Filling small areas in lime plaster


New Member
Is there any reason why I can't use lime-based undercoat plaster to fill holes about 1" wide and 15mm deep in 100 year old lime plaster? I have approx. 50 holes where rawl plugs have been removed to sort.

Am thinking it might turn into a lot of effort building the depth up in such a small area. I guess most people would turn to filler rather than using plaster, but do lime-based fillers exist?
