Top 10 Best Exterior Primers of 2019 – Reviews

An exterior primer is as important as any of the top coats which go on after it. That’s because the best exterior primer not only provides a stable foundation for the layers of paint which are applied after it’s been applied to the surface but also prepares the painted surface in numerous ways. And that’s why many of them are formulated with a variety of different stain blockers or mildewcide additives. Finding the best exterior primer, however, isn’t always an easy proposition. Sometimes it takes time and research to find the best one for your intended application. Fortunately, I’ve found ten of the brands that I feel are the best and listed them below for your convenience.
