Plasterboarding over Artex ceiling - Edges ?

[ricky101]

Hi,

Am looking to plasterboard over an existng but very sound artexed plasterboard ceiling; a 900mm wide right angled hall way, and have found most of the answers to the usual diyers questions from other posts.
Thankfully the existing battens are ideally spaced for both angles.

The walls are painted paper which we want to keep, and we also intend to paper over the new plasterboard rather than skimming ( will seal the new plasterboard before papering)

However one little area eludes me, its where the cut square edges of the new board meet the walls. What is the best way to fill that gap , just plaster or something like jointing compound or flexible acrylic sealer etc ?

thanks

Use a filler that goes solid after an hour or so.
Here's what I would do. Mix up a small amount of the filler, not too wet..Get a 1" paint brush and "lightly dampen" the gap as you go, and using a scraper, push the filler into the gap. Continue doing this all around the ceiling line, keeping the wallpaper clean. Once you have "neatly" filled the gap, let the filler set solid, then put some fibre mesh tape along the ceiling line, just butted up against the wall. Go all around the ceiling line with the tape, then go over the tape with a coat of readymix finish compound, to cover it over. That tape will stop the filler from breaking away from the gap. Once the tape is covered and dried out, sand it down with a fine sandpaper, seal it, then you're ready to paper. Everyone has their own way, this is mine and it works no problem.
