Sikafloor®-2 SynTop-2
Sikafloor®-2 SynTop-2 is one part, preblended, synthetic dry shake hardener for concrete comprising of cement, hard corundum aggregate, and compatible admixtures.
- Very high wear resistance
- Impact resistance
- Cost effective, long life floor
- Maintenance free
- Slip resistance surface possible
- Dust proof
- Increased resistance to oils and grease
Usage
- Sikafloor®-2 SynTop-2 provides a hard wearing, dry shake topping for monolithic floors. When sprinkled any trowelled into fresh wet concrete floors, it forms a wear resistant smooth surface.
- Typical users are in warehouses, distribution centers, factories, industrial facilities, aircraft hangars, DIY stores, supermarkets, shopping malls, offices and museums.

Storage conditions
Store in dry conditions at temperatures between +5 °C and +30 °C.
Application
Ambient air temperature
+5 °C Min, +35 °C Max
Relative air humidity
Rel. air-humidity : minimum 30% ; maximum 98%
Watch out for efflorescence at low humidity.
Watch out for slow bleeding, slower curing and hardening and slower power-floating operations at high humidity
Applied product ready for use
Substrate temperatur | Foot trafic | Fully serviceable |
+10 °C | 18 h | 10 d |
+20 °C | 12 h | 7 d |
+30 °C | 8 h | 5 d |
The above values are dependant upon the concrete reaching its design strength for serviceability and will be affected by changing ambient conditions.
Consumption
~5 kg/m² - 12 kg/m²
SUBSTRATE QUALITY
The concrete deliveries should be of consistent quality. A concrete slump in the range 75 to 110 mm will normally give best results. The slab should be of good quality concrete with a minimum water / cement ratio consistent with the production of a fully compacted slab. The compressive strength should be a minimum of 25 N/mm². Use of Sikament or Sika ViscoCrete super-plasticizers is advised to ensure the optimum quality of concrete and where fibres are used, their optimum dispersion within the mix.
APPLICATION
Automatic spreader in conjunction with a laser screed:
Spread Sikafloor®-2 SynTop-2 evenly onto the concrete immediately after screeding at 5 kg/m² (example consumption) in one application.
Manual application:
Allow the surface “bleed” water to evaporate. Sprinkle Sikafloor®-2 SynTop-2 onto the screeded concrete evenly in 2 stages.
(first stage: 3 kg/m², second stage: 2 kg/m²) (Example consumption)
Care should be taken to apply the powder to avoid creating ripples etc. in the concrete surface. Overall application rate 5 kg/m². Casting Sikafloor®-2 SynTop-2 powder carelessly or further than 2 metres from point of casting will reduce the consistency of finish.
Compaction:
The first application should be worked into the slab followed immediately by application of the second stage of Sikafloor®-2 SynTop-2.
Curing:
Cure and seal Sikafloor®-2 SynTop-2 immediately after finishing using Sikafloor-ProSeal-22 (refer to separate data sheet).
Application time
Application time for dry-shake products is influenced by every variable which affects the placing of concrete, and will vary greatly depending on the particular 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 dryshake. Compaction with the trowel can start as soon as weight of the power trowels is supported by the concrete.
For manual application, the dryshake 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.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with water immediately after use.
Hardened/ cured material can only be mechanically removed.
