I'm working on extending an old cottage with a new section that will be a 60-square-meter angle and have built up a 2m high basement section with Lecablocks. I've seen houses with plaster that looks like it’s sprayed on in a thick layer! How do you do that? Can you do it yourself by renting equipment? The problem I have is that I would like the old wall, which was built in the early 1900s, to look somewhat similar to the new part and rebuilding/plastering the old part to make it look new is not possible, so I thought this sprayed plaster method might be an option! But how do you do it??
