Application
Mixing Ratio
Part A : part B = 79 : 21 (by weight)
Ambient Air Temperature
+10 °C min. / +30 °C max.
Relative Air Humidity
80 % r.h. max.
Dew Point
Beware of condensation!
The substrate and uncured floor must be at least 3 °C above dew point to reduce the risk of condensation or blooming on the floor finish.
Note: Low temperatures and high humidity conditions increase the probability of blooming.
Substrate Temperature
+10 °C min. / +30 °C max.
Substrate Moisture Content
≤ 4 % pbw moisture content.
Test method: Sika®-Tramex meter, CM-measurement or Oven-dry-method.
No rising moisture according to ASTM (Polyethylene-sheet).

Consumption
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc. For detailed information, refer to the System data sheets Sikafloor® MultiDur ES-15 and Sikafloor® MultiDur ES-21.

MIXING
Coatings
Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 3 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into another container and mix again to achieve a smooth consistent mix. Over mixing must be avoided to minimise air entrainment.
Self-Smoothing Resin
Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 3 minutes until a uniform mix has been achieved. When parts A and B have been mixed, add the quartz sand and if required Extender T. Mix for a further 2 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into another container and mix again to achieve a smooth consistent mix. Over mixing must be avoided to minimise air entrainment.
Mixing Tools
Sikafloor®-264 ZA (unfilled) must be thoroughly mixed using a low speed electric stirrer (300–400 rpm) or other suitable equipment. For the preparation of a self- smoothing resin, use a forced action mixer or rotating pan, paddle or trough type. Free fall mixers should not be used.
APPLICATION
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 temporary moisture barrier (T.M.B.) system.
Primer
Ensure a continuous, pore free coat covers the substrate. If necessary, apply two priming coats. Apply Sikafloor®-161 by brush, roller or squeegee.
Preferred application is by using a squeegee and then back rolling in two directions at right angles to each other.
Levelling
Rough surfaces need to be levelled first. Therefore use e.g. Sikafloor®-161 levelling mortar (see PDS).
High Build Smooth Coating
Sikafloor®-264 ZA can be applied using a short-piled roller in two directions at right angles to each other.
Self-Smoothing Finish
Sikafloor®-264 ZA is poured and spread evenly using a suitable trowel/pin rake to the required thickness.
Spike roller immediately in two directions at right angles to each other to remove trowel marks, aid air release, ensure an even thickness and obtain required surface finish.
Slip Resistant Broadcast Coating
Apply a scratch coat to substrate and immediately broadcast with quartz sand to excess to produce an even distribution surface profile. Allow scratch coat to initially cure and remove all loose sand by vacuum equipment. Apply a final seal/top coat of Sikafloor®-264 ZA. For application onto damp substrates, refer to Sikafloor® MultiDur EB-12 ECC system data sheet for primer and levelling product changes.
Seal coat
Apply seal/top coat of Sikafloor®-264 ZA by squeegee at a consumption of 0,4–0,6 ltr/m2 to completely encapsulate the sand. Then using a short-piled roller, back roller in two directions at right angles to each other.
CLEANING OF TOOLS
Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
