Usage
Sikafloor®-3 QuartzTop provides a hard wearing, mineral dry shake topping for monolithic floors. When sprinkled and trowelled into fresh wet concrete floors, it forms a wear resistant smooth surface.Typical uses are in warehouses, factories, shopping malls, public areas, where wear durable and wear resistant floor is the key requirement.Advantages

The above values are dependant upon the concrete reaching its design strength for serviceability and will be affected by changing ambient conditions, particularly temperature and relative humidity.
Consumption
~3–5 kg/m2.
the consumption will depend on application method and the concrete mix (w/c-ratio) This figure does not allow for surface profile and wastage.
SUBSTRATE QUALITY
The concrete deliveries must be of consistent quality and comply with local standards. Concrete characteristics are specified by its class deteremined 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®-3 QuartzTop 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.
APPLICATION
Mechanical Application - Automatic spreader in conjunction with a laser screed Spread Sikafloor®-3 QuartzTop evenly onto the concrete immediately after screeding at 3-5 kg/m2 in one application.
Manual application Dependent on the conditions, remove the surface bleed water or allow it to evaporate. Sprinkle Sikafloor®-3 QuartzTop 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. Casting Sikafloor®-3 QuartzTop powder carelessly or further than 2 metres from point of casting will reduce the consistency of finish. Compaction: The first application must be worked into the slab followed immediately by the application of the second stage quantity of Sikafloor®-3 QuartzTop. Notes:
- Never add water to the surface where the dry shake has been applied.
- Sikafloor®-3 QuartzTop 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 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 the concrete has been levelled to allow for the hydration of the dry shake. Compaction with the trowel can start as soon as the 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.
CURING TREATMENT
Cure and seal Sikafloor®-3 QuartzTop immediately after finishing using using a curing compound, Sikafloor® ProSeal W or Sikafloor® ProSeal-22. (Refer to relevant Product Data Sheet). The sealers additionally harden the surface, decrease dust and reduce liquid absorbtion. 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.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
CLEANING
To maintain the appearance of the floor after application, Sikafloor®-3 QuartzTop must have all spillages removed immediately and must be regularly cleaned using rotary brush, mechanical scrubbers, scrubber dryer, high pressure washer, wash and vacuum techniques, etc., using suitable detergents and waxes.
