I have a project in a mountainous area that gets moderate rain & snow during winters, and warm, dry summers. We are about to install exterior siding- a combination of concrete lapsiding (Certainteed- primed), Shakertown shingle panels, and some T1-11. The paint scheme has not been decided on at this time, and it could be months before it happens- the lap siding is factory-primed, the shingle panels will remain natural wood but will need some kind of sealing, and the T1-11 will be primed before it is installed. I am wondering how long the siding (esp. the T1-11) can remain unpainted, and still expect the primer to function properly, and not have to prep & re-prime & paint. Suggestions on primer products would be helpful, too.

What primer are you using. I know SW says it needs to be topcoated within 2 weeks. Usually 30 days is tops for good adhesion
I would use a long oil primer. I usually use SW or Ben Moore
I haven't decided what primer
I haven't decided what primer to use- I'm open to some suggestions. I used Kilz on some T1-11 on another project many months ago, knowing painting immediately wasn't an option, and now I'm sure it needs to be prepped/reprimed. I primed it just get the wood protected somehow.
I don't do a lot of painting (as you can tell), so the advice of those who do a lot is appreciated.
At Shakertown we recommend, as does the Western Red Cedar Lumber Association, that cedar siding be finished as soon as possible after application. Prefinishing on all sides is a preferred method. Please refer to this link for complete recommendations. http://www.wrcla.org/installation_and_finishing/finishing_siding/default.htm
