What Is VOC in Paint? Why It Matters for Your Health and the Environment
Over a year ago, I wrote a comprehensive piece on paint types. I touched on VOC in paint (volatile organic compounds), and recommended using low or no voc paints. Then I dusted off my hands, feeling informed and safe.
But then came a question.
I was recently asked, “Why can’t we get the popular gel stains dominating social media feeds in Europe?”
I had no idea why!
Those rich finishes are everywhere online, yet gel stains are unavailable in European stores. Not on Amazon, or even in the UK, which often has products mainland Europe doesn’t (Hello, General Finishes!).
Curious, I started digging. What I found wasn’t just an answer—it was an eye-opener.
It made me realise just how dangerous VOCs are and why they deserve far more attention when we choose our products.
As furniture refinishers and DIY enthusiasts, you play a crucial role in protecting yourselves, your families, clients, and their loved ones by understanding refinishing products and choosing them wisely.
In this article, I’ll share what I’ve learned about VOCs, the health risks, European regulations, and how you can use this knowledge to create safer, more sustainable pieces for your customers.
So, let’s embark on this learning journey together.
What Are VOCs?
Volatile organic compounds are chemicals that evaporate into the air at room temperature. They’re added to paints, stains, and finishes for practical reasons—making products easier to apply, dry faster, and last longer.
The problem?
These compounds don’t just disappear when they dry. They continue to be released into the air, sometimes for weeks, months, or even years.
I have yet to find it listed on any product just how long the VOCs remain active for that specific product.
VOCs in Paints and Stains
In refinishing, VOCs are most commonly found in:
- Solvents: Help dissolve pigments and improve consistency.
- Binders: Aid in adhesion and durability.
- Additives: Enhance flow, leveling, and surface performance.
These chemicals might be essential to the formula, but their emissions can be harmful.
Health Risks of VOCs
When I first started looking into VOCs, I was shocked by how little I knew about their health effects.
Short-Term Exposure
If you’ve ever felt lightheaded or experienced a headache while painting, that’s likely due to VOCs. Other common symptoms include:
- Eye, nose, and throat irritation.
- Dizziness and nausea.
- Allergic reactions or rashes.
Long-Term Exposure
But things can get far more serious. Prolonged exposure to high levels of VOCs can lead to:
- Chronic respiratory issues, including asthma.
- Liver and kidney damage.
- Central nervous system damage.
- Increased risk of cancer, especially with certain compounds like formaldehyde and benzene.
Remember, it’s not just you as a refinisher who’s at risk—lingering VOC emissions from a piece you sell can affect your customers, their families, and pets. Their safety is as important as yours.
Environmental Impact of VOCs
Health risks aside, VOCs are a major contributor to air pollution. In sunlight, they react with nitrogen oxides to form ground-level ozone, known as smog. This doesn’t just harm the environment—it exacerbates respiratory illnesses and contributes to climate change.
Understanding the environmental impact of VOCs is crucial in our efforts to create a healthier and more sustainable world.
Reducing VOC emissions in refinishing is a good place to start if we want to leave a positive mark on the planet.
My Rabbit Hole into European Regulations
When I first started refinishing, I was dazzled by-products from big-name American brands. I still am sometimes!
The results of gel stains are undeniable: a perfect finish.
So why couldn’t I find it anywhere in Europe?
As I began learning about VOCs, I realised that many of those products I couldn’t find, including gel stains, are simply not compliant with the EU’s stricter health and safety standards.
Is Europe Setting the Gold Standard or Being Overly Cautious?
Europe is taking a step in the right direction.
Knowing what we now know about lead in paint, it’s hard to believe now that the United States only banned lead-based paint in 1978.
However, several European countries had taken action decades earlier. France led the charge in 1909, with European countries quickly following suit.
This difference in regulatory timelines reflects a broader cultural approach: Europe prioritises precautionary measures regarding environmental and health risks.
Key EU Regulations
Here are the regulations you need to know if you’re refinishing or selling to clients within Europe:
Directive 2004/42/EC (Paints Directive):
Focus: Limits the VOC content in decorative paints, varnishes, and refinishing products.
Impact: Products are classified by type (e.g., interior wall paints and wood stains), with strict VOC limits for each category.
This regulation ensures that products sold in the EU are safer for consumers and the environment. However, it also means we need to choose our materials carefully, and some North American products will simply not be available.
VOC Limits in the EU
Understanding the specific VOC limits the EU sets is crucial for compliance and safety. Here’s a breakdown:
Interior Paints:
- Water-based paints: Maximum VOC content of 30 grams per litre (g/l).
- Solvent-based paints: Also limited to 30 g/l.
Exterior Paints:
- Water-based paints: Maximum VOC content of 40 g/l.
- Solvent-based paints: Can have up to 300 g/l.
Varnishes and Stains:
Interior and exterior trim varnishes and wood stains:
- Water-based: Maximum VOC content of 130 g/l.
- Solvent-based: Maximum VOC content of 400 g/l.
These limits are significantly stricter than those in other regions, including North America. Therefore, verifying products’ VOC content is essential to ensure compliance when purchasing them from outside the EU.
VOC-Compliant Paint and Stain Brands
The glitz and glam of social media can make it feel like we simply do not have the right products in Europe to refinish successfully. But in reality, that is simply not the case.
There are so many European Brands that meet European Regulations and provide excellent products. Let’s explore a few of them in detail.
Here are a few European Brands that you need to explore:
Rubio Monocoat
What I love: A plant-based, VOC-free finish that protects wood in just one coat.
Best for: Floors, tables, and other high-traffic pieces.
Fusion Mineral Paint
What I love: Gorgeous zero-VOC colours with a built-in topcoat.
Best for: Furniture makeovers with a contemporary feel.
Borma Wachs
What I love: Traditional craftsmanship meets eco-conscious innovation.
Best for: Classic wood finishes that align with EU standards.
General Finishes
What I love: Water-based, low-VOC finishes that don’t compromise performance.
Best for Cabinetry and furniture projects.
Osmo
What I Love: Natural oil-and-wax-based finishes with low-VOC content, enhancing wood’s natural beauty while providing long-lasting protection.
Best For: Interior wood surfaces like floors, furniture, and cabinetry.
Practical Tips for VOC-Free Refinishing
Using VOC-compliant products is just the start. Here’s how you can refine your process:
- Ventilation is key: Always work in a well-ventilated area or outdoors when possible. Use your Respirator if your product has VOCs.
- Read the labels: Look for certifications like the EU Ecolabel or French A+ VOC emissions labels.
- Store properly: Tightly seal cans away from heat to prevent accidental emissions.
- Choose water-based products: Water-based paints and finishes often have significantly lower VOC content than solvent-based ones.
Why Should this Matter to You?
When I started refinishing furniture, I focused on the finish product and did not really think about a piece’s safety or long-term environmental impact. But learning about VOCs made me realise something bigger: every piece I work on is a chance to make a statement, not just about aesthetics but about safety, sustainability, and care.
This is especially critical for those of us selling refinished furniture. Our customers trust us to create beautiful, durable pieces for their homes. When we choose low-VOC or VOC-free products, we offer more than just a safe, eco-conscious product—we give peace of mind.
And here’s the hard truth: many products marketed as “premium” or “innovative,” especially from North America, don’t meet EU standards. As European refinishers, we must stay informed, read labels carefully, and prioritise compliance over convenience.
My Final Takeaway
This journey into VOCs has been eye-opening. It’s made me rethink the materials I use, the impact of my work, and the legacy I want to leave in this industry.
By embracing the EU’s strict standards, I’ve realised I’m not just protecting myself or my customers but contributing to a healthier, more sustainable future.
So, take a moment before you pick up your next brush or roller. Look at the label. Think about the piece you’re creating and the space it will inhabit.
A little extra effort now can make a world of difference later—for you, your customers, and the planet.
Let’s choose to create responsibly, one beautiful piece at a time.

Gosh, what an eye opener. So I’ve used only low voc until I used the osmo grey beige wax and then their clear oil. Both say high voc…. and in their data sheet it’s aliphatic hydrocarbons. (She says lol). It says 30-60% on the sheet but doesn’t give reference to that. So…. now I’m wondering what I can use instead?
Hi Emma, I know we discussed this in DM, but I wanted to come back to it for others with the same questions. If you are looking for a low or no voc product to provide a grey wash look to wood, Rubio Monocoat oils are low voc. Or you can consider using a paint wash to get a similar effect and then top coat with something like polyvine wax like finish. I know we were both surprised to see hardwax oils listed at 500 g/l voc.
