Plasterboard on external corner?

[rammylare1]

Hi all,

Looking for some advice regarding plasterboarding.

A small job of repainting a kitchen breast wall has turned into somewhat of a disaster! Removing the old crap proved difficult (paint, followed by wallpaper, followed by more paint, one more coat of wallpaper and then another coat of paint). After eventually removing it all, some of the plasteboard which covered the old closed up fireplace was damaged. I figured id replace the plasterboard but as I started removing it the old plaster starting coming away also.

So basically a repaint job has turned into the breast wall being completely stripped back to brick!

I figured the two options are plastering or plasterboard. I thought plasterboard might look ok (its not a huge wall by any means). However, the plaster also came off from the small bit of wall between the breast wall and back wall (this pic shows it a bit better than im explaining it - https://ibb.co/HVDhyPZ)

I think I can manage the plasterboard of the main wall, but im not too confident on that external corner. Can anybody advise how I'd go about doing that corner without it looking terrible?

Thanks

On the exterior corner, you'd need a metal anglebead. If you aren't confident with skimming the boards fully with multifinish, then a decent finish can be obtained with perseverance, joint compound and a lot of sanding! Have a watch of this

would make more sense if you posted a pic of your own chimney breast?

if you use plasterboard you will need skim beads not angle beads - plasterboard might give you far more difficulties than you would imagine.
depending on why the original surface failed (eg. damp) it might be best to use render.
use plastic angle beads if damp has been an issue.

fwiw: the front of the c/b is the face and the sides of the c/b are the cheeks.

Thanks for the replies guys, I was out when i made the original post so didnt have a pic of my kitchen wall but here it is:

The plasterboarding is sounding like it could be more hassle than I thought. I've never really done it before so wouldn't be too confident in making it look great. I may well get a plasterer in to just get that wall done, I expect it wouldn't be much?

One other quick question - now im back to brick, some of the mortar is loose and crumbling, is it worth me to remove any of the loose mortar and then re-point it prior to getting the wall plastered or plasterboarded?

Thanks again

As Bob says it is worth checking for damp. On a chimney breast it can be as simple as rain coming down the flue, or damaged pointing on the stack. Any signs of damp elsewhere in the room? What is behind the chimney, another room or exterior? Was that air vent covered over before you stripped everything back?

A plasterer should be able to assess what is needed, but a render and finish coat will give the best finish. In terms of prep, the loose material will need removing or stabilising first.

Thanks for the reply. There doesn't seem to be any evidence of damp in the kitchen anywhere. On the other side of the wall is my neighbours kitchen. as for the air vent that was not covered before, the plasterboard was cut to size to keep the vent there and open.

I'm just waiting on a plasterer to get back to me with a price but hes saying that he would recommend plasterboarding followed by a skim.

Plasterer quoted £260 for plasterboarding and skimming the breast wall and left hand cheek wall, that includes all materials. That sound reasonable?

That’d be about right round here, wouldn’t say it’s extortionate
