Just a few blocks from the Country Music Hall of Fame, Nashville’s non-profit “Rocketown” offers young people a drug- and alcohol-free venue that includes a concert hall, indoor skateboard park, and some really old concrete floors.
The facility got pro bono help with the floors March 14-17, as two Craftsman -level accreditation courses taught by the Concrete Polishing Association of America swept through, in conjunction with the Concrete Decor Show.
CPAA instructors Brad Burns, First American Floor Co., Grapevine, Texas; Roy Bowman, and George Gooch, Concrete Visions Inc., Tulsa, Okla.; and Derek Mackenzie, Floor Lab, Toronto, Calif., taught the back-to-back two-day courses. Reps from CPAA member companies supported the training with donated equipment and supplies, including PROSOCO’s Joe Reardon and 25 gallons of Consolideck® LS® (Lithium-Silicate) Hardener/Densifier.
Along with Rocketown’s aged concrete floors, two classes of concrete professionals — mostly flatwork and polishing contractors, Brad said — were the beneficiaries of the training. Along with hours of hands-on training on real-world floors, participants got classroom training in “The Polishing Process,” “The Science of Polished Concrete,” “Estimating Polished Concrete and more.
The Monday-Tuesday class took on the abused and deteriorating 2500 square-foot concrete floor in Rocketown’s first-floor coffee bar.
Pre-polishing repair work to the floor included treatment with Consolideck® LS® (Lithium-Silicate) Hardener-Densifier, following grinding with 80-grit metals. Husqvarna GM300 grout went down to further improve the surface for polishing after grinding with 150-grit metals. The two treatments did the trick, and the formerly soft surface ended with a hard, shiny 1500 resin finish.
The Wednesday-Thursday class faced its own challenge, Brad said. They had to lift some heavy-duty machines — the STI Prepmaster 2417 and the HTC 650HDX — with a Skytrack crane to the 2nd-floor mezzanine overlooking the skateboard area.
The 1,000 square feet of mezzanine concrete was in much better shape than the coffee bar, Brad said. Other than location, and a thin gray surface coating which ground off easily, it presented no obstacles.
Along with the class participants, Brad said, the crew at Rocketown and the Concrete Decor Show were great to work with and helped tremendously.
“Everyone put in long hours and worked extremely hard to advance the education, benefits and aesthetics of polished concrete,” Brad said.
