Hi,
Hope this makes sense.
Just had some plastering done on a 1930’s ish terrace. It seems where there is really big gaps near the floorboards eg behind where the skirting board will go, that bonding has been used then small strips of plasterboard and then more bonding to build it out. I’ve now cut away a bit of this and the plasterboard is damp yet the the brick behind is bone dry. Surely this is not right?
depends how long it has been if its been couple of days then nothing to wory about because you used alit of bonding it takes time to dry and if its been couple of weeks then something is wrong, it could be damp in the wall, and for the gap between wall and the skirting board or skirting board or the floor is either the wall been plastered not even or the floor.
Sounds like a bodged job, you don't put plasterboard between two layers of bonding, it should have been all filled in with just plaster.
Plasterboard is like a sponge as most off modern plastering materials and all gaps between walls and floors should have a gap so the air flow continues and drys the wall if gaps are to big there many alternatives to packing it out first replace size skirting board if available
No there should always be a gap at the bottom for air
No it's not right if your having damp come through the strip are not good you need an undercoat of bonding to pack it out
As a plasterer this is just a cowboy method hoping you wouldn't notice now it's gonna cause a little mess and more board and plaster to repair need a quote contact me I will rectify others mistakes
