Application

Application Information

Mixing Ratio

Part A : Part B = 85 : 15 (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

Be aware 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.

Application steps

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®-306 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®-306 W by using a short pile nylon roller. Sikafloor®-306 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.

CLEANING

Please refer to “Sikafloor®- CLEANING REGIME”.
