[how much paint to buy?]

You will need twice as much as the coverage figures on the can claim! :-|

Nonsense.

Not at all - it has been my experience that the coverage figures need
halving (approximately) on nearly every paint I have every applied.

This is not because it is crap and needs 2 coats - this is beacuse I don't
roll it out to atoms thick like the manufacturer assumes.


And that's assuming good paint...

Doubly nonsense. Twice as much with *crap* paint, sure. For good paint,
the label is pretty close, although coverage is usually closer to the low
end of the range.

No - 5 times as much with crap paint, because you'll need to double the
number of coats as well!

Example:

Dulux Paint - a very good UK consumer[1] brand - the coverage abilities are
excellent - 1 coa over a similar colour of existing paint, 2 coats over
anythign else, including new plaster (OK, there is a "mist" coat as well,
but that's a given).

Dulux "Once" - surprisingly it usually does actually cover in one coat with
a change of colour. However, even this, the coverage figures on the can
leave a *lot* to be desired...

[1] which means it's more forgiving of mishandling, but also because it
happens to be easy to buy, being popular
