when skimming walls, can you do it over backing paper or does it have to be directly on the plasterboard??

Answer:

I'm no expert but would think you would need to remove backing paper before plaster goes over it , or paper will become very wet and start peeling away with plaster attached ........................... :)

Apply oil based Kilz first. It seals off the paper so that the moisture cannot penetrate.
