Electrostatic Behaviour
ESD MEASUREMENT CONDITIONS AND SPECIFICATIONS All measurement values for the System stated in the System Data Sheet (except those referring to proof statements) were measured using the following equipment and ambient conditions:
IMPORTANT ESD footwear requirements The ESD shoes used in the EPA must have a resistance of < 5 MOhm according to IEC 61340-4-3 at climate class 1 (12 % relative humidity and +23 °C). In order to achieve charges of < 30 volts of human body charge during the walking test (at 12 % relative humidity and +23 °C), we recommend using the following ESD shoes: Weeger ESD clog, art. 48512-30 (www.schuh-weeger.de). NOTE: Measurement results can be affected by ESD clothing, ambient conditions, measurement equipment, cleanliness of the floor and the test personnel. |
Application
Product Temperature
+10 °C minimum / +30 °C maximum
Ambient Air Temperature
+10 °C minimum / +30 °C maximum
Relative Air Humidity
During curing the humidity must not exceed 75 %. There must be a sufficient supply of fresh air or a dehumidifier to remove excess moisture from cured water based products.
Dew Point
Beware of condensation. The substrate and uncured applied floor material must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product.
Substrate Temperature
+10 °C minimum / +30 °C maximum
Substrate Moisture Content
≤ 4 % parts by weight. The following test methods can be used: Sika®-Tramex meter, CM-measurement or oven-dry-method. No rising moisture according to ASTM (polyethylene-sheet).
Waiting Time / Overcoating
When using Sikafloor®-1590, refer to the individual Product Data Sheet for specific information on waiting time to overcoating.
Before applying Sikafloor®-263 SL N /-264 N on Sikafloor®-150/-151 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®-263 SL N /-264 N allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 36 hours | 7 days |
| +20 °C | 24 hours | 5 days |
| +30 °C | 16 hours | 3 days |
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 |
| +20 °C | ~24 hours | ~3 days | ~8 days |
| +30 °C | ~16 hours | ~2 days | ~7 days |
NOTE: Times apply when the last layer of the System has been applied. Times are affected by changing ambient conditions, particularly temperature and relative humidity.
Consumption
| Layer | Product | Consumption |
| 1. Primer | Sikafloor®-150/-151/1590 | 1 to 2 × ~ 0,3 to 0,5 kg/m² |
| 2. Levelling (if required) | Sikafloor®-150/-151 levelling mortar | Refer to PDS of Sikafloor®-150/-151 |
| 3. Base Coat | Sikafloor®-263 SL N /-264 N filled with quartz sand F34 | ~1,9 to 2,7 kg/m² Binder + quartz sand F 34: 1:0,6 to 1:1 pbw (depending on the air temperature the filling grade varies) |
| 4. Earthing Connection | Sika® Earthing Kit | 1 earthing point per ~200 to 300 m². 2 per room minimum |
| 5. ESD Coating | Sikafloor®-305 W ESD | 1 to 2 × 0,18 to 0,2 kg/m²/layer |
NOTE: These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage, etc.
NOTE: When used in high wear conditions (e.g. with castor chairs), a second layer of Sikafloor®-305 W ESD improves the mechanical properties of the final coating.
APPLICATION
The number of conductivity measurements is recommended in the table below:
| Ready Applied Area | Number of Measurements |
| <10 m2 | 6 measurements |
| <100 m2 | 10 to 20 measurements |
| <1000 m2 | 50 measurements |
| < 5000 m2 | 100 measurements |
NOTE: If values are lower / higher than required, additional measurements must be carried out, ~30 cm around the point where the faulty readings are located. If the re-measured values are in accordance with the requirements, the total area is acceptable.
NOTE: Installation of earthing points: Refer to Sika® Method Statement: Mixing and Applications of Flooring Systems.
NOTE: Numbers of earth connections per room: Minimum of 2 earthing points. The optimum number of earth connections depends on the local conditions and must be specified on available drawings or other contract documentation.
CLEANING
