Application
Product Temperature
Maximum | +30 °C |
Minimum | +10 °C |
Ambient Air Temperature
Maximum | +30 °C |
Minimum | +10 °C |
Relative Air Humidity
80 % r.h. max.
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
Maximum | +30 °C |
Minimum | +10 °C |
Substrate Moisture Content
≤ 4% pbw using Sikafloor®-150.
Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method.
No rising moisture according to ASTM (Polyethylene-sheet).
Osmosis caused by rising moisture or incorrect primer application is not covered by the product warranty.
Substrates above 4% but less than 6% pbw maybe primed using Sikafloor®-151,
Please note Sikafloor-151 offers no protection against rising moisture.
Waiting Time / Overcoating
Before applying Sikafloor®-381 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 day |
Note: 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 | ~24 hours | ~3 days | ~10 days |
| +20 °C | ~18 hours | ~2 days | ~7 days |
| +30 °C | ~12 hours | ~1 days | ~5 days |
Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.
Consumption
Sikafloor® MultiDur ES-31 SYSTEM (~2–3 MM)
| Coating System | Product | Consumption |
| Primer | 1 x Sikafloor®-150/-151 | ~0.3–0.5 kg/m² |
| Wearing coat | Sikafloor®- 381 filled with quartz sand 0.1–0.3 mm | 1.8 kg/m2/mm binder + quartz sand +10 °C to +15 °C: without filling +15 °C to +20 °C: 1 : 0.1 pbw (1.65 + 0.15 kg/m²) +20 °C to +30 °C: 1 : 0.2 pbw (1.5 + 0.3 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 product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.
