Best wood to use to construct a home and best paint for it's external surface are two important things to consider.
They sell all kinds of paint at Lowe's and The Home Depot and other retailers around. - but what is the best paint for exterior wood on a house, in particular, the roofing edge: fascia board?
Wood framed houses are USUALLY made from the wood of the Yellow Pine tree. The most common 2X4, 1X4, 2X6, & 1X12 etc. are of no.2 Yellow Pine. There is also a no.1 Yellow Pine, but that is more expensive. There is also White Pine.
So they usually go with the cheaper end of Pine wood to build a house frame. The idea is, Pine is soft wood and easy to screw and nail into it and put in brackets and make rafters, frames, window frames, walls and so on.
But does anyone ever think about the paint?
You usually paint the wood around the exterior of the house with basic EXTERIOR LATEX PAINT, but ...
There are so many latex paints that is is often over looked that they come in different grades. Premium, Yea. I got that. Premium is said to be the higher end of paint as to it's quality but don't get me to lying. I don't really know if that is the absolute truth as far as exterior paints are concerned.
You know the fact of the matter is, simply put, paint that goes on the surface of bare wood has to have time to dry and set before a second coat goes on it. And for that matter, if only the external surface of the wood is painted, what about the other parts of the board? The edges and the back side of it? That makes me think. Maybe wood that is treated against rot and warping from moisture?
Well, Do you paint a board on all sides, before nailing it to the exterior sides of your house? They put the bare wood on it. They paint it not with a brush but with a paint spray gun, connected to an air compressor.
Then you have to consider, what is the best paint? Well, certainly, the paint that goes on using a paint sprayer, must be thin enough to go through the jet nozzle. So, the paint is thicker if it is to be applied by a roller or a brush or both. I have given it some thought. I figure if you put the paint on thick it will better protect the wood, right? Well, yes and no. The paint that is applied using a jet sprayer from a powered air compressor, might better cover the surface and dry faster allowing for a second coat.
I still do not know what is the best and more sure method of paint application to the surface of wood on the exterior of a house's siding and fascia boards and vertical edge boards, TRIM. In the old days, before the fancy compressors, people would paint using a 3 or 4 inch wide brush and take their time doing it. As to the quality and type of paint for painting wood surfaces, on to bare wood, requires first of all a PRIMER, which in many or most cases, the primer is put into the paint so it goes on as colored paint with primer base. That way you can paint the bare wood using a primer which is basically a way to seal the wood against exposure to moisture and humidity and liquid water and ice. The many different temperatures of the 4 seasons and the intensity of sunlight and wind and rain and ice and snow all tend to be quite destructive to wood and even painted wood surfaces that are exposed to the outside weather 24/7/365.
If you are replacing trim or framed window boards or roof edge fascia and landing boards with fresh new lumber, you will have to consider these effects that the 4 seasons of the year have on wood and paint on the surface of wood.
The primary thing to consider is wood quality first, then ask a professional carpenter what is the best paint and what are the best and longest lasting nails to use. Along with considering the differences between lumber types used in basic house construction, and nails and brackets and the angles of inclination and angles of the cut, there are also many other things to consider but all in all, if you want the wood to last a long time after it has been caulked and painted, you should seriously consider buying the best quality - longest lasting paint with a guarantee as to how many years it will last under normal weather exposure.

I once worked formulating paint at MAB in Philadelphia. But, to be honest, I never cared that much about paint. If I had to say which paints I think would be best, they wouldn't usually be latex at all, but alkyd or oil or epoxy paints. Not what people use. And I am not "in the know" or a skilled painter.

Quality and time are both important points.

I have a spare room (my man cave) which is in the process of being renovated. You sound like you know a thing or two about this kind of thing so could you could you come over next week and complete the project?1
