Application steps

SUBSTRATE QUALITY

Substrate must be sound, free from oil, grease, loose and friable particles.
Slightly damp substrates are acceptable. Standing water must be removed (e.g. by vacuum extraction or oil free compressed air) before pouring Sika® Icosit® KC 330 FK NEW.

SUBSTRATE PREPARATION

To improve adhesion, apply Sika® Icosit® KC 330 Primer as a primer on absorbent substrates (concrete).

MIXING

Sika® Icosit® KC 330 FK NEW  is supplied in pre-weighed composite units consisting of parts A + B.

 

Part A must be stirred thoroughly before being mixed with part B.

The following mixing instructions must be carried out:

  • Use an electric or pneumatic mixer with basket type stirrer (diameter 120–140 mm, speed ~600–800 rpm).
  • Mixing time ~60 to 80 seconds.
  • Ensure material is mixed from the container walls and the base by the stirrer during mixing.

During mixing until approximately 3 minutes afterwards, material remains liquid (pourable) and subsequently turns into a thixotropic, sag-resistant, trowel-applicable consistency.

CLEANING OF TOOLS

Mixing and application tools must be cleaned at regular intervals and immediately after use with Sika® Thinner C. Hardened material can only be removed mechanically.
