Tal supplies adhesive for large-format tile installation for hyundai showroom

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.

The Professional Contractor’s Heavy Duty Manual Tile Cutter is designed for effortless and accurate cutting of larger-format tiles. Features include a cutting head carriage with ball bearings for high-precision cutting, a balancing arm to support larger tiles during use, and a large graduated swivelling cutting guide. This version is available in 750 mm and 900 mm versions.

The Professional Contractor’s Tile Cutters from TAL are of a heavy-duty design and construction, specifically for daily use on-site.

At TAL, we offer a 10-year warranty on any tiling installation – provided that both the Materials and Methods specifications are strictly followed and that the installation is carried out by a registered TAL tiler, while being monitored by a TAL representative. This is how we ensure that our clients receive a high-quality, lasting installation within the time they have to complete their tiling project.

Paying attention to these 4 key points when installing your new carpets will ensure that your investment is long-lasting and adds value to your home.

When  using  large  format  tiles (a  tile  with  the  length of at least  one  edge equal to/greater  than  600mm, or a facial area greater than  3500cm²) there will be a smaller number of grout joints, compared with the same area of normal format tiling. As a result, less stress (movement) can be accommodated at tile joints.

Complete the waterproofing system by replacing the water in the grout mix with TAL Bond, a latex additive, as this further increases the water resistance and flexibility of the installation.

Get the job right the first time and avoid future headaches from water seeping through and damaging the walls and floors of your home. The additional cost and effort of properly waterproofing your shower is an investment in your property and will ensure a beautiful and functional bathroom for years to come.

STEP 8

Roll the area using a TAL Spiked Roller to facilitate the release of any trapped air to produce a smooth surface, and to allow it to dry.

Allow the screed installation to dry for 24 hours before subjecting to foot traffic (or other trades) or installing floor coverings.

TAL MOSAICFIX is available in 20 kg and 5 kg bags from leading retail outlets. 

Designed to be 100% compatible, using the TAL range of products ensures fully guaranteed multi-level tiling systems from a single source. TAL products are manufactured in South Africa to suit local climatic conditions.

If you are in any doubt, contact the TAL Technical Advisory Service on 0860 000 TAL (825), email [email protected]. Alternatively, employ the services of an experienced and skilled mosaic tiling contractor.

When replacing tiles, it is not always possible to apply the TALFIX directly to the floor, in which case apply the adhesive in a solid bed onto the back of the tile, ensuring complete coverage. Gently trace the notched side of a floor trowel through the adhesive to create ‘ridges’.

Adhesive system

When tiling onto existing tiles, it is important to only use a quick- or rapid-setting adhesive, as the existing tiles will present a dense, impervious surface, and standard-setting adhesives will take longer to dry. Too early trafficking of newly-installed tiles before the adhesive has set sufficiently can result in hollow-sounding or loose tiles.

Use TAL Tile-To-Tile quick-setting adhesive for tiling onto interior surface beds. When tiling onto suspended slabs and for external installations mix the TAL Tile-To-Tile with TAL Bond, replacing the water in the mix. Alternatively, TAL Bond Powder can be added to the adhesive mixing water.

Ensure that there is a solid bed of adhesive at least 6 mm thick beneath each tile.

Back buttering with a thin coat of adhesive may also be required when using large-format tiles to ensure full contact with the adhesive bed.

Grouting

Grouting should not be carried out until the adhesive has set sufficiently to prevent the tile installation from being disturbed during the grouting operation (always refer to the adhesive packaging for setting times). When using TAL TAL Tile-To-Tile, allow a minimum of six hours before grouting.

For interior surface beds, use TAL Wall & Floor Grout for filling tile joints up to 8 mm wide. TAL Quarry Grout can be used in wider joints up to 25 mm wide. On suspended slabs and for external installations, replace the water in the grout mix with TAL Bond, or add TAL Bond Powder to the grout mixing water.

Particular care must be taken to clean the grout off the tile face before it hardens completely. This is especially important when an additive such as TAL Bond or TAL Bond Powder has been used. A tile sample should be tested beforehand to ensure that no grout is absorbed through the glaze or into the tile body, thereby staining the tiles permanently.

Movement joints

The lack of movement joints in tile installations is a major cause of tile failure. When tiling over existing tiles, the existing structural and movement joints must be maintained in the new tile installation. The movement joints should be at least 5 mm wide and extend through the adhesive and both tile layers.
