Oil-based wood stains have been a popular choice for professionals, and for good reason. They penetrate deep into the wood, hold up against the elements, and deliver long-term durability you can count on. When performance matters, oil has always led the woodcare industry.
The most common assumption is that oil-based stains are associated with higher emissions, higher VOCs, resulting in pollutants released into the air. EXPERT’s low VOC wood stain is here to show you why that is no longer the case.
EXPERT™ Professional Wood Care has introduced the first exterior oil-based wood stain to achieve GREENWISE® certification for low emissions. This isn’t just progress, but completely changes the game for woodcare performance.
What Is GREENWISE Certification?
GREENWISE certification is an independent standard used in the coatings industry to identify products that meet defined low-emission requirements.
To qualify for this certification, a product must meet the VOC limits established for its specific category:
EXPERT Clear and Transparent Finishes comply with the ≤100 g/L VOC requirement.
EXPERT Semi-Transparent and Semi-Solid Finishes meet the ≤250 g/L VOC requirement.
In other words, it’s a measurable way to evaluate how a product is formulated, without the guesswork.

What are VOCs?
VOC stands for volatile organic compounds, a standard measurement used in the coatings industry to evaluate emissions.
What This Means for Oil-Based Wood Stains
Traditionally, oil-based stains have been associated with higher VOC levels. That’s been part of the trade-off for their performance. That’s where the EXPERT™ Professional Wood Care formulation comes in, to change the perspective of oil-based stains. Independent testing shows that EXPERT Stain & Seal Fence & Deck formulation delivers VOC levels of ≤100 g/L, meeting GREENWISE certification standards.
Why does this matter? Because it shows that we can provide you a quality, professional-grade product that delivers and meets low-emission standards.
