What are the dark bits? If they're a stain like water, you'll need to use a stain proofing undercoat like Zinsser BIN.Guys, I've put 3 coats of emulsion (sandtex) on the part of a ceiling running alongside an electrical cable conduit. There's still some darker bits showing through. I'm hoping another coat or two will get it completely white. Should I have put some undercoat on and can I still do that now before another coat of emulsion?
