painting walls advice/do i need to primer?
Also check and see if the paint company makes the color you want in red base which will make a world of difference in the coverage.
Second of all - if it is a Ralph Lauren Paint color you have - make sure you get the RL Deeptone Primer to go with it.
It tints to a colour that is very close to the top coats.
With this primer you should be able to cover in three coats of finish - so that would be four all together......
Without a primer very close in colour (pink - or white) you could see 5-7 coats and still not get the correct colour or coverage.
Tinting primer is a waste of time and money.
Primer is not needed when changing 'sheen'.
Hope this helps out.
