The problem isn't too much suction it is not enough suction. I want the opposite of size or PVA.

No, the paste is failing because the water is being sucked out of it.

New plaster has to be sized before wall paper can be pasted to it.

The water leaving is normal drying process, I'm not seeing how that can be the problem.

The paste is sucked out of the paper which then falls off.

Any porous surface needs to be rendered impervious to prevent this.
You can use "size", PVA or keep applying coats of paste (letting dry between) until you get a shiny surface.

An interesting idea, but since I had no trouble papering onto an untreated very absorbent surface last time I doubt it.

It's factual information.

My father was a painter & decorator BTW.
