Sika Sikafloor 2 SynTop is a one part, pre-blended, coloured synthetic dry shake hardener for concrete comprising of cement, hard aggregates, compatible admixtures and pigment. For use on fresh, wet concrete.
Sika Sikafloor 2 SynTop provides a hard wearing, non metallic dry shake topping for monolithic floors. When sprinkled and trowelled into fresh wet concrete floors,
it forms a coloured, very wear resistant smooth surface. Typical uses are in warehouses, distribution centres, factories, manufacturing facilities, aircraft hangars, DIY
stores, supermarkets, shopping malls, offices and museums.
- Very high wear resistance rating
- Good impact resistance
- Cost effective, long life floor
- Maintenance free
- Slip resistant surface possible
- Dust proof
- Increased resistance to oils and grease
- Available in colours
Sika Sikafloor 2 SynTop may only be used by experienced professionals.
The concrete deliveries must be of consistent quality and comply with local standards. Concrete characteristics are specified by its class determined in the static design and by general recommendations for concrete mix design. W/C- ratio must not be to too low as some water is required for hydration of the Sikafloor®-2 SynTop. Generally recommended w/c-ratios are between 0.45 and 0.55 and must be consistent while being poured. The compressive strength must be a minimum of 25 N/mm2.
Use of Sikament® or Sika Viscocrete® super plasticisers is advised to ensure the optimum quality of concrete and where fibres are used, their optimum dispersion
within the mix. Air entrained concrete is not a suitable substrate for the application of dry shake hardeners.
Mechanical Application - Automatic spreader in conjunction with a laser screed. Spread Sikafloor®-2 SynTop evenly onto the concrete immediately after screeding at ~5 kg/m2 in one application.
Manual application - Dependent on the conditions, remove the surface “bleed” water or allow it to evaporate. Sprinkle Sikafloor ®-2 SynTop onto the screeded concrete evenly in 2 stages (first stage: 3 kg/m2; second stage: 2 kg/m2). Care must be taken to apply the product without creating ripples etc. in the concrete surface.
Compaction: The first application must be worked into the slab followed immediately by application of the second stage quantity of Sikafloor®-2 SynTop. Notes:
Never add water to the surface where the dry shake has been applied.
Sikafloor®-2 SynTop results in the slab surface becoming “stiff” more quickly than usual. Careful trimming must take place along the edges where adjoining slabs are to be poured. Final finishing for closing pores and removing undulations can be achieved either by hand or powered trowel.
Application time for dry shake products is influenced by every variable which affects the placing of concrete, and can therefore vary substantially, depending on the
prevailing conditions. For mechanical application with automatic spreader and laser screed, the spreading can start almost immediately after concrete has been levelled to allow for the hydration of the dry shake. Compaction with the trowel can start as soon as weight of the power trowels is supported by the concrete.
For manual application, the dry shake must be spread once the concrete can be stepped on, without leaving a print deeper than 3–5 mm. Periodical checking of the condition and development of the concrete will determine the correct time frame for each stage and sequence of application.
Cure and seal Sikafloor®-2 SynTop immediately after finishing using a curing compound from the Sikafloor® ProSeal range. (Refer to relevant Product Data Sheet).
Joints: After finishing operations and completing saw cuts, clean off any residual saw lubricant / slurry without delay. Joints can be filled with Sikaflex® PRO-3 or another appropriate Sikaflex® sealant in accordance with the floor design requirements.
