Product Description

Sika Sikafloor 3240 is a two part solvent free, coloured self-smoothing PUR floor resin, with tough-elastic properties. Sikafloor®-3240 makes use of Sika's unique i-Cure technology to improve surface aesthetics and reduce sensitivity for ambient humidity during application.

Best Uses

Sikafloor®-3240 may only be used by experienced professionals. Sika Sikafloor 3240 is provides a smooth wearing course with crack-bridging properties for industrial floors in production and storage facilities, workshops etc. Also suitable for application as a broadcast wearing course with crack-bridging properties for wet working areas (food and beverage industry etc.), car park decks and loading ramps etc. This product is ideal for  asphalt surfaces, indoor, as in shopping centres, exhibition and storage areas.

  • Flexible and tough-elastic
  • 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


The surface must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. All dust, loose and friable material
must be completely removed from all surfaces before application of the product, preferably by vacuum. Pull of strength shall not be less than 1.5 N/mm2. If in
doubt apply a test area first.

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.

Sikafloor®-3240 must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.

Prior to application, confirm substrate moisture content, relative humidity and dew point. Sikafloor®-3240 is poured and spread evenly by means of a serrated trowel or pin rake. When used in a self smoothing system, roll in two directions with a spike roller to ensure even thickness and to remove entrapped air.

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