Wall/plasterboard gaps

[walls]

I have installed some gyproc triline but have ended up with some gaps of around 1.5cm in places around the edges of the wall where the walls are not straight. What's the best way to fill these? I have some gyproc acrylic sealant but will this fill large gaps like this? I also have some wickes ready mixed plaster, will this do the job?

Many thanks.

Put scrim tape across it and skim it

cheers for the reply, I'll have a go at that.

Sorry but 1.5cm is too wide a gap to just scrim & skim even on conventional Wallboard. You should have fitted the boards as tight as possible to maintain the integrity of the TriLine in doing its job but since you have what you’ve got, pack put the gap with Bonding plaster as deep as you can (skip the Wickes readymix) & then skim.

The gap is filled with the skim while skimming and the mesh stops it cracking

Fine for small gaps of a few mm but with a gap of 15mm, I would pre-fill, tape & skim; just forcing Multi in there is not a good idea.

I'd fill it out gap first prior to fitting tapes you'll find the tape will sometimes disappear in to joint if gap is too big, ideally try filling out with plaster or jointing compound then sand it down then apply self adhesive scrim tape prior to plastering. This will avoid the potential of an uneven surface if you do it all in one go.

No need to sand it, as long as it's filled flush & taped the skim will sort it out. I would always use Bonding but I’ve nearly always got some handy; buy a small bag of one coat plaster if you prefer but I wouldn’t advise using filler or jointing compound. Give the strip a couple of coats of 1:4 PVA/water mix or it’ll suck the life out of the strip of plaster over it well before you’ve finished.

the gap is only where the board butts with a bit of the wall which is uneven. Not about to buy another expensive board to fill a 15mm gap! Can you use bonding to fill the whole gap 52mm deep?

Cheers for the advice.

pack out the gap with Bonding plaster as deep as you can....
