Plastering question

davidjhope · March 05, 2013, 04:41:03 PM

Hi,
I'm starting a project sealing up a room that is currently open plan. I need to know how thick the plaster finish will be on the plasterboard so it matches with the other walls. I was thinking about 4-5mm is this too much?
Thanks in advance
David

Hi David

I'm not a plasterer but have had a few rooms done in my house and as I understand it the plaster is usually about 3mm thick. If there are any plasterers out there though I'm quite happy to be proved wrong!

Good luck with the project.

Thanks for the quick reply.
I've tried the online DIY forums before and found them a bit agressive to DIY'ers so my hope is that one of the friendly members here will help.

From what I've seen it's just thick enough to cover the plasterboard. I would guess 2mm ought to do it.

The "skim"coat would be around 2mm thick on both render or plasterboard. If you're house is less than 15 or so years old, make sure it is not dry lined and "jointed" ie filled and taped between the sheets edges. regards rodders

Getting plastered has never been a problem!

Getting plaster to STAY on a wall, I employ an expert!

My brother in law is a drylinner/plaster and he tells me its about 3mm thick.

Generally speaking,if you intend on buildin a partition wall using either wooden or metal studs,this being the frame which the plasterboard is attached to,a plastere will just put a thin skim coat on to make the wall look just like the other walls and to cover up the plasterboard joins and where the new partition wall joins the existing ones.

As for membranes and suchlike,unless the house is of a timberframe construction,these are not required due ro it being an internal wall.So dampness problems won't exist as long as the pre-existing timberframe construction has not been compromised.

In my work history,I contracted for a company as a plumbing and heating engineer on some timberframe properties it had built so don't have quite the knowledge of a housebuilder.
