What are the guidelines painting a brand new house? Is it true painting 2 coats too fast makes holes in the paint allowing moisture in?
Any experienced painters out there? I really need a source or link for this too so I can back it up. Thanks and any guidelines on painting a new house MUCH appreciated!
(I know there's only a M$1 tip but it's all I have :S )

Those little holes actually come from just not being thorough enough when painting, in other words, trying to get the painting job done too fast; not running the brush over the same area enough times, especially on textured walls. They can also occur when a painter is trying to make what paint he has left stretch too far.

M$Here is one example from Behr, exterior water-based primer:
"Dries to touch in 1 hour at 77°F (25°C) and 50% humidity. Lightly stained surfaces: topcoat in 4 hours, heavy stained surfaces: topcoat in 12-16 hours. Longer dry time required in cooler temperatures and in higher humidity."
The paint manufacturer puts specific instructions, as well as safety info, coverage, usage, etc. on paint containers for end users.
Some painting companies will mix their own, or re-use other containers that may not have this same information.

And what about the thing about small holes? Is that rubbish?
Where did _you_ hear it? I showed you my link, you show me yours. ;)
Pinholes can from from painting too fast with rollers. Or rolling over (backrolling) or topcoating wet surface, where your roller will pick. the primer or first coat is not fully bonded to the surface, and the roller action will "pick" or pull up, exposing the material underneath.
I've seen it happen with interior latex that had separated...basically the top half of the paint container was watery paint. The thin coat didn't cover properly.
Be sure to check your math, too. If they started at one side of the house at 8am...finished at noon. Then broke for lunch and started up again at 1pm...they've given 5 hours of drying time to the first side of the house.
That's exactly what I'm looking for!! :S I would've included a link if I had one, unfortunately this was word of mouth from another painter. And I can do the maths :P This guy really did leave only 2 hours between a coat, and it isn't exactly the Mediterranean here. Do you have a link I can use in my defence?
I was told the same thing you were, though. Basically, use the best paint you can afford, make sure it's completely dry before doing the second coat. Also, make sure you're using the right primer. This website goes into some detail, maybe it'll help next time.
