Whether you are a DIY or a painting contractor it great information to know what SW paint covers the best. 70- 85% of the cost for a painting contractor is in their labor costs. If a painting contractor is using paint that covers well it can reduce the number of coats and therefore the cost of the job.
To be fair, many painting contractors including myself did not really know which paints covered the best. We had our guesses, and our go-to paints, but did we really go as far as to have a blind study on various background colors? I’ll answer the easy ones for you. No.
I have to admit I’ve always believed that the more expensive the paint the better it would probably cover. My experience told me that Duration covered better than SuperPaint and ProMar 200. And this proved to be true.
However, there were two SW brands that are less expensive than Duration and cover substantially better!
