Built over a busy train station, the eight-story Lotte Department Store in Seoul, Korea would challenge most tile installations and wall renderings. A tile adhesive was needed that would absorb the trains vibrations and have a longer working time because of the high temperature in Seoul, Korea. ARDEX was asked to test their tile adhesives for the project. After a series of tests were completed, ARDEX tile adhesives were approved for the installation.

Lotte Engineering & Construction started by coating the installation surfaces with ARDEX ABA 660.V Acrylic Primer. An acrylic primer was specified for this project, because it not only creates a strong bond, but also for its flexibility. ARDEX ABA 660.V uses the most advanced acrylic polymer technology; it is totally resistant to re-emulsification in the hot humid conditions associated with the summer months in Korea.
In the areas to receive the tile installation, a combination of ARDEX STS 8 Superior Tensile Strength Tile adhesive and ARDEX E 90 Mortar Admix was applied. Developed for use in areas where movement is anticipated and over fibrous cement board, the combination of these two products creates a superior bond and offers increased flexibility.
Once the tiles were placed, the joints were filled with ARDEX FG 8 Flexible colored grout. ARDEX FG 8 was selected, because it is polymer fortified, making it flexible to resist cracking from the vibrations caused by the train station below. ARDEX FG 8 is mold and water resistant, and its smooth finish also reduces the amount of trapped pollutants, making it perfect for a busy department store installation.
To give the food court a luxurious feel, ARDEX PANDOMO® Wall was applied. ARDEX PANDOMO® Wall was the best choice for this installation because of its bond strength, and superior tensile strength. ARDEX PANDOMO® Wall can be customized to create a unique visual experience by selecting from various color options and textures. These properties help guarantee a long-lasting beautiful installation.
With the assistance of the ARDEX Sales and Technical Teams, Lotte Department Store can expect a beautiful, low maintenance installation that is proven to last over a long period of time.
