In creating the Koahsiung Rapid Transit System (KRTS), the Koahsiung Rapid Transit Corporation (KRTC) hoped to increase development to the Kaohsiung region in south Taiwan. Eventually, they realized high quality design should be beautiful and functional if it is going to attract attention. The KRTC incorporated art into the trasit station to support public art and become a driving force in bettering the surrounding community. Part of this art installation included a high quality mosaic design that was pieced together with the assistance of ARDEX products. Since the temperature was extremely humid, a thinset with a sufficient open time and extended pot life was needed.
• Mosaic tile design on floors, walls and statues (360 m2 / 3875 ft2)
• Humid and hot environment
Mosaic tiles were to be installed on the concrete floors, enamel walls and decorative statues. Through the use of design maps, the installation was quickly implemented using ARDEX STS 8 Superior Tensile Strength Tile Adhesive and ARDEX E90 Mortar Admix. High humidity allows for limited working time and causes tile adhesives to set up extremely fast. Since the humidity in the air was extremely high, workers needed to install the tile quickly. The use of design maps allowed the workers to cut the tiles into the desired shapes and expedite the installation.
Each substrate was initially treated with ARDEX ABA 662.V General Purpose Emulsion Base Primer to create a strong bond for the tile adhesive without a need for mechanical treatment. ARDEX ABA 662.V is used to seal absorbent, porous substrates and improve the adhesion of ARDEX Tile Adhesives. ARDEX ABA 662.V can be used indoors and outdoors, for residential or commercial applications and on walls or floors because it is fast drying and contains no hazardous solvents. Once the ARDEX ABA 662.V dried, Hommounkang Mosaic Studio applied a slurry of the ARDEX STS 8 Superior Tensile Strength Tile Adhesive with ARDEX E 90 Mortar Admix. Using this product combination increased the bond strength between the tile and the substrate.
Once tiles were placed, ARDEX recommended two types of grout: ARDEX ABA 680.J Cement-Based Tile Grout for indoor installations and ARDEX ABA 695.J Polymer Modified Cement-Based Grout for outdoor installations. ARDEX ABA 680.J and ARDEX ABA 695.J can be used with every type of tile, and are especially suited for tile installations with joint widths of 5 to 10 mm wide, as there is no shrinkage when drying. ARDEX ABA 695.J is ideal for outdoor installations because it is mold resistant, water repellant and does not trap dirt. These properties improve the likelihood that the tile artwork would not become damaged over time from outdoor weather conditions in a tropical climate. Both grouts are available in a wide range of colors to further customize installations and can be used for indoor and outdoor installations.
