The self-leveling epoxy polymer concrete was poured from buckets into the bead left from the last placement in windrows, and spread by two crew members using 24" wide gauge rakes. It was then backrolled by two more crew members using 9" and 18" spiked rollers. "Another guy used a hand-trowel for all of the detail work on the edges and around every door, etc.," says Adney. "In all, we applied the overlay at a thickness of 1/8" over 10,000 sq. ft. in two hours and 20 minutes and left it to cure overnight." Rake. He was followed by two team members equipped with 18-inch wide rollers with Purdy 3/8-inch nap covers. Adney describes the coating process, "Once the workman with the squeegee was approximately five feet in front of the backrollers, the crew members with the rollers would backroll the wet epoxy. Then a person wearing spiked shoes would begin to hand-broadcast the alumi- num oxide anti-slip aggregate into the wet epoxy. The men would then encapsulate BELOW The two-component 100% solids epoxy top coat gives the sealed floor a glossy finish that is more reminiscent of a John Deere Factory show room than a farmer's tool shed. The unpro- tected concrete floor has transitioned from a never again nightmare to a coatings dream thanks to proper specifications and application technique. the aggregate with epoxy by back rolling. After three hours, the installation was finished and it took a total of five hours on the project that day." The next day, the fifth day, the heavy equipment was moved back in place. In fact, with the high gloss of the CrownShield system and the farming equipment in place, the "tool shed" looks more like a John Deere Factory show room than a storage and repair facility. "Now the concrete is not only protected, it is 'Green' compliant," says Adney with obvious pride. "And it looks good too. Hopefully, the farmer will 'never again' have to hassle with a nightmare floor." A Bumper Crop Of Lessons Although the BodyTek team didn't have to wait for months to see the results of their hard work, there are some similari- ties between this flooring project and the work of the farmer who commissioned it. Simply put, in concrete as in farming, you reap what you sow. Poor preparation will doom even the most carefully applied coating. Sloppy work will yield sloppy results. Improper chemistry will create off-ratio coatings or off-ratio concrete. But in the case of this concrete floor, the failure was fixed, the lessons were learned, and the floor should last for seasons to come. CP 84 CoatingsPro J January 2009
