I am plastering an area of about 2.5m high and 10m long with no breaks. Using multi finish. Going straight over the top of existing plaster ( has been painted, but have keyed it up). I could do it in two halves, but i was wondering if there was anything out there that would delay the existing...
I wonder if anyone can help. I have quite a large wll to finnish plaster on my own. Does anyone out there know how to stop the plaster setting so quicky, is there anything I can add to it? I have heard that Lime Putty works, but not sure what the finish will be like or how long it gives you...
