What's the best approach for painting a light emulsion onto a
previously emulsioned surface which is dark in colour? I have a
feeling that the dark colour will "bleed" through the new emulsion.
Obviously a couple of coats of the lighter colour is one option, but
are there "undercoat" products which can block the original underlying
Started this job today. One coat has left the old colour bleeding
through very heavily. Second coat will most likely improve the
situation. But it certainly looks likely that a third coat will be
required on this situation.
The opacity of the more expensive paints is due to it having more
titanium oxides than cheaper stuff.
Also a tip I heard some time ago is to put a little of the dark colour
in the new paint. I don't know why it works, melding the grins perhaps.
I don't know if has to be the exact shade either but I doubt that.
Sometimes a completely different dark colour will do it. If you wanted
to get rid of a strong red, a grey coat might be the first option for
then white or whatever on the grey.

Hi. Just paint over it, simple as that. The only complications are you
will need 1 or 2 more coats, and if the new paint is _really_ crap
it'll be hard to cover the old colour fully. But its rare you get
paint that bad.

underlying dark blue finally disappeared.
Maybe I could have loaded an earlier coat a bit thicker, however I
didn't feel that was a good idea otherwise I may have got the paint
