Choosing the right finish for your hardwood gym floor can be confusing. There are many different types of recoating finishes on the market that are designed to keep your sports floor looking good and in tip-top shape. But for the most part, you’ll want to choose between the basics—either an oil-based poly or a water-based sports floor finish. Below, we’ll explore the difference between these two types of recoating substances and which one might be the best choice for your gym. First, let’s uncover recent changes in the sports floor industry and what that could mean for your facility.
Recent Changes in the Industry: VOCs vs. Tradition
Many sports facilities take a traditional approach to gym floor finishes and recoating. The conventional way of recoating a gym floor will give it a golden-yellow glow and hue. In contrast, the newer style of doing it can make gym floors appear white and almost sterile. Achieving either aesthetic often comes down to what finishing coat is applied to the sports floor.
The Traditional, Golden Look for Sports Floors
Getting a sports floor to take on a yellow appearance requires the application of treating the bare, sanded wood with an oil-based poly sealer—usually applied in two coats. Then, graphics and game lines are drawn once the coats dry and cure. Finally, two more coats of oil-based poly are applied over the top of the game lines and paint for the finishing touch.
That’s the classic way of doing things when it comes to gym floor coatings and finishes. Oil-based polyurethane coatings are solvent-based. For the last 30 or so years, this has been the go-to method for refinishing a gym floor.
Water-Based Recoating for Gym Floors: A Low VOC Method
Many DIY gym floor recoating jobs make use of oil-based finishes that have high levels of VOCs. However, professional gym floor installers and gym floor coating manufacturers now have a more extensive range of formulations for recoating gym floors at their disposal. These newer lines of finishes are often water-based, yet still, give sports facility owners more options for the final aesthetic.
But when it comes to using oil-based finishes, a professional gym floor installer is best equipped to apply these materials safely, more so than a DIY enthusiast.
Why would someone want to use an oil-based poly for recoating a gym floor?
An oil-based poly offers gym owners many unique benefits, aside from aesthetics.
- Durability — An oil-based finish is sturdier than its water-based cousin.
- Adheres to the industry standard — Oil-based polyurethane finishes for gym floors are the industry standard. The look and quality they offer have been used for decades as the go-to for sports floor finishes. While water-based finishes are gaining market share, they aren’t as recognizable.
- Rich color — Unlike a water-based finish, oil-based poly will give the floor a deep rich amber hue. Maple, the wood used for sports floors, is white with brown undertones. Applying an oil-based finish to the wood will highlight the grain while adding depth to the undertone.
What are the benefits of using a water-based finish for gym floors?
Other than possessing a low amount of VOCs, water-based recoating has its own set of unique advantages.
- Shorter dry-time — Oil-based finishing coats typically require at least 24 hours of dry time between coats. And the final cure? That can take up to a month in some cases. Otherwise, the finish might mar. If your facility sees a lot of heavy use, and extended downtime for the gym would devastate your business, you may want to consider using a water-based finish. Between coats, water-based finishes only need about three hours of dry-time. For the final finish, your gym can be ready for use again within a week. A water-based finish only requires about six to seven days of curing time to be fully dry and free of becoming marred from foot traffic.
- Transparency — Water-based coatings go on clear and stay transparent. Since a water-based finish will allow the natural grain and color of the maple to shine through, this may be ideal for gyms that require the application of colorful graphics, logos, and many painted lines. Amber tints that occur when oil-based poly is applied may clash with specific logo colors. In some cases, a water-based finish may help your facility appear more professional and polished.
- Eco-friendliness — Eco-friendliness is becoming more and more important to consumers and gym owners. Water-based coatings are far more gentle on the environment than their oil-based counterparts. Manufacturers are responding in kind to these consumer sentiments with water-based coatings that are recyclable and long-lasting. A product with a longer shelf life reduces waste.
Oil-Based vs. Water-Based Recoatings for Gyms: A Takeaway Message
Today’s sports facility owners are fortunate in that they have far more options when it comes to picking the right recoating material for their gym. You do not have to sacrifice durability for environmental sensibilities with water-based recoatings. But a water-based recoating won’t give the floor a warm tone, and it may require you to have the floor serviced more frequently.
