replace or clean the drywall

[Yrrol]

have a boiler room, sooty, with special drywall on the walls and ceiling. I'm now going to remove the boiler etc. and make a laundry room...

The question is, how do I remove all the soot in the easiest way, just painting over it seems a bit unprofessional.

Or should I replace the drywall with some other type perhaps?

Screw on an additional layer of plasterboard on the outside! Double plasterboard is never wrong in a boiler room.

Well, I'm not really keen on making my future laundry room even smaller... But there are pretty thin repair boards as I recall, so maybe it wouldn't be the end of the world.

But then there's also the smell issue, all the soot might be deep in the boards and could haunt one?

You are at least sure that it's plaster and not eternit? Anyway, I would probably remove it to be sure about the smell.

Had a painter here and he encouraged me to change, he liked the current scent though but explained how simple it was to replace the boards, so that's probably what I'll do... I hope they don't cost too much anyway.

How big is it and how many sheets are we talking about? Are the seams filled or are the screws visible?

If the seams aren't filled, it's easy to take it down and put up new ones, and it doesn't cost much either. When you say you don't want to do partial work, I assume it's not that big, so the cost is likely modest.

Buuuut. If you then spend the time washing the whole thing, which doesn't take too long considering the surface area, a couple of rounds of filler and a roller isn't a bad idea either.

What are the conditions?
