Home Depot sells a Behr Premium Plus Ultra paint that in a single can combines a primer with the finish coat. (May be other brands out there, too.) While the concept is certainly attractive, can we expect it to work as well as separate coats? The literature touts nanotechnology in the formulation. What about proven durability? (Since nanotechnology is so new, I wonder what kind of accelerated tests the paint underwent to simulate real world conditions.) Anyone have first-hand experience with this product or other similar ones?
I'm planning to paint the outside of my home. Most of the shingles are asbestos, the others are wood shingles. Fascia boards are a mix of real wood and pressed paper! (Thanks, Levitt and Sons.) The soffits are a mix of pressed paper and exterior and interior plywood. The house was built in 1967 and everything has been painted many times, except for the soffits and fascias that I replaced last week (with real wood).
For the curious: Those pressed paper fascia boards and soffits are dimensionally identical to standard wood sizes. If all the previous homeowners had kept them well painted for the past 40 years, they would have stood up to the elements remarkably well.
Thanks for your comments.
