The product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +10 °C and +30 °C.

All Density values at +23°C.

~100%

Resistant to many chemicals. Contact Sika technical service for specific information.

Part A : part B = 79 : 21 (by weight)

+10 °C min. / +35 °C max.

80 % r.h. max.

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

+10 °C min. / +35 °C max.

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

Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

Note: Times are approximate and will be affected by changing ambient conditions.

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage etc.
Please consult with Sika representative in case application is at lower temperature (Less than 15Deg.C)

Pre - mix is recommended for component A & colour component one day prior to application. Prior to mixing, stir part A mechanically when all of part B has been added to part A, mix continuously for 2-3 minutes until a uniform mix has been achieved. 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 entrainment.

MIXING TOOLS

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.

Prior to application, confirm substrate moisture content, relative air humidity and dew point. If > 4 % pbw moisture content, Sikafloor® EpoCem® may be applied as a T.M.B. (temporary moisture barrier) system.

Primer
Make sure that a continuous, pore free coat covers the substrate. If necessary, apply two priming coats. Apply Sikafloor®-161 HC by brush, roller or squeegee. Preferred application is by using a squeegee and then back rolling crosswise.
Levelling
Rough surfaces need to be levelled first. Therefore use e.g. Sikafloor®-161 HC levelling mortar (see PDS).
Coating
Sikafloor®-264 HC N as coating, can be applied by shortpiled roller (crosswise).
Seal Coat
Sealer coats can be applied by squeegee and then back-rolled (crosswise) with a short-piled roller.

Self smoothening
Sikafloor®-264 HC N as self smoothening topping can be applied by pin rack, notch trowel back roll with spikeroller crosswise.

Clean all tools and application equipment with Thinner C or suitable solvent immediately after use. Hardened and/or cured material can only be removed mechanically.

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 detergents and waxes.
