Plastering repairs - Advice needed

[TrimTheKing]

Evening all

I have a problem that I need the help of this wise forum to fix. We have some porthole windows in the house and it seems that the daughter of the previous owners liked to sit at her desk with feet up on the edge of the sill/cill while chatting girly talk to her mates.

The plaster now looks like this...

SWMBO is desperate to get the hideous dayglo pink paint covered over with a nice muted shade in time for guests coming next Monday, so I need to get it fixed by then.

My thought was as follows:
- Cut away the damaged plasterboard/plaster
- Screw a batten across the front (wall part rather than inside the curvy bit)
- Patch the inside of the curved sill/cill up to the batten (following the curve with my float)
- Remove batten once plaster gone off and then make up the front/wall part
- Sandy sand and Robert's my Mother's brother.

Is that the best way to go about it or should I be doing something easier/better?

Thanks in advance...

Make the batten deeper say some ply and shape to required curve then it becomes a plastering edge to work off just like a plasterers bead for straight work.

Good plan OLD, will do. Thanks for that.

Do you think just finishing plaster will be enough to deal with it or will it need some packing out if I have to remove any broken plasterboard?

You might want to try and re-form the circle with something like these B&Q Arch Formers

You could look for an Arch kit that could fit as well (I've used these before) that's the correct radius of your window - you'll just need some tin snips to cut down the grill to something more appropriate.

The nice thing with this sort of thing is it gives you a solid metal rim / edge to work from. The only down side is you would need to chip away plaster to accommodate the grill which you will need to plaster over. I've used heavy duty staples (think Black and Decker staple gun ) to hold these things in place to the underlying woodwork (or plasterboard). Its only a temporary fixing as when the plaster dries out it should be quite solid.

Should give you a nice neat edge to work from too.

Cheers

Thanks Wayne.

To be honest I did wonder why it hadn't been done with these in the first place as similar windows in our old house were. Will see what I can find.
