I just recently put a bid on the house that had a colored stucco. The type of stucco that has color already pre-mixed in it. It was done about 10 years ago. Since the stucco already had color it was never painted before. I told the customer, that the house would be primed prior to painting. After i talked with a sales rep at Dunn Edwards store he told me priming is not necessary. I am pretty sure he is wrong, but for a moment he made me doubt. Colored or non colored, if it was never painted, it needs primer first. Right?
