Application
Ambient Air Temperature
+10 °C min. / +30 °C max.
Relative Air Humidity
During curing the humidity should not exceed 75 % max. Adequate fresh air ventilation or a dehumidifier must be provided to remove the excess moisture from the curing product.
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).
Waiting Time / Overcoating
Before applying Sikafloor®-327 on Sikafloor®-156/160/161 allow:
Substrate temperature | Minimum | Maximum |
+10°C | 24 hours | 4 days |
+20°C | 12 hours | 2 days |
| +30°C | 8 hours | 1 days |
Before applying Sikafloor®-305 W ESD on Sikafloor®-327 allow:
Substrate temperature | Minimum | Maximum |
+10°C | 24 hours | 72 hours |
+20°C | 12 hours | 48 hours |
| +30°C | 6 hours | 36 hours |
Before applying Sikafloor®-305 W ESD on Sikafloor®-305 W ESD allow:
Substrate temperature | Minimum | Maximum |
+10°C | 48 hours | 10 days |
+20°C | 24 hours | 8 days |
| +30°C | 16 hours | 7 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Applied Product Ready for Use
Temperature | Foot traffic | Light traffic | Full cure |
+10°C | ~ 48 hours | ~ 5 days | ~ 10 days |

Consumption
Coating | Product | Consumption |
Primer | Sikafloor®-156/-160/-161 | 1-2 x ~ 0.3 - 0.5 kg/m² |
Levelling (if required) | Sikafloor®-156/-160/-161 levelling mortar | Refer to PDS of Sikafloor®-156/-160/-161 |
| Base coat | Sikafloor®-327 | ~ 2.1 kg/m² (1.5 mm) |
| Earthing connection | Sika® Earthing Kit | 1 earthing point per approx. 200 -300 m², min. 2 per room. |
Final conductive coating | Sikafloor®-305 W ESD | 1-2 x 0.18 – 0.2 kg/m²/layer |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage etc. When used in high wear conditions, e.g. castor chairs, a second layer with Sikafloor®-305 W ESD improves the mechanical properties of the floor covering. Lower consumption can cause roller marks, gloss differences and irregular surface structure, higher consumption result in water retention and can cause pigment floating as well as unsatisfactory conductivity.
