I have no choice but to use a pine lattice moulding 1/4" x 1/3/4" for exterior use. I thought that maybe I could find this in treated but no luck. (Unless someone knows they actually make it in treated).

So, my question is, if it's painted right away with a quality exterior primer/paint and protected from moisture that way, will it be ok? 20 years of life and I'd be happy anyway. Should it be sealed before painting? --thanks

Paint will help, certainly, but it's not a miracle coating.

Longevity will primarily be dependent upon the environment it is in. If the lattice is well supported and NEVER touched by anything, then it will last years, however, the first kid, dog, or object that touches it, that lattice will likely be nothing but splinters on the ground.

The lattice around my deck is close to thirty years old. It has only been stained. Other than some staples coming loose, that were easily repaired, it's help up well. I don't think it's treated.
I've seen lattice in two different thicknesses. Sort of a standard and a heavy duty type.

I thought you could get them in Redwood, which will be better than pine.

Use stain, because stain actually penetrate the wood.

In California, redwood is a commonplace material, no so much across the rest of the nation. Pine isn't a terrible exterior material, it still has plenty of the same tanins that keep redwood rot/pest free, I'd choose spruce or cedar over pine, but you can only get what is available.

Yeah, it won't be touched ever because I'm using it up high on the house. Will be painted white -- wonder if using a sanding sealer on it first might be a good idea? -- thanks

No need for a sanding sealer, 1 - it's an exterior feature, 2 - it's being painted with a full bodied pigment paint. Sanding sealer is for closing open pores in wood so as to attain a glassy smooth clear finish, or as a wood prep so that it takes stain more controlled/evenly. It is an unnecessary step for your project, and I'm not even sure if they make an exterior grade sanding sealer, if they don't, then you'd just be making a mess of things trying to use it.
