Baytec Spray chosen for "Metropol Parasol" project in Seville

As part of the project, an area of around 10,000 m2 of the Plaza de la Encarnación has been covered over with a multifunctional sunshade, spanning the square at a height of more than 20 m. To implement the concept, the most economical solution proved to be a hybrid construction consisting of steel tensioning elements and convex, three-dimensional grid-like structures made of wood.The wooden structure is made from laminated veneer panels up to 16 m long with a diameter of 7 cm. The total volume of timber is 3,500 m3. Apart from offering protection from the weather, the 3 mm thick polyurethane coating also contributes to the homogeneous appearance for the six parasols. To apply the coating, the liquid raw material components were first mixed in a mobile spraying machine. The coating solidified just a few minutes after application, but remains permanently elastic.According to the company, Baytec Spray is free of solvents, plasticisers and mineral fillers, and offers lasting and reliable protection for wood, concrete and metal. The flame-retardant system used in Seville is characterised by its good adhesion to the primer on which it is applied and for its long-term crack bridging behaviour. Although the spray-on system is water-impermeable, it has good water vapour permeability, says BMS.
