The Lotte Castle is one of the most prefered apartment in South Korea. The award-winning designs are setting the standard for luxury living. The Lotte Castle brand Has won “the Best Apartment Brand Voted by Women Consumers” award for five consecutive years.

When Lotte Castle President Apartments were originally designed, Latapoxy by Laticrete was specified. However, in the past Lotte Engineering & Construction had issues with the performance of locally manufactured grouts when installing natural tile and stone installations. Lotte Engineering & Construction was very hesitant to use a product they had no experience with. This project demanded products with a solid reputation and performance capabilities for the elegant facades at the sophisticated and urban Lotte Castle President Apartments.


  • Grout for 15,000m2 (161,459 ft2) of natural stone
  • Expedited installation time frame
  • Laticrete products originally specified


By providing job references and support from the installers, the developer allowed ARDEX to test their materials for the project. ARDEX Korea offered a sensible, satisfactory and reliable solution for Lotte Engineering & Construction. After working with ARDEX Sales and Technical Support Teams to narrow the selection based on specific criteria for the installation, ARDEX FG 8 Flexible colored grout for tile was specified and ultimately selected by the developer for Lotte Castle President Apartments.

ARDEX FG 8 is a polymer fortified, flexible cement-based grout designed for floor and wall installations. It also reduces the likelihood of a cracking failure from building movement. ARDEX FG 8 is easy to maintain because it is water and mold resistant, and dries to a smooth finish that reduces the amounts of trapped pollutants. The grouts’ improved color integrity keeps the installation true to the original design, ensuring the quality of the color palette remains consistent throughout the entire installation.

Through their dedicated employees, superior sales and technical support team, and proven track record, ARDEX once again proves it has the products to get the job done right, the first time… every time!
