Application
Ambient Air Temperature
Maximum | +30 °C |
Minimum | +10 °C |
Relative Air Humidity
Maximum | 80 % r.h. |
Dew Point
Beware of condensation. The substrate and uncured applied product must be at least +3 °C above the dew point to reduce the risk of condensation or blooming on the surface of the applied product. Low temperatures and high humidity conditions increase the probability of blooming.
Substrate Temperature
Maximum | +30 °C |
Minimum | +10 °C |
Substrate Moisture Content
Refer to the individual Product Data 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®-381 on the primer allow:
Temperature | Minimum | Maximum |
+10 °C | 17 hours | 4 days |
+20 °C | 9 hours | 2 days |
+30 °C | 7 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
Layer | Product | Consumption |
Primer | Sikafloor®-150 Sikafloor®-151 Sikafloor®-156 Sikafloor®-161 Sikafloor®-1590 | 1–2 × 0.3–0.5 kg/m² |
Wearing layer | Sikafloor®-381 filled with Quartz sand (0.1–0.3 mm) | 1.8 kg/m2 per mm binder + quartz sand +10 °C to +15 °C: without filling +15 °C to +20 °C: 1 : 0.1 by weight (1.65 + 0.15 kg/m²) +20 °C to +30 °C: 1 : 0.2 by weight (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 the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.
