Help identifying Paint/Wallpaper

Camster

That doesn't look like the lath & plaster that I've recently removed in my house. My walls had a much smoother finish.

I believe they stopped using lath & plaster around the 1930's -40's so if the house was built after that, it probably won't have it.

That plaster is not in amazing condition in my view so you're going to need to line the wall with lining paper and wallpaper over that I would say.

I had walls in a bedroom which were in a similar state - pitted but solid and used a nice anaglypta over lining paper and then painted the anaglypta a lovely colour. I didn't want the grief and hassle of replacing the plaster work and the end result was a good one (for a bedroom).

On an extension we had done I had the freshly plastered wall lined with lining paper and then painted that because the finish was perfectly smooth.
