Application
Ambient Air Temperature
+10 °C minimum / +30 °C maximum
Relative Air Humidity
During curing the humidity should not exceed a miximum of 75 %. 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 minimum / +30 °C maximum
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
Sikafloor® MultiDur ES-43 ESD System
| Coating | Product | Consumption |
| Primer | Sikafloor®-150/151 | 1-2 x ~ 0.3 - 0.5 kg/m² |
| Levelling (if required) | Sikafloor®-150/151 levelling mortar | Refer to PDS of Sikafloor®-150/151 |
| Earthing Connection | Sika® Earthing Kit | 1 earthing point per approximately 200 -300 m², minimum 2 per room. |
| Conductive Primer | Sikafloor®-220 W Conductive | 1 x 0.08 - 0.10 kg/m² |
| Conductive Base Coating | Sikafloor®-262 AS N filled with quartz sand F34* | Maximum 2.5 kg/m² Binder + quartz sand F 34: 1 : 0.1 pbw to 1 : 0.3 pbw (depending on the air temperature the filling grade varies) |
| Final ESD 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 or wastage etc.
*All values have been determined using quartz sand F 34 (0.1-0.3 mm) from Quarzwerke GmbH Frechen. Other quartz sand type will have an effect on the product, such as filling grade, levelling properties and aesthetics of the conductive base coat. Generally, the lower the temperature the less the filling grade. 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.
