Thinking about painting your home? Here’s what to know about VOCs, low- and zero-VOC paint, and how to make a more environmentally conscious choice — plus a San Antonio painter offering zero-VOC options.
A fresh coat of paint is one of the easiest ways to completely change the feel of a room.
But if you've started paying more attention to the ingredients in your food, cleaning products, candles, skincare and everything else that comes through the front door, eventually you might find yourself staring at a gallon of paint and wondering:
Wait...what's in this?
Welcome to crunchy homeownership. 😂
The good news is that you don't have to stop painting your walls or start making your own paint out of clay in the backyard. There are increasingly accessible lower-VOC and zero-VOC paint options that can make your next painting project a little more intentional.
Here's what you need to know.
VOC stands for volatile organic compound.
VOCs are chemicals that can evaporate into the air from certain solids and liquids. They're found in all kinds of household products and building materials, including paints, varnishes, cleaning products, adhesives and furnishings.
When you paint a room and immediately recognize that unmistakable fresh paint smell, some of what you're smelling may be compounds being released into the air.
According to the U.S. Environmental Protection Agency, concentrations of many VOCs can be higher indoors than outdoors, and paints and paint supplies are among the potential sources.
That doesn't mean every VOC has the same toxicity or that smelling paint automatically means you're being exposed to something dangerous. VOCs are a broad category of compounds, and their potential effects vary considerably.
But if you're trying to be more thoughtful about indoor air quality, paint is a reasonable place to start.
Walk into the paint aisle today and you'll probably see terms like:
Low VOC. Zero VOC. No VOC. Eco-friendly. Green.
They sound straightforward, but there's a little more to the story.
Low-VOC paints are formulated to contain lower amounts of regulated volatile organic compounds than traditional higher-VOC formulations.
They're widely available now and can be a practical middle ground for homeowners who want to reduce VOCs without dramatically changing how they approach a painting project.
Zero-VOC paints go a step further by meeting applicable limits for products marketed as having zero VOCs.
For indoor projects, choosing a quality zero- or low-VOC paint can help reduce the amount of VOC pollution introduced into the home during painting.
But here's an important Crunch List distinction:
Zero VOC does not necessarily mean zero chemicals or completely non-toxic.
The EPA notes that some products labeled low- or no-VOC can still contain other volatile chemicals, and simply comparing the total amount of VOCs doesn't tell you everything about a product's overall toxicity.
In other words, don't let one green-sounding label do all the thinking for you.
Instead of looking for one magic phrase on the can, think about the paint as a whole.
Here are a few things worth considering:
If reducing emissions inside your home is a priority, look for paints specifically formulated as low- or zero-VOC.
And don't be afraid to ask questions.
If you're hiring a painter, you can specifically request a zero-VOC option rather than assuming that's what will be used.
Certifications can give you another layer of information beyond the marketing on the front of the can.
Depending on the product, you may see certifications or standards related to low-emitting paints and indoor air quality.
This can be particularly helpful if you're trying to compare two products making similar claims.
Here's an environmental consideration that doesn't get talked about enough:
Paint that lasts longer doesn't have to be repainted as often.
Choosing the absolute "greenest" product isn't particularly helpful if it doesn't perform appropriately for the space.
Bathrooms, kitchens, children's rooms and high-traffic areas all have different needs. Durability, washability and the surface being painted should be part of the decision too.
More isn't always better.
Accurately estimating how much paint your project requires can reduce leftover product and unnecessary waste.
If you do have paint left over, check local guidelines for proper reuse, recycling or disposal rather than automatically tossing it in the trash.
Even when you're using a lower-VOC product, good ventilation is a smart painting practice.
Open windows when weather permits, use fans appropriately and follow the manufacturer's directions for ventilation, application and drying time.
Low-VOC doesn't mean you need to throw common sense out the window.
Actually, we'd prefer you open the window. 😉
The paint itself isn't the only thing involved in a painting project.
Primers, caulks, adhesives, cleaners and other products used during prep can also affect what is introduced into your home.
If you're trying to make a lower-tox choice, ask about the whole painting process, not just the final coat.
And there's one especially important consideration for older San Antonio-area homes.
If your home was built before 1978, disturbing old painted surfaces can create a risk of exposure to lead-based paint. The EPA recommends treating paint in pre-1978 homes as though it contains lead unless testing shows otherwise.
That's one area where you definitely don't want to DIY first and Google later.
One of the reasons we created The Crunch List is to make it easier to find local businesses that give San Antonio families more choices.
That includes home services.
Dye Renovations provides interior painting services in the San Antonio area and gives homeowners the option to request environmentally friendly zero-VOC paint for their project.
That matters because sometimes making a more intentional choice isn't about completely changing the project.
It's simply knowing you have an option.
If you're already planning to repaint the living room, bedroom or another area of your home, asking your painter about lower-VOC alternatives is one small way to approach the project differently.
And we love seeing local service businesses make those choices available.
You don't need to become a paint chemist before hiring someone.
A few good questions can go a long way:
A good contractor should be comfortable talking through the options with you.
If you've been around The Crunch List for a while, you know we're big fans of realistic swaps.
You don't need a perfectly "non-toxic" house.
You don't need to rip out everything you own.
And you definitely don't need to panic because you painted your bedroom five years ago without researching VOCs first.
The goal is simply to know more when it's time to choose again.
Maybe this year it's switching your cleaning spray.
Maybe it's finding a local farmer.
Maybe it's replacing a candle.
And maybe, the next time the walls need painting, it's asking:
"Do you have a zero-VOC option?"
That's the kind of crunchy we can actually stick with.
Dye Renovations provides professional interior painting services in San Antonio and surrounding communities, with environmentally friendly zero-VOC paint available upon request.
