Application
Mixing Ratio
Part A : part B = 80 : 20 (by weight)
Ambient Air Temperature
+10°C min. / +30°C max.
Relative Air Humidity
75% max.
During curing the humidity should not exceed 75 % max. Adequate fresh air ventilation must be provided to remove the excess moisture from the curing product.
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
+10°C min. / +30°C max.
Pot Life
Temperatures | Time |
+10°C | ~ 50 minutes |
+20°C | ~ 30 minutes |
+30°C | ~ 20 minutes |
Caution: End of pot life is not noticeable.
Curing Time
Before overcoating Sikafloor®-304 W
Substrate temperature | Minimum | Maximum |
+10°C | 26 hours | 4 days |
+20°C | 16 hours | 3 days |
+30°C | 12 hours | 2 days |
Based on relative humidity of max. 70 % and good ventilation. 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 | ~ 30 hours | ~ 48 hours | ~ 6 days |
+20°C | ~ 16 hours | ~ 24 hours | ~ 4 days |
+30°C | ~ 12 hours | ~ 18 hours | ~ 3 days |

MIXING
Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 3 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.
After mixing give the material a rest for 10 minutes.
Over mixing must be avoided to minimise air entrainment.
Mixing Tools:
Sikafloor®-304 W 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. Uniformly spread Sikafloor®-304 W by using a short pile nylon roller. Sikafloor®-304 W can also be applied by using a airless spray equipment. A seamless finish can be achieved if a “wet” edge is maintained during application.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use.
Hardened and/or cured material can only be removed mechanically.
