The repair of the upper parts of Fingers ( mobile access unit to the plane ), is approximately 800 m2 waterproofed by Tecnocoat P-2049 pure polyurea membrane, all surfaces to treat are metals.

The procedure followed in this application is as follows: 

 First step:  support preparation

General Cleaning: removing with vacuum of dust, dirt and other material generated during earlier work and that may prevent optimal adhesion to the substrate. 

Second step:  Tecnocoat P-2049 system application

the  Tecnocoat P-2049  system used on this project is constituted by: 

• primer Tecnocoat Primer PU: applied with a roller over the entire surface, improves the adhesion of the existing support and avoid the presence of trapped air. 
• membran  Tecnocoat P-2049: Tecnocoat polyurea membrane 100% pure, continuous and fully bonded to the support, is applied by spraying equipment as graco E-XP2, by an instantly control of mixture,  temperature and pressure of the liquid components. It is applied directly on the primer, in many continuous layers until the thickness required by our document ETA 11/0357.

Constraints and issues that have decided the agency AENA chose to use the Tecnocoat P-2049 as polyurea waterproofing system were as follows: 

• Optimal sealing of the entire metal surface in a continuous manner with excellent adhesion 
• Fast excution for air traffic .  
• Safety of the choosed system  mostly  for  protection and waterproofing .
