What is Gym Floor Refinishing?

Gym floors endure heavy use over time, resulting in wear, scratches, and reduced traction. Refinishing is crucial to restore slip resistance, protect the wood from further damage, and maintain a polished appearance your school can be proud of. This process not only extends the floor’s lifespan but also reduces long-term costs by preventing the need for a full replacement.

Kimminau Floors’ gym floor refinishing service transforms your gym floor back to its original condition. Our process includes sanding the surface down to bare wood, making necessary repairs, applying fresh logos and game lines, and sealing it with durable finish coats. This comprehensive approach revitalizes the floor’s appearance while ensuring it remains safe, resilient, and ready for high-performance use.

How long does the refinishing process take?

The gym floor refinishing process typically takes 7-10 days, depending on the size of the gym, the condition of the floor, and the complexity of customizations like game lines or logos. Here’s a general breakdown:

  1. Sanding and Repairs (2-3 days): Removing the old finish, repairing any damage, and preparing the wood surface.
  2. Game Lines and Custom Artwork (2–3 days): Painting court lines, logos, and other design elements.
  3. Sealing and Finishing (1–2 days): Applying multiple coats of sealant and finish, with drying time between each layer.

Frequently Asked Questions (FAQs)

Gym floors should typically be refinished every 8–10 years, depending on the level of use and wear. However, regular maintenance and recoating every 1–2 years can significantly extend the time between full refinishing projects.

Factors that affect how often your gym floor should be refinished include:

  • Usage Levels: High-traffic facilities, such as schools and community centers, may require more frequent refinishing.
  • Floor Condition: If you notice deep scratches, discoloration, or loss of traction, refinishing may be necessary sooner.
  • Maintenance: Proper cleaning and regular re-coating can reduce the need for refinishing by protecting the floor’s surface.

While there may be a small amount of dust generated during the sanding phase, Kimminau Floors uses dustless refinishing equipment equipped with HEPA-filtered vacuums to capture nearly all of the dust at the source. This minimizes the mess and disruption to your space.

Additionally, our team takes extra precautions to keep your gym clean, ensuring that any remaining dust is quickly vacuumed up during the process. The goal is to provide a clean, efficient refinishing service with minimal disturbance to your facility.

Kimminau Floors uses high-quality, durable finishes specifically designed for gym floors. We offer both oil-modified urethane and water-based urethane finishes, each with their own advantages:

  • Oil-Modified Urethane: Known for its deep amber tone that enhances the natural beauty of the wood and provides a durable, long-lasting finish.  This finish will have a stronger odor and take longer to dry and cure.
  • Water-Based Urethane: A clear, low-odor finish that dries faster and has a more eco-friendly profile. It provides excellent durability and performance while maintaining the natural look of the wood. May require multiple coats to achieve the same build as OMU.

Yes the court lines and logos will need to be repainted during the refinishing process.  This would be a great time to implement any changes that are desired with graphics or new game lines.

Yes, Kimminau Floors offers a warranty on our gym floor refinishing services. Our warranty covers the quality of our workmanship and the durability of the finishes we apply.
