[Construction Example 15] Renovation of the gymnasium's exterior walls with granite-like exterior materials for extended durability.
The exterior walls of the public facility (gymnasium) were renovated with high weather-resistant "JX" in a granite-like finish and "JT-S" in a granite-like design, following the existing image.
We would like to introduce an example of the renovation of the exterior walls of an existing sprayed tile-finished public facility (Kobe City Central Gymnasium) using three colors of "JX" (for the large columns) with a granite-like finish and "JT-S" (for other exterior walls). 【Property】 [Renovation] Kobe City Central Gymnasium (Kobe City, Hyogo Prefecture) ◇ Construction Date: May 2019 ◇ Construction Area: 7,479m2 (JX: 2,469m2, JT-S: 5,010m2) ◇ Base Material: Sprayed Tile 【Customer's Issues and Requests】 ◆ They want to reduce the frequency of exterior wall painting renovations without changing the current design and lower maintenance costs. ◆ A long-lasting type of coating material that can maintain the aesthetic of the exterior walls for a long time is desired. 【Adoption Background】 ◇ Initially, the plan was to apply our product only to the large columns, but after consulting with the client (Kobe City), they expressed a desire to have the same warranty period for the other exterior walls, leading to a re-proposal and a full-scale application. 【Selection Points】 ◆ A long-lasting exterior finish material with a 20-year warranty that excels in durability and weather resistance. ◆ The dedicated topcoat excels in weather resistance, durability, and dirt resistance, maintaining a beautiful wall surface for an extended period. ◆ It significantly reduces regular maintenance costs due to its excellent durability and weather resistance, thereby lowering the building's life cycle cost (LCC).
