"The house is 20 years old, sided in clear cedar clapboards, and was previously painted with solid oil-based stain from Benjamin Moore. The contractor scraped all loose paint, and there was some bare wood. He then sprayed and back-brushed the body with Emerald flat. Even after three coats on one side fo the house the areas that were scraped bare weren't covered. In addition, the trim areas that had overspray from the body needed two coats to cover. Emerald satin finish was used on the trim, mixed to match BM Navajo White.
I went back to the SW store, and they gave me a gallon of Duration to see if it covers the bare spots showing through on the siding. The contractor is going to paint the bad sections on Tuesday, if it doesn't rain. I'll post results. My contractor has always used Duration, and feels it is vastly superior to the Emerald. He noted that the Emerald is much thinner than Duration, as well as not covering well.
On a positive note, the in-store team at the Salem, NH store was very professional and helpful."
