Curing Time
Before applying Sikafloor®-359 N on Sikafloor®-375/ -350 N/ -161/ -264 broadcast allow:
| Substrate temperature | Minimum | Maximum | | +10 °C | 24 hours | * | | +20 °C | 12 hours | * | | +30 °C | 6 hours | * |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
* Not applicable as the product will be applied on the structured surface provided by the quartz sand.
