Reaction to Fire
Bfl-S1 | (DIN EN 13501-1) |
Chemical Resistance
Resistant to many chemicals. Contact Sika Technical Service for specific information
Thermal Resistance
| Exposure* | Dry heat |
| Permanent | +60 °C |
| Short-term max. 7 days | +80 °C |
| Short-term max. 12 hours | +100 °C |
Short-term moist/wet heat* up to +80 °C where exposure is temporary (i.e. during steam cleaning etc.)
*No simultaneous chemical and mechanical exposure.
Skid / Slip Resistance
| R9 | (DIN 51130) |
Application
Ambient Air Temperature
+10 °C min. / +30 °C max.
Relative Air Humidity
< 75 % maximum. Adequate fresh air ventilation must be provided to remove excess moisture during curing.
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 min. / +30 °C max.
Substrate Moisture Content
≤ 6 % 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
Before applying Sikafloor®-2540 W on Sikafloor®-2540 W allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 48 hours | 7 days |
| +20 °C | 20 hours | 6 days |
| +30 °C | 10 hours | 3 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
If relative air humidity is ≥ 75 % the waiting time is increased by at least 24 hours.
Applied Product Ready for Use
| Temperature | Foot traffic | Light traffic | Full cure |
| +10 °C | ~48 hours | ~5 days | ~10 days |
| +20 °C | ~20 hours | ~3 days | ~7 days |
| +30 °C | ~10 hours | ~ 2 days | ~5 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
