Repainting the Tallest Towers in Peru

The Problem

Located on the outskirts of Lima in the Andean mountain range, the tallest towers in Peru are 176 meters tall and were beginning to show signs of corrosion. Plus, the towers needed fresh coatings to comply with Peruvian air signaling regulations because of color loss due to extreme UV exposure. To specify an effective coatings solution, several factors had to be taken into consideration, including product quality, resistance to sunlight (UV), method of application, ease of maintenance, and the impact of the coatings on painters themselves.

The Situation

To solve the issues above, Induron specified Armorlux H-1212 as a primary layer to protect the aged galvanized steel from corrosion and Indurasil Silicone Alkyd as the top coat in alternating colors of Signal Orange and White. These colors are resistant to degradation by the effects of sunlight and environmental pollution. Plus, the glossy finish prevents contaminants from easily adhering to the surface of the structure. Because of the proximity of these very tall towers to the Pacific Ocean, large deposits of soluble salts and chlorides needed to be removed prior to application of the primer and between the primer and the application of the finish coat. Nemetsa was the pre-approved contractor chosen for this high profile job and provided a qualified team of 25 to prepare and properly paint this giant structure.

The Results

The Induron products proved to be successful, and the client was satisfied with the work and daily coordination. The team also managed to overcome the issue of environmental care.
