GREENGUARD Gold Certified Wood Finish

GREENGUARD Gold certified label for Rubio Monocoat Oil Plus 2C

Oil Plus 2C is GREENGUARD Gold certified, the highest level of UL's GREENGUARD indoor air quality program. It is a 0% VOC hardwax oil for interior wood floors, furniture, cabinetry and millwork, and its GREENGUARD Gold certification means it meets the indoor air standards used for schools and healthcare facilities.

What does GREENGUARD Gold certified mean?

Products that have achieved GREENGUARD Certification are independently tested by UL to meet some of the world's most rigorous third-party chemical emissions standards. Products are tested in emissions chambers to measure the volatile organic compounds (VOCs) and other chemicals they release into indoor air.

GREENGUARD Gold is the stricter of the two levels. It sets lower total VOC limits and adds criteria for sensitive people such as children and the elderly, which is why it is the level referenced for schools and healthcare facilities. For a wood finish, that means the test measures the finished surface's effect on indoor air, not just what is in the can.

GREENGUARD vs GREENGUARD Gold

Both are UL emissions certifications. Standard GREENGUARD covers general indoor use. GREENGUARD Gold uses stricter limits and includes health-based criteria for sensitive populations. Oil Plus 2C holds the Gold level.

Is GREENGUARD Gold certified worth it?

"Non-toxic," "natural" and "low-VOC" are not regulated terms, so any brand can use them. GREENGUARD Gold is a measured, third-party result you can check. If you are finishing a nursery, a child's room, a classroom or anywhere people spend a lot of time, it is the clearest way to compare wood finishes on indoor air quality.

A 0% VOC wood finish certified for indoor air quality

  • 0% VOC. The emissions testing behind GREENGUARD Gold confirms Oil Plus 2C's VOC-free formula.
  • GREENGUARD Gold certified at UL's strictest level of indoor air quality testing.
  • One coat. Color and protection in a single layer, so less product goes into the space.
  • Interior use. Oil Plus 2C is made for interior wood only.

GREENGUARD Gold certified flooring finish

Most GREENGUARD Gold flooring lists cover vinyl, laminate and prefinished products. For solid or engineered hardwood finished on site, the finish determines the floor's indoor air performance after install. Oil Plus 2C lets flooring contractors and homeowners specify a GREENGUARD Gold certified finish for new floors and refinishing projects.

FloorScore vs GREENGUARD Gold: FloorScore is an indoor air quality certification for flooring products. GREENGUARD Gold applies across product categories and uses stricter limits for sensitive populations. Oil Plus 2C carries GREENGUARD Gold.

Oil Plus 2C also holds other indoor air certifications used in Europe, including Eurofins Indoor Air Comfort Gold, the French A+ label, M1 and EMICODE EC1 PLUS, and it is Red List Free.

For schools and healthcare facilities

GREENGUARD Gold is the certification level referenced for schools and healthcare facilities, where children, patients and staff spend long hours indoors. Oil Plus 2C meets that standard, so architects, designers and contractors can specify it for classrooms, libraries, clinics, hospitals and offices with wood floors, paneling, furniture and millwork.

Because Oil Plus 2C colors and protects in one coat, there is less product and less time on site, which helps on projects that need to reopen quickly.

For furniture makers and nursery projects

Parents looking for GREENGUARD Gold certified cribs, dressers and bed frames care about the finish as much as the wood. Furniture makers and woodworkers can use Oil Plus 2C to offer a GREENGUARD Gold certified finish on solid wood pieces and share the certificate with their customers.

Oil Plus 2C also complies with EN 71-3, the European toy safety standard for migration of hazardous elements, so it suits wooden toys and children's furniture. Finishing a cutting board or butcher block? It is food contact compliant under EC 1935/2004 and FDA 21 CFR 175.300. See our food contact compliance page.

About the GREENGUARD Gold formula

In early 2023, Oil Plus 2C moved to its current GREENGUARD Gold certified formula. The updated formula has lower viscosity, so it spreads more easily and goes further, and it stores better at high temperatures. Pre-2023 and current batches can be mixed on the same project. The color Pure looks different in the can than it did before 2023, but there is no difference once applied.
