“If you can’t preserve the palm of your hand on the exterior wall of your house for extra than a several seconds, it’s way too very hot to paint,” de Paz suggests.

How CR Checks Exterior Paint
To determine a paint’s durability, we apply two coats to pine boards. Then we mount the boards on angled racks on the roof of our headquarters in Yonkers, N.Y., to see how properly the paint withstands the factors. Then? We wait.
Since the boards are angled (not vertical as they would be on a household), they are far more uncovered to light-weight and the elements. Each and every yr of screening is equal to about three several years on vertical surfaces. A few years later, our benefits give you an plan of how the paint will glimpse immediately after nine many years. We also check for mildew resistance by inserting painted panels on vertical racks in a shady space of our campus.
Choices in our exterior paint ratings that market for considerably less than $25 for every gallon involve finishes from Coloration Spot, Glidden, and Valspar. Paints in the $25 to $48 variety involve all those from Behr, Clark+Kensington, Glidden, HGTV Residence, and Valspar. And you can shell out $68 or a lot more for a gallon of Benjamin Moore or Sherwin-Williams paint.
CR associates can keep studying for ratings and evaluations of the exterior paints that scored 72 or greater (out of 100) in Consumer Reports’ tests. All are self-priming, but be confident to test the can for scenarios when priming is advisable.
