Tal stoneflow specified for unique flooring project at greenstone shopping centre

A one-of-a-kind floor designed for the refurbishment of the food court at Greenstone Shopping Centre in Edenvale, Johannesburg, was installed using TAL StoneFlow, a fast track, industrial, terrazzo-look decorative flooring system.

The highly-detailed food court floor, designed by architects Bentel Associates International, entails the transformation of the existing floor into an eye-catching design of large butterflies, ladybirds and dragonflies, using coloured glass aggregates embedded into the seamless, polished screed.  

Whilst polished, decorative and seamless concrete floor solutions are in high demand, these terrazzo floors can take up to 28 days to cure before grinding and polishing can commence.

Rapid-setting TAL StoneFlow however, is polishable within four hours of installation, and is designed to produce a durable and hard-wearing surface, which is very well suited for this high foot-traffic area in the shopping centre. Furthermore, the product is shrinkage-compensated, durable and abrasion-resistant, and its seamless, smooth, noise-reducing substrate is easy to maintain. It is especially designed for use in industrial environments, on both new construction and renovation projects. It is designed for applications exposed to heavy traffic and abrasion, such as factories, warehouses and production areas. It is also suitable for commercial and residential applications.

As a cement-based, self-smoothing, heavy-duty decorative screeding system, TAL StoneFlow is available in a wide range of colours and aggregate finish. To achieve the desired aesthetic, the products and aggregates chosen for this project, were manufactured and supplied to specified RAL colours. The unique floor was installed by TAL approved applicator, ThinkFlood Flooring Specialists.

Also ensure that the spacer size you use is correct for the type of tile you have selected; the joint width between glazed ceramic floor tiles should be a minimum of 5mm wide, and a minimum of 3mm wide between porcelain tiles, including rectified porcelain tiles. To achieve the natural look, opt for grout colour that is darker than the tile itself. Click here to find out more about how to select the perfect grout colour.  

MOVEMENT JOINTS

Allowance for movement (building, thermal and moisture) must be made in all tile installations. Perimeter joints must be installed around the perimeter of all floors and around any fixtures protruding through the tile installation, such as walls, columns and stairs. Intermediate tile panel movement joints should also be installed at maximum 5 metre centres in both directions for interior surface bed applications, and maximum 3 metre centres for suspended slabs and exterior applications. These  joints must be a minimum of 5mm wide, must extend through the tile and tile adhesive layers to the substrate, and must be filled with a good quality resilient joint sealant and suitable backing cord.

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.
