Chemical Base
PUR
Shelf Life
6 months from date of production
Storage Conditions
The product must be stored properly in original, unopened and undamaged sealed packaging, in dry conditions at temperatures between +5 °C and +30 °C.
Prolonged vibrations and higher ambient temperatures during transportation can result in settling of component A, which makes mixing more difficult. Prolonged storage at low temperatures can result in crystallizing of component B.

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. 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®-330 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.
Sikafloor®-330 is poured and spread evenly by means of a serrated trowel or pin rake. Once Sikafloor®-330 is “tack-free” apply the seal coat.
CLEANING OF TOOLS
Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
