I've recently begun a plastering course at college and although it's early days I've already been given a rendering task. The wall is about 6 feet high and 8 ft long, and is built of concrete blocks.
I know that to prepare the wall I should rake out the joints but I'm unsure whether it should be prepared with PVA.
I'd like to know what the best mix is recomended.
I've seen in other subjects 3:1:1 for the scratch coat and 5:1:1 for the top coat, is this ok?
I would very much appreciate it if anyone can advise me.
