1 In accordance with IEC 61340-5-1 and ANSI/ESD S20.20.
2 Readings may vary, depending on ambient conditions (i.e. temperature, humidity) and measurement equipment.
Application
Material temperature
+10 °C min. / +30 °C max.
Ambient air temperature
+10 °C min. / +30 °C max.
Relative air humidity
80 % max
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 floor finish.
Substrate temperature
+10 °C min. / +30 °C max.
Substrate moisture content
Sikafloor® MultiFlex PS-32 ESD can be installed on substrates with a moisture content of ≤ 4 % (checked by Tramex) with no rising moisture. The substrate needs to be visibly dry and have a minimum tensile strength of 1,5 N/mm2.
Waiting time to overcoating
Before applying Sikafloor®-3240 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®-3240 allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 24 hours | 72 hours |
| +20 °C | 12 hours | 48 hours |
| +30 °C | 8 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
| Layer | Product | Consumption |
| 1. Primer | Sikafloor®-160/-161 | 1–2 × ~0,3–0,5 kg/m² |
| 2. Levelling (if required) | Sikafloor®-160/-161 levelling mortar | Refer to PDS of Sikafloor®-160/-161 |
| 3. Base coat | Sikafloor®-377 Tinted | ~1,8 kg/m2/layer (~1 mm thickness) |
| 4. Earthing connection | Sika® Earthing Kit | 1 earthing point per approx. 200–300 m2, min. 2 per room. |
| 5. Final conductive coating | Sikafloor®-305 W ESD | 1–2 × 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 of Sikafloor®-305 W ESD improves the mechanical properties of the final coating.
Lower consumption can cause roller marks, gloss differences and irregular surface structure. Higher consumption results in water retention and can cause pigment floatation as well as unsatisfactory conductivity.
