Hi,
We've recently had our ceilings replastered. We were told that we should do a thin coat of watered down emulsion prior to adding coats of normal emulsion on top. But we are not getting the best results as some places look patchy even after a third coat of Matt emulsion.
Some people say you can you use a primer on plaster but as we've already painted on it I just wondered whether we could still do this?
Any advice greatly appreciated.
Thanks
