Application
Ambient air temperature
+10 °C min. / +35 °C max.
Relative air humidity
80 % max.
Dew point
Beware of condensation!
The substrate must be at least +3 °C above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the floor finish. Be aware that the substrate temperature may be lower than the ambient temperature.
Substrate temperature
+10 °C min. / +35 °C max.
Substrate moisture content
Moisture content of concrete substrate must be ≤ 4% by mass (pbw – part by weight) as measured with a Tramex® CME/CMExpert type concrete moisture meter on mechanically prepared surface according to this product data sheet (preparation to CSP-3 to CSP-4 as per ICRI guidelines). Do not apply to concrete substrate with moisture levels > 4% mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter. If moisture content of concrete substrate is > 4% by mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter, use Sikafloor 81 EpoCem

Waiting time / Overcoating
Before applying Sikafloor®-264 HC N on Sikafloor®-161 HC allow:
Substrate temperature | Minimum | Maximum |
+10 °C | 24 hours | 3 days |
+20 °C | 12 hours | 2 days |
+30 °C | 08 hours | 1 day |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

Consumption
Build-up | Product | Consumption |
Primer | Sikafloor®-161 HC | 0.30–0.50 kg/m2 |
Self-smoothing | 1 pbw Sikafloor®-264 HC N | 1.6 kg/m2 |
Filler | 1 pbw quartz sand (01 - 0.3 mm) | 1.3 kg/m2 |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, type of filler, variations in level and wastage etc. Please consult with Sika representative in case application is at lower temperature (< 15 °C).
EQUIPMENT
Sikafloor®-264 HC N must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment. For the preparation of mortars use a forced action mixer of rotating pan, paddle or trough type. Free fall mixers should not be used
SUBSTRATE QUALITY
- The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm2) with a minimum pull off strength of 1.5 N/mm2.
- The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc.
- Weak concrete must be removed and surface defects such as blow holes and voids must be fully exposed.
- Repairs to the substrate, filling of blowholes/voids and surface levelling must be carried out using appropriate products from the Sikafloor®, Sikadur® and Sikagard® range of materials.
SUBSTRATE PREPARATION
Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured surface.
All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum.
MIXING
Prior to mixing, stir part A mechanically. Add coloue incase colour component is seperate item. When all of part B has been added to part A, mix continuously for 1 minute until a uniform mix has been achieved. Then gratually add quartz filler & mix for another 2–3 minutes to get hogenious mix. De-can whole mixed materials to another container & mix for a further 1 minute to achieve consistent mix & avoid any lumps or unmixed particle in the container. Over mixing must be avoided to minimize air entrapment.
APPLICATION
Primer
Primer can be applied to the prepared substrate using a squeegee and back roll to provide uniform coverage. Ensure that the substrate is pore-free and pinhole free and provides uniform and complete coverage over the entire substrate. If necessary, apply an additional coat to ensure the substrate is pore-free and pinhole-free and provides uniform and complete coverage over the entire substrate.
Self-smoothing topping
Pour the mixed materials on to the dried primed substrate & spread by pin rack or hand notch trowel & back roll with spike roller for leveling & de-airing.
CLEANING OF TOOLS
Clean all tools and application equipments with suitable solvent immediately after use. Hardened and/or cured material can only be removed mechanically.
CLEANING
To maintain the appearance of the floor after application, Sikafloor®-264 HC N 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 cleaning agent.
Refer to Sika cleaning & maintenance guideline & consult with Sika representative.
