Curing Time
Before applying Sikafloor®-359 N on Sikafloor®-375/ -350 N/ -326/ -261 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.

MIXING
Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 2 minutes until a uniform mix has been achieved.
For the addition of quartz sand: When parts A and B have been mixed, add the quartz sand 0.1 - 0.3 mm and mix for a further 2 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over mixing must be avoided to minimise air entrainment.
Mixing Tools:
Sikafloor®-359 N must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.
APPLICATION
Prior to application, confirm substrate moisture content, relative humidity and dew point. As a seal coat, the product can be applied by squeegee and then back-rolled (crosswise) with a short-piled roller.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
