I just spent the last two days steaming off wallpaper in the ground floor bedroom of my 1890s London Victorian house. Under the layers of wallpaper I found this grey plaster-like or cement like material.
Google is telling me it doesn't look like lime plaster... In some places it has crumbled and cracked though the crumbly bits may have been a layer addition by a previous owner.
Can anyone tell me:
(1) what it is,
(2) whether it needs undercoating (or papering) before painting with Dulux Diamond/Endurance Matte,
(3) if so what with, and finally
(4) what I can fill cracks and holes with before painting starts?
I'm a relative decorating newby, though have repainted many a painted interior wall. But I can't afford to spend a lot getting a pro to decorate this room. I also have a friend moving into it in a week so need to fix very urgently. So any DIY advice hugely appreciated.
Thanks,

Ps. As a bonus round question, I uncovered pink foam under a layer of heavy duty lining paper on the outside wall and on the ceiling. The pink foam is somehow reinforced with plastic or vinyl threads a bit like fishing wire. The last person to strip the wallpaper had gouged it in many places and I managed to tear a few holes myself. Prize offered for (A) identifying the material (B) suggestions on whether to pull it off the wall or paper over before painting again with the Dulux trade matte.
