The Hyundai showroom in Weltevreden Park installed large format porcelain tiles – and TAL supplied the adhesives and ancillary products for the installation.

The area would be exposed to frequent heavy-traffic, which meant that vitrified porcelain tiles, a fast-track installation and a rapid-setting adhesive system would be required. JRRA Tiling installed tiles for a floor space of 1500m² and TAL supplied TAL Pourable Adhesive to install 600x600mm grey porcelain tiles to the showroom floor. Car showrooms require high-strength, rapid-setting, flexible adhesives for large-format tile installations. Using TAL Pourable Adhesive with its rapid-setting and flexible characteristics ensures solid bedding for the tiles, while saving on site contractors a decent amount of time. Hyundai’s tile installation was carried out on a powerfloated concrete floor. As no primer is required due to the polymer-modified formulation, the contractor was able to apply TAL Pourable Adhesive  directly to a clean, dry substrate.

With modern manufacturing techniques, the production of porcelain and ceramic tiles in various sizes is readily available. For this reason these tiles need special consideration in case of permissible manufacturing tolerances. These large-format tiles may have a permissible surface flatness irregularity which means that the tile’s surface could be curved or ‘bowed’. Another concern with these tiles is ‘lipping’. Especially when laid in a brick-bond pattern, so the tiles will require a level, flat substrate and specific joint widths. Back buttering (using a thick coat of adhesive) usually ensures full contact and the solid bed of adhesive needed behind each tile.

TAL Pourable Adhesive is a grey, pourable, flexible rapid-setting high-strength cement-based adhesive, specially formulated to provide good wet-out on large format tiles ensuring solid bedding with no buttering required on the tile backs. The adhesive is suitable for fixing all large-format ceramic, porcelain, granite, dark-coloured marble and natural stone tiles to floors because it enables fast and easy bedding of floor tiles. The product’s rapid-setting flexible formulation means that no latex additive is required for installations in wet areas, exterior applications and surfaces where normal building movement is expected. 

In addition to using a flexible adhesive, tile movement joints were also required at three-metre intervals in both directions to allow for the anticipated movement in the installation. Depending on the site conditions and workmanship he adhesive’s coverage is approximately 8kg/m². The tiled floor could handle light traffic after four hours, at which point it can be grouted, and normal traffic after six hours.

TAL also supplied TAL Goldstar 12 and TAL Bond, a latex additive, to fit porcelain tiles to the back of houses and external areas. A white 200x200mm ceramic wall tile was fitted in the bathrooms at Hyundai.
