Quick question for a plasterer

[LaserTam]

Walls need skimming, they did have lining paper on them with several layers of paint. Lining paper has been removed, but there is some residual wallpaper glue in places which is proving stubborn. If it was just being painted it without skimming, it would need to come off (to give you an idea of how much there is), but if skimming over the top, does it need to be removed or can it remain?

Cheers

Thanks, I think.

Just to reiterate, lining paper has been removed, there is just some residual glue in places, which is stubborn and would take some effort to remove. Rather not have to waste the effort.

Maybe I will just PVA it...
