I built a shed and am about to paint it and need to get some advice.
The shed is built with hardiplank siding and wood trim, what I need to
know is what is the difference between the $12.00 a gallon latex paint
and the $30.00 paint. And is it worth spending the extra money and go
with the more expensive just for a shed?

Next thing I would like to know is what should I paint the treated
plywood floor with to give it a protective caoting?

I will be using a Wagner Power Painter-Pro airless painter if that
makes any difference with your advice.

i can't remember what consumer reports said but the best buy they had
was moderately priced, i cannot imagine the $18 difference being worth
it. proper prep and priming is the key.

i suggest not painting the treated plywood floor, i am not sure it will
hold the paint that well anyway, and it's treated so no protection is
needed.

You didn't say how big the shed is. Assuming, say, 10x12 and 6' high, you need
to cover 264 square feet.

That means two gallons of the twelve-dollar paint, and one gallon of the
thirty-dollar paint. So the cheap paint only saves you six bucks, at the cost
of your time to apply an extra coat. And you'll probably have to re-coat it
again a lot sooner than you would have if you'd bought the better paint.

Your best shot is to wait for the expensive paint to go on sale...

Nothing. It's already treated. It doesn't need protection.

Well, you won't have to add water to the cheap paint to thin it for
spraying...
