Primer question - exterior

I have a few questions, rather than starting different threads, I'm putting them all here. I

I have to install a new service door on our garage in the next few days, I'm trimming the exterior with cedar, it is the only thing I could find locally that matches other trim on the house.

Will a quart be enough to prime 4" x 1" cedar trim all 6 sides, the door jambs and door (32"x80" door)? I'm thinking the cedar probably will get 2 coats, one side is rough which will be exposed.

Also, I have to get our exterior painted soon, have colors selected and submitted to HOA for approval then I'll find a contractor. I'm hoping it will all be done in the month. Will primer be ok in a month or two or will I need to give it a light sand and another coat?

Live near Phoenix AZ.

Thanks for the help.

 

A quart is more than enough for the 1st coat although I'm not certain about the 2nd coat .... but one good coat of primer is sufficient. The primer should be fine without a top coat for a couple of months.

Thanks for the reply - I was hoping the primer would be good without having to much else than cleaning it before it gets painted.
