Sikafloor®-324

2-PART PUR TOUGH-ELASTIC, LOW-VOC, SELF SMOOTHING FLOOR

Sikafloor®-324 is a two part solvent free, pigmented with FP3 epoxy paste, self smoothing polyurethane resin, with tough-elastic properties. Sikafloor®-324 makes use of Sika's unique i-Cure technology to improve surface aesthetics and reduce sensitivity for ambient humidity during application.

  • Flexible and tough-elastic
  • i-Cure based chemistry
  • Crack-bridging
  • Application on asphalt substrates possible (mastic asphalt)
  • Good chemical and mechanical resistance
  • Solvent-free and low VOC emissions
  • Possible slip resistant surface
  • Easy to apply and to keep clean
  • Economical
  • Not sensitive to moisture

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. When parts A and B have been mixed, add the quartz sand F34 0.1–0.3 mm and mix for a further 2 minutes until a uniform mix has been achieved. To ensure thorough mixing pour the materials into another pail and mix
again to achieve a consistent mix. After mixing leave the mixture for 3 minutes to react before applying.

Mixing Tools
Sikafloor®-324 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®-324 is poured and spread evenly by means of a serrated trowel or pin rake. When used in a selfsmoothing system, roll in two directions with a spike roller to ensure even thickness and to remove entrapped air.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.

CLEANING

To maintain the appearance of the floor after application, Sikafloor®-324 must have all spillages removed immediately and be regularly cleaned using rotary brush, mechanical scrubbers, scrubber dryer, high pressure washer, wash and vacuum techniques etc., using suitable detergents and waxes.
