"I bought this product to paint some steps going into the garage. Most of it was new wood, but some was the old previously painted wood. I primed everything with Zinsser and let it dry overnight. I then applied one coat and was very surprised at how it covered the white primer. The color I used was Stamped Concrete (#7655). I would say that it was about 90% perfect coverage with just one coat. I can't say how well it will hold up since it's only been a week since it was applied, but from the perspective of coverage, I was very impressed."
