Balancing Air Quality with Durability
About 90% of the VOCs released by alkyd paints enter the air during the first 10 hours after painting. But health-threatening “aldehyde” emissions can continue for more than 120 hours—even after odors have dissipated.
Latex paints contain less VOC content than alkyd paints, but VOCs from latex paint may continue to offgass for up to 3.5 years when painted over gypsum board.
A paint that is “low VOC” may still be releasing HAPs, or hazardous air pollutants. It’s important to know what replaced those VOCs in the mix.
Blistering of paint on wood siding sometimes originates from inside the home—when water vapor from moist areas such as bathrooms is allowed to saturate the wood.
