Paint That Cleans Itself
This exterior acrylic paint promotes water-beading to let dirt roll off without having to manually wash surfaces.
Sherwin-Williams has introduced an exterior acrylic paint designed to shed dirt on contact with water. Emerald Rain Refresh is self-priming and comes with a limited lifetime warranty against blistering and peeling. Rick Watson, the company’s director of product information and technical services, said he could not discuss the proprietary formulation in detail, but that it includes a “precision-engineered, cross-linking polymer chain that promotes water-beading at the surface.” Dirt should wash away in the rain or with a garden hose, and because the additive is integral to the paint, it won’t wear off or become less effective over time, Watson says.
Rain Refresh grew out of another self-cleaning Sherwin-Williams product called Loxon, an acrylic for masonry surfaces that wasintroduced three or four years ago. Customers said they liked it, but wished it could be used on other surfaces. So, Watson says, Sherwin-Williams applied the same technology to an acrylic paint that could be used on a variety of substrates, including wood and vinyl.
The paint can be applied in temperatures as low as 35°F and contains less than 50 grams of VOCs per liter. It is CARB and LEED v4 compliant, according to specs listed at the company’s website. It’s available in 1-gal. and 5-gal. containers and in three sheens—flat, satin, and gloss. It costs around $75 for 1 gal.
