System Structure
Usage
It is used as:- Decorative and protective electrostatic conductive self-smoothing system for concrete or cement screeds with normal up to medium heavy wear.
- Suitable as a wearing course in industries, such as automotive, electronics and pharmaceutical manufacturing, storage facilities and warehouses.
- Particularly suitable for areas with sensitive electronic equipment e.g. CNC machinery, computer rooms, aircraft maintenance sheds, battery-charging rooms and areas subjected to high explosion risks etc.
Advantages
- Electrostatic conductive
- Good chemical and mechanical resistance
- Easy to clean
- Economical
- Liquid proof
- Semi-gloss finish
- Slip resistant surface possible
Colour
Almost unlimited choice of colour shades.
Due to the nature of carbon fibres providing the conductivity, it is not possible to achieve exact colour matching. With very bright colours (such as yellow and orange), this effect is increased. Under direct sunlight there may be some variations and colour variation, this has no influence on the function and performance of the coating.
Appearance
Self-smoothing system – gloss finish

System Structure
Sikafloor® MultiDur ES-24 ECF:
| 1. Primer + Earthing connection | Sikafloor®-150/-151+ Sika® Earthing Kit |
| 2. Conductive primer | Sikafloor® - 220 W Conductive |
| 3. Conductive final coating | Sikafloor® - 262 AS N filled with Sikafloor® Filler 1 |
Note: alternatively quartz sand F34* can be used as a filler, which will result in a gloss finish with a slight change of the aesthetical appearance.
The system configuration as described must be fully complied with and may not be changed.

| Self smoothing wearing course for high aesthetical demands film thickness ~1.5 mm | Sikafloor®-262 AS N filled with Sikafloor® Filler 1* | Maximum 1.6 kg/m² Binder + Sikafloor® Filler 1. Filling grade: 0.1 pbw to 1 : 0.2 pbw (Depending on the air temperature the filling grade varies) |
| Self smoothing wearing course film thickness ~1.5 mm | 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) |
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 and Sikafloor-Filler 1. Other quartz sand type will have an effect on the product, such as filling grade, levelling properties and aesthetics. Generally, the lower the temperature the less the filling grade.
