Key Takeaways: Commercial sports floors like Junckers or Granwood require high-slip resistance (R9/R10), specialized court line marking, and high-traffic lacquers like Bona Traffic HD for long-term durability.
The Problem: Worn-Out, Slippery Sports Surfaces
School halls and community gyms in the UK face immense pressure. Over time, the protective lacquer on timber floors wears away, leaving the wood exposed to moisture and dirt. More importantly, the floor loses its slip resistance, posing a significant health and safety risk to students and athletes. Faded court lines only add to the frustration, making professional sports and physical education difficult to manage.
The Agitation: The Cost of Neglect and VAT Implications
Delaying a commercial floor refinishing project often leads to more expensive repairs down the line. If the wood becomes grey and water-damaged, a simple ‘buff and coat’ is no longer an option, and a full sand-to-bare-wood becomes necessary. For schools and charities, managing budgets—including VAT—is critical. Using non-specialist contractors who don’t understand the ‘moisture content’ of large-scale timber floors can lead to warping and floor failure, wasting precious public funds.
The Solution: High-Performance Commercial Sanding
Our team specializes in Granwood and Junckers restoration. We use heavy-duty machinery like the Frank Spider for a level finish across large areas. Our process includes ‘water popping’ to ensure deep penetration of the seal, followed by the application of Bona Traffic HD—the world’s leading lacquer for high-traffic areas. We precisely mask and paint sports lines using specialized two-pack paints that bond perfectly with the timber, ensuring they last as long as the floor itself.
Pro-Tip: Curing Times in UK Humidity
In the typical UK climate, Bona Traffic HD is dry to the touch in 2-3 hours, but full curing takes 3 days. However, if the humidity is above 60%, we recommend extending the curing time before allowing heavy footfall or replacing gym mats to prevent ‘clouding’ in the finish.
