Fifth Avenue in New York. Rodeo Drive in Beverly Hills. In every major city there is one street that captures the essence of the city—shops, restaurants, nightlife. For people around the globe, the very mention of those street names conjures up visions of excitement—real or imagined. In Miami Beach, Florida, that street of dreams is the famed Lincoln Road, steps from the beach and home to some of the most exclusive and eclectic shops, art galleries, and restaurants in America.
One of the architectural gems of South Beach’s historic street is to be found at 605 Lincoln Road, a gorgeous example of Art Deco architecture built in 1932. Renovated and converted into mixed-usage in 2005, 605 Lincoln Road features a Starbucks on the ground floor, luxury condos on the middle floors, and SapientNitro, an international technology services firm that houses its data center on the top penthouse level. However, in keeping with South Beach’s historic sense of preservation, the structure is still “known to locals as the former Sony Music Building,” explains Daniel Pena, the manufacturer’s representative/inspector for HydroStop and a South Beach native. “Back in the day, Sony was an iconic presence on the Beach. In fact, the roof still has a covered area where the music company used to showcase concerts.”
From Waves Of Music To Waves Of Rainwater
“The property management company, Lionstone Development, wanted a roofing solution that would maintain a leak-free building, but given the famous nature of the building and the site, there were some restrictions,” Pena continues. “First, because the building is historic, the existing roof could not be torn off. Secondly, they wanted to be able to use the roof as a walkable deck, but with no resemblance to a typical roofing application.” He adds with a chuckle, “Ironically, the building’s cooling tower units are located directly over the data center for SapientNitro. A strong roofing system was a must.”
 The location meant that “there could be zero disruption to the tenants, or to the businesses and pedestrian traffic surrounding the building,” says Pena. Location also was a meteorological factor as wind from the beach precluded any use of spray equipment. At least Miami Beach has good weather, right? “This job was scheduled to be completed during Miami’s rainy season—June and July—we actually ended up with six weeks of application time during a four month period due to the weather.” But it is the result of what happened during those six weeks that actually changed roofs up and down Lincoln Road.
Although the 11,400 sq. ft. (1,059.09m2) lightweight concrete (LWC) roof deck was in fair condition, the owners wanted to keep it that way. As Pena says, they wanted to “ensure that the data center below the towers did not and does not experience water intrusion.” Since the cooling towers emit water as a by-product of the building’s cooling system, in hot and humid Miami Beach, that calls for a robust waterproofing solution. The owners turned to Hydro-Stop’s Premium Coat System.
As Pena explains, “Premium Coat is a fluid-applied, 100% reinforced, water-based acrylic elastomeric roof system that has been FM tested for water leakage, wind uplift, hail damage, flame spread, and resistance to foot traffic.”
But, recognizing the importance of the “Sony Building’s” roof, the South Beach native had a design trick up his sleeve. “I thought it would be cool to do a wave pattern on the roof instead of the traditional plain white,” he recounts. “The waves echo the beach and the Art Deco feel of the building itself. And reinforce the primary initiative of the roof project—having a warranted, water-tight, walkable roof system that doesn’t look like a roof system.”
Not surprisingly, the owners loved it and Pena and a crew of four were soon on the roof getting started.
Protecting The Past With The Future
 The crew first performed an elevation survey to determine the directional flow of water over the LWC deck. Based on the survey results, and in order to combat ponding, they installed tapered ISO board to promote positive drainage.
Next, using industrial brooms, the crew removed all of the debris from the roof. This was followed by a power wash of “plain water run through a 3,000psi pressure washer to remove any excess roofing granules, gum, cigarette butts, and other assorted debris,” explains Pena.
Then it was time to apply the coatings. First, in preparation for the System installation, a slurry of Barrier Guard was applied to the LWC as a primer using stiff bristle brushes at a rate of 150 sq. ft./gal. (3.57m2/L). With the primer in place, the Premium Coat System could be installed.
The crew used brushes to apply one coat of Foundation Coat at a rate of 25-40 sq. ft./gal. (0.594-0.951m2/L) onto the roof. While this was still wet, they applied the Premium Coat Fabric, “overlapping adjacent runs of the fabric a minimum of 4" (10.16cm). This was immediately topped by another coat of Foundation Coat,” Pena says. “This was all done in one wet-on-wet application step. Then, when that had dried, we applied two coats of Finish Coat in two separate applications using 1 ¼" (3.18cm) nap rollers. The combined total rate of coverage for the Finish Coat applications was 70 sq. ft./gal. (1.66m2/L).”
When that had cured, it was time to “catch a wave” and install the non-skid Traffic Coat in the wave pattern.
“Actually creating the wave pattern was easy. There was an outline already engraved into the concrete. It was like a blank coloring book. We just followed the engraving and didn’t have to use a grid or stencils.” Pena describes the process: “We used rollers to apply the Traffic Coat in a wave pattern in two separate applications—the standard ‘Cotton’ color and ‘Patina Green’. Each coat was applied at a combined total minimum rate of 65 sq. ft./gal (1.54m2/L).” Suddenly there were waves on top of the roof.
And did they ever make a splash! “The former Sony Building roof was our first truly decorative roofing system on South Beach,” Pena says proudly. But it hasn’t been the last. Businesses up and down Lincoln Road and the surrounding strip have taken notice. (Editor’s Note: Read about one of these projects in the January 2012 issue of CoatingsPro.) Pena continues, “South Beach is in the midst of a major preservation boom and the roof at 605 Lincoln Road is on the cutting-edge.” Now it seems that Miami Beach’s famed Lincoln Road is home to world-class shopping, dining—and coatings projects.
