She is insistant that we proceed even though I have always heard that treated lumber needs to "age". Any special precautions I can use with this. Im thinking prime it with oil based primer...but I need a little input, thanks.
So, Pro, I should prime it with a high quality acrylic primer, but then what to top coat with? If not enamel, and not water borne, what?And think twice about top coating it with a heavily-enameled product, like a semi-gloss, or those new water-borne trim paints. Too thick and vapor barrier-like to make me feel good about this application.

Can I change my vote to the stain also?
GPI said:Not to get anyones girdle in an uproar, but not all treated lumber is pressure treated, and not all are treated in the same way or same products, so yes it does make a diff. what its treated with and how it was treated to know if it can be primed and painted now or later. As my orig. post states. Seems as if the focus was lost somewhere between I have done it and have heard it cant be done. Again, research your product and you will know. Damn chemists.....lol

Ratrub said:Guys, I use a high grade latex primer (Benjamin Moore or Gripper) but the copper will bleed through (blue). If using a bright white for top-coat, you will more than likely need two coats of a premium latex to make sure you cover the copper bleed. That is my experience for the last year. I've had different reps tell me to use an oil-based primer but I like to use latex whenever I can on exteriors unless I'm blocking stains or sealing alligatoring.
I like solid stains but I have not used any on newly installed pressure treated wood. I would bet that the copper bleed will occur. If I'm using stains on deck boards with traffic, I'll prime the boards with an oil-based primer 1st then use the solid stain on top. You won't get peeling. Sounds funny but i got it from Ben Moore direct and it has worked great for three years. Either way, I think the old belief of waiting until the new wood has aged is wrong. Once the wood has aged, some damage to the wood has already occured. My opinion.
Why not check the moisture with a meter?
How does one go about finding out what and how it was treated with?research your product and you will know. Damn chemists.....lol
