Which paper layers to remove before applying bonding agent?

[jimpmorrison]

Hi

After steaming the painted lining paper from plaster boarded walls in a bedroom I have been left with two or three layers of what appears to be thin brown paper on top of the boards. I was advised by a plasterer that I should remove this and then apply a bonding agent before they can skim the walls. I am struggling to work out exactly which layers to try to remove. I would really appreciate any advice the forum might have on how far I need to go before applying a bonding like green grit or blue grit to prepare for plaster. Please see the pictures. The image with the largest area of very distressed looking grey patch is where a plasterer attempted to tear at the wall and I think to try and apply PVA to see how it responded.

kind regards

you’ve took the layer of paper off he needs to re board it and that’s if the plasterboard isn’t f**k*d because you took a steamer to it

Wow,
I'd try and get it like pic 3 if you can.

Then apply.

thats actually a plasterer who tore the paper off in the way you can see in picture 3. He said he was testing it

Plaster can crack if you take wallpaper off with a steamer do you get where I’m going with this it’s over plasterboard it’s probably turned to mush if you’re not lucky
Plasterboard has a core and a layer of paper either side of it was lined I understand it’s tricky to get lining paper off this
It looks like paint aswell that’s flaking maybe it was painted before it was lined
Need to overboard it

Or save yourself a few quid and see you in here in a month when bits are falling of or it’s cracked
