Welcome to the second in our series of posts on no-VOC paints. Today we are reviewing Harmony, by Sherwin Williams.
Manufacturer: Sherwin Williams
Paint: Harmony Interior Latex Flat Paint (color – Extra White)
Cost: $36.99 per gallon retail
Composition: Water based acrylic latex. Contains titanium dioxide, nepheline syenite, vinyl polymer, calcium carbonate, kaolin, mica. Formulated with no silica.
VOCs: Less than 2g/l (grams per liter)
Color range: Most colors are available. Sherwin Williams’ “Blend-A-Color” tinting can add to VOC level.
Coverage: Estimated by mnf. at 350 – 400 sf per gallon
Paint odor in can – Smells like the tempera paint we used as kids. Odor undetectable more than 12″ from freshly opened can.
Consistency of paint – Smooth, slightly thin, light splatter
Coverage – 2 coats just covered existing dark tan paint
Drying time – 45 minutes till dry to touch. Waited recommended 4 hours before applying second coat.
Odor after one day – Very faint, almost undetectable
Adhesion after one day – Applied clear tape to paint. Some residue showed on tape, but did not affect surface of painted wall. Tape was hard to remove at first.
Note: Paint provided by Sherwin Williams for our use in test.
Conclusion: This paint is definitely low odor, and has the added benefit of being anti-microbial. Other than the vinyl polymer, the paint basically consists of water and ground minerals and rocks (see composition above). Because it is slightly thin in consistency, I imagine this would do very well in a sprayer, which coupled with it’s relatively low price point, might make it ideal for larger projects and painting contractors, as well as those looking for an affordable option in no-VOC paint. However, I would advise using primer before trying to cover a darker color of paint.
Editors note: After several days drying time, there was a noticeable difference in color between the Sherwin Williams Harmony and the other paint products tested. When viewed from an angle, the original paint color for the wall could be seen through the white Sherwin Williams paint. This is probably due to the thin coverage noticed earlier. This paint might work well for new wall surfaces, or walls that have had good primer applied, but it does not seem to work on previously painted walls.
I really like the fact that Sherwin Williams took the time to redesign their can as well as their paint. The can is 100% post consumer recycled resin (plastic), with a label made of 75% recovered fiber and 25% post consumer waste, printed with soy ink.

Note: We chose not to apply paint under ideal conditions, including the use of a primer, so your results may vary. To read more about how we approached our review process, please read this post.
