to snag shallow areas for painting or use it for jointing in combination with filler, if you think how easifill is easy to rub down joint cement is half again as easy

Easifill is way overpriced. Joint filler is a better product at a fraction of the cost.

Joe joint filler is used in conjunction with joint cement its used to bulk out the joint it doesn't work on its own, if you was to use it on its own you would never get a good finish and it would take a month of Sundays to sand down as its not made to sand down just bulk

Easyfill is overpriced rubbish. I find Wickes plasterboard adhesive to be far better at a fraction of the cost.

Leave it to the pro's Joey.

Well- update.....have done the upper bedroom- retaped using the scrim and Wickes ready mixed jointing stuff, all went pretty well needs a bit of sanding but not much- all internal corner work. I reformed the entrance into the utility room using metal corner strips but this time used Wickes "patching plaster"...reading the blurb they say this is good for a final finish and to be truthful I find this kind of plaster easier to work with- it's stiffer than the jointing stuff and more like rendering, but ideal in terms of workability (!!!), but I find I can get a better finish on it with less faff. I've also found using the jointing stuff that pulling off the old tape, replacing with scrim and going over it with this stuff is very difficult to get a good finish. It also seems to shrink a hell of a lot- the ambient room temp is 12-14c not putting the fire on yet...The OH isn't too happy about me using the patching plaster, but I've discovered boards that have edges with nothing solid behind them so nothing will ever be perfect- she's going on about getting the whole ceiling skimmed(waste of time and money IMHO) but I've done a few bits in patching plaster tonight over the scrim tape that we will sand down and paint at the weekend to see if it'll do the job....
The baffling thing I discovered is the failed tape in the bedroom corners is paper but an adhesive backed paper....skimmed over.....there is no plaster or material between the tape and plasterboard, no wonder it's failed so badly......!!!

Bottom line- am I wasting my time with the patching plaster?? I think it's more suited to the job at hand than the jointing compound which looks more suited to new boards and tapes....I'm filling channels so am in effect patching??

Respect to you guys that do this day in day out.....a real skill to this (that I don't have lol!!)

You won't be able to sand down the plaster as well as the jointing compound its not good for jointing , I've never seen an adhesive backed paper tape for jointing before and any paper tape should have compound under it or it will blow

The test patch I've done has sanded down really well using a medium grit paper.... I'm going to sand a part with fine paper then paint over it a few coats and see what it looks like in comparison to medium . I was a conservation stonemason for over 20 years and having worked with lime mortars I'm monitoring it as it sets to find the optimum point to sand it without too much effort!!! The adhesive backed tape is a joke....on us!!
I can't see any other way of doing this short of ripping down the ceiling and putting up new boards and starting from scratch, so I may as well persevere.....I'll report back either way and give an update...ta for all the advice so far!
