A Guide to Low and Zero-VOC Paint
A fresh coat of paint has the power to completely transform a room and how we feel while in it. We might choose a soothing pastel to welcome a new baby or freshen a drab nook with a bold hue to inspire creativity. Studies show that the color of one's environment can influence the body. Purple, for example, affects the body's circadian rhythm and can help reduce feelings of stress.
But there is more to paint than just color. Each manufacturer uses a slightly different paint formula, including volatile organic compounds, also known as VOCs. These paints may look great on the wall, but silently off-gas dangerous chemicals that could harm you and your family.
Low and zero-VOC paint contains fewer if any VOCs and is a much safer choice for your family and the environment.

How Long Does Low-VOC Paint Off Gas?
The duration and intensity of paint-related off-gassing are primarily dependent on the type of paint used, how long it takes to cure, and how many coats are applied. Most latex paints, for example, off-gas for roughly three to five years, but can continue up to 10 years.
Off-gassing is strongest during and immediately after painting a surface. If you've ever painted before, you're probably familiar with the smell of paint. That smell is a good indicator that paint containing VOCs is currently off-gassing. Still, it will continue to release toxins into the air long after the scent dissipates.
While there is no way to eliminate off-gassing except by using 100% zero-VOC paint, it is possible to speed up the process.
How Can You Speed Up Off-Gassing?
It's always best to allow interior paint to dry entirely before inhabiting the space. However, for many of us, that just isn't possible. If staying with friends, family, or at a hotel is out of the question, there are ways to help paint dry and off-gas quicker.
Can You Trust Low-VOC Labels?
When buying anything, it's essential to read paint labels and manufacturer information to ensure you're buying true low or zero-VOC paint. There is still not much regulation on the types of VOCs that can be used in paint. Some low-VOC paints may still contain harmful toxins like ammonia or acetone. Extended exposure to ammonia can cause eye and skin irritation and has even been shown to cause and exacerbate lung damage.
Is it Safe to Paint When You Are Pregnant?
Expectant mothers should take extra precautions during painting projects. The best way to protect an unborn baby is to hire a professional painter and for the mother to steer clear of newly painted areas. If you absolutely must paint the nursery a new color or refinish baby furniture while nesting, it's essential to take extra precautions. Even zero-VOC paint in a pastel color can contain up to 5 grams of VOCs per liter.
Choosing Low or No-VOC Paint
As our understanding of VOCs grows, more and more low and zero-VOC paints are entering the market. Below are just a few low and no-VOC paints currently available. Remember to check the paint can label for third-party certifications and ingredient lists before you purchase it.
