Consumption
| Layer | Product | Consumption |
| Primer | Sikafloor®-150 Plus, or Sikafloor®-151 | 1-2 × 0.3–0.5 kg/m² |
| Levelling | Sikafloor®-150 Plus, or Sikafloor®-151, or | Refer to the individual Product Data Sheet. |
| Conductive primer | Sikafloor® Conductive Set Sikafloor®-220 W Conductive | 1 earthing point per 200–300 m², minimum 2 per room. 0.08–0.10 kg/m² |
| Conductive wearing layer | Sikafloor® BC 375 NAS | 1 × 2.0–2.5 kg/m² |
Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply the product to a test area to calculate the exact consumption of the specific substrate conditions and proposed application equipment.
APPLICATION
ESD CONDUCTIVITY MEASUREMENTS
The recommended number of conductivity measurements is specified in the following table:
| Area | Number of measurements |
| < 10 m² | 6 |
| ≥ 10 m² and < 100 m² | 10 to 20 |
| ≥ 100 m² and < 1000 m² | 50 |
| ≥ 1000 m² and < 5000 m² | 100 |
If the measurements yield values that are outside of the agreed specification, follow these steps:
- Carry out one additional measurement within a radius of approximately 30 cm around the original measuring point.
If the value of the new measurement meets the agreed specification, the original measurement can be disregarded. If the value of the new measurement does not meet the agreed specification, repeat the measurement described above until the fulfilment of the requirements have been verified. If the requirements cannot be verified, contact Sika Technical Services.
INSTALLATION OF EARTHING POINTS
Refer to Sika Method Statement: Sika Method Statement — Sikafloor® Mixing and Application.
Number of earthing connections per room: Minimum of 2 earthing connections. The optimum number of earthing connections depends on the local conditions and must be specified on drawings or other contract documentation.
