The colour of the Sikafloor®-327 has to be approximately adjusted to the colour of the Sikafloor®-305 W seal / top coat.
Applied colours selected from colour charts will be approximate. For colour matching: Apply colour sample and confirm selected colour under real lighting conditions.
When product is exposed to direct sunlight, there may be some discolouration and colour variation, this has no influence on the function and performance of the floor finish.

Application
Mixing Ratio
Part A : part B = 81:19 (by weight)
Layer Thickness
2.80 kg/m² - film thickness ~ 2.0 mm
Refer to the respective System Data Sheet.
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.
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).
Pot Life
Temperature | Time |
+10 °C | ~ 25 minutes |
+20 °C | ~ 20 minutes |
| +30 °C | ~ 15 minutes |
Curing Time
Before overcoating Sikafloor®-327 allow:
Substrate temperature | Minimum | Maximum |
+10 °C | 24 hours | 72 hours |
+20 °C | 18 hours | 48 hours |
+30 °C | 16 hours | 36 hours |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
If maximum waiting time is exceeded, exposed surface of Sikafloor®-327 has to be grinded to achieve mechanical bonding between the layers of Sikafloor®.

MIXING
Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 2 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 minimise air entrainment.
Mixing Tools
Sikafloor®-327 must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.
APPLICATION
Prior to application, confirm substrate moisture content, relative humidity and dew point.
Sikafloor®-327 is poured and spread evenly by means of a serrated trowel or pin rake. When used in a self smoothing system, roll in two direction with a spike roller to ensure even thickness and to remove entrapped air.
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.
