Curing Time
Before overcoating Sikafloor®-350 N Elastic broadcast allow:
Substrate temperature | Minimum | Maximum |
+10°C | 24 hours | * |
+20°C | 15 hours | * |
+30°C | 8 hours | * |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
* No max. waiting time if fully broadcast surface is free from all contaminations.

Consumption
~ 1.2 kg/m2/mm. Please refer to the respective System Data Sheet
This consumption figures are theoretical and do not include any additional material required due to surface porosity, surface profile, variations in level and wastage etc..
MIXING
Prior to mixing, stir part B mechanically. When all of part A has been added to part B, mix continuously for 2 minutes until a uniform mix has been achieved. 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®-350 N Elastic must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.
APPLICATION
Sikafloor®-350 N Elastic is poured and spread evenly by means of a serrated/notched trowel. Then, level and remove entrained air with a spiked 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.
