Hi,
I've removed the skirting board and a radiator in my lounge.
Behind the skirting is just bare brick and behind the radiator was plaster but the whole lot fell off so there is now bare brick here too. The walls are to be skimmed in a few weeks time but I'd like to cover the brickwork up now. The depth to bring in line with the existing plaster is about 10-15mm.
Would it be OK to fasten plasterboard to the brickwork? The reason I'd like to do this is that when the new skirting board is fitted it should have a nice, flat surface to attach to so would be easier to install and would be a better finish. I'm concerned though that when it is skimmed the plaster will react differently to the original plaster and the plasterboard and that this may cause cracking.
Also, has anyone any ideas on the reason for the plaster blowing behing the radiator? I'd expect it's just because of the age and the heat it's had from the radiator but if anyone knows of anything else which may have caused it I'd be eager to know.
Thanks, Matt
