Tidying up an upstairs room, I've found to my surprise that what I thought was a concrete lintel with a couple of courses of bricks above is in fact a series of wooden beams one above the other.
It's sound enough, but the problem is the plaster, which came off when I removed a curtain rail (4 inch masonry nails, since you ask).
The original plaster coat was obviously put on by someone who was good. It was solid and very thin indeed.
So now how to replace it? Base and skim ( maximum of a few millimetres only)? One coat plaster?
Above all, how to make it stick to the timber?
