Hi All,
I am revamping my lost conversion and I am after some advice! I am new to the forum and do my own DIY.
Bought the property 3 year ago and the loft conversion was done by previous owners in 1993. There is stair access and a dormer and the structure seems very sound.
The plaster has some cracks where the plasterboards meet and this is pretty much throughout the loft space.there are up to 10mm gaps in the corners of the room and plaster has simply given way meaning it looks shocking and I’m going to reboard the lot.
Ive started stripping the plaster board off (back to joists and rafters) and here’s where I’m not sure what’s going on:
Plasterboard is 9mm thick
Looks like a pre coat of grey plaster on top of the plasterboard between 6-10mm thick!
Then some pink skim about 2mm thick
Why is there such a thick pre coat and why is this needed? I thought you could plaster with pink skim straight on top of plasterboard? There’s no chance of plastering on top of this as the existing skim is way too thick, unreliable and I’d rather have piece of mind knowing done a decent job with fresh boarding and skim.
To top it off the previous owners did not white wash the plaster so the paints is brittle and comes off in big shards.
Out of curiosity I’d like to know what the thick grey plaster is and why it was needed? And if I’m replacing the boards, is there a particular board I should buy?
For added info, there is a velux window either side of the room, there are vents in the roof and there is enough space between the rafters and the Battons for airflow the circulate.
Any advice would be mich appreciated!
Cheers
Matt
