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).

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage etc.
MIXING
Prior to mixing stir part A mechanically. When all of part B has been added to part A, continuously mix 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 consistent mix.
Over mixing must be avoided to minimize air entrainment.
MIXING TOOLS
Sikafloor®-264 HC 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.
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 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/-160 HC by brush, roller or squeegee. Preferred application is by using a squeegee and then backrolling crosswise.
Levelling
Rough surfaces need to be levelled first. Therefore use e.g. Sikafloor®-161 HC levelling mortar (see PDS).
Coating
Sikafloor®-264 HC as coating, can be applied by short-piled roller (crosswise).
Seal Coat
Sealer coats can be applied by squeegee and then back-rolled (crosswise) with a short-piled roller.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with Thinner C 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 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.
