Hi all,
I'm going to remove a chimney stck in my first floor in the next few weeks. It's already gone in loft so no structural probs, and I have written conf that I don't need building regs approval.
Looking in the loft, there is no cavity behind the chimney, so there will be a 2inch recess when I take down the stack. So I guess batten out and Plasterboard, and skim to match the existing plaster.
Questions:
1) should I be using some kind of insulating plasterboard since there is no cavity at that point?
2) the existing plaster is lime (I've pulled out horse hair when making good an old screw hole). Am I right in thinking I can't expect gypsum to marry up to it without cracking? Can I put lime on plasterboard in the new bit, or do I have to make laths or something similar instead of PB?
3) assuming I have to use lime, is a week likely to be long enough for it to cure ready for painting?
No doubt these questions will seem insignificant when I tear the room apart and find I need to insert a new joist or something...
Many thanks,
Andy
