Available in RAL 1014, RAL 2000, RAL 3009, RAL 5015, RAL 6010, RAL 7042, RAL 8002, RAL 9001, RAL 9005.
The colour of the Sikafloor®-3310 has to be approximately adjusted to the colour of the Sikafloor®-305 W seal / top coat.
Applied colours selected from colour charts will be approximate. For colour matching: Apply colour sample and confirm selected colour under real lighting conditions.
When product is exposed to direct sunlight, there may be some discolouration and colour variation, this has no influence on the function and performance of the floor finish.

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.

Application steps

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®-3310 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®-3310 is poured and spread evenly by means of a serrated trowel or pin rake. Once Sikafloor®-3310 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.
Please refer to the Sika® Method Statement Mixing & Application.
