Recently the client mentioned that a few people have painted a coat of paint over his plaster but myself and him are unsure whether they have mist coated it / watered it down. Or if they have just painted a full thick coat straight onto new plaster. What should I do in this situation? Should I send it all down/scrape it all off and start again. Or should I paint over it with a watered down coat and see how it holds up ?
Is there a problem with the existing emulsion peeling off? If not carry on with a full coat of fresh emulsion.
