I've recently removed the lining paper in my living room due to damp patches forming caused by the adjacent building.
I've sorted the source of the damp but I have found that there are some large areas of damaged plaster.
The plaster is very old horse hair plaster and I intend to chip off the damaged plaster back to the lath and then re patch the damaged areas.
My question is....what should I fill the damaged areas with?
ShouldI I use a plaster repair formula e.g. Pollyfilla plaster repair or should I just go right in and should I use a multi finish plaster mix.
I'm not overly confident with plaster so any advice would be more than welcome.
