case study:
Montreal Olympic Park is a source of national pride, with the Olympic Stadium, a 541-foot observation tower (165 meters), and the Biodome. Built for the 1976 Summer Olympics, the stadium is now used for sporting events, concerts, and other activities. Each year, hundreds of thousands of visitors enter the park.
ArmorThane Montreal has worked on various coating projects throughout the Olympic Park for several years, including the Biodome. The latest project involved coating the stadium’s gutter system to repair it and prevent further concrete deterioration. The domed roof shape and harsh weather have damaged the large gutter troughs that channel the run-off from years of rain erosion and the impact of ice and snow.
Besides the deterioration, the challenge in repairing these fairly narrow eave troughs was the height. A scissor lift was used to raise people and tools to the 53-foot-high sections. With ArmorThane’s mobile coatings unit, all of the power and high-pressure spraying equipment could remain in the trailer below.
GETTING STARTED
Sitting high above the ground, harnessed workers first scraped off old finish to ensure the ArmorThane coating formed a permanent bond to the concrete. Once cleaned, sheets of plastic were secured to the outside of the building to prevent overspray given the wind velocity at those heights.
ArmorThane Highline 310 polyurea coating was sprayed onto the surface to form a waterproof barrier that expands and contracts with weather changes. It doesn’t crack, peel or corrode with rain run-off or snow build up. Coatings hold up in temperatures from -80°F to +280°F.
FINISHING TOUCHES
The final step is to roll on a UV stable coating to match the white exterior.
The ArmorThane coatings will protect this part of the building for years. It’s a great one-time investment.
The applicator ended the project by conducting tests on the polyurea applied substrate. This involved affixing 20mm dollies to the surface. After allowing the glue to set for 24 hours, the dollies were then drilled using a 20mm coring hole bit.
- Pull 1: 619psi (95% substrate, 5% cohesive failure in coating)
- Pull 2: 714psi (100% substrate failure)
- Pull 3: 488psi (100% substrate failure)
- Pull 4: 621psi (40% substrate, 60% adhesive failure between substrate and coating)
- Pull 5: 251psi (75% substrate, 25% adhesive failure between substrate and coating)
- Pull 6: 723psi (100% substrate failure)
The ArmorThane coatings will protect this part of the building for years. It’s a great one-time investment.
