| Sikafloor-3240 is a two-part solvent free, coloured self-smoothing PUR resin, total solid according to Deutsche Bauchemie, 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. - 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
|
Usage - Smooth wearing course with crack-bridging properties for industrial floors in production and storage facilities, workshops, etc.
- Broadcast wearing course with crack-bridging properties for wet working areas (food and beverage industry etc.), car park decks and loading ramps, etc.
- Applicable on asphalt surfaces, indoor, as in shopping centres, exhibition and storage areas.

Application Information Mixing Ratio Part A : Part B = 81 : 19 (by weight) Ambient Air Temperature +10 °C min. / +30 °C max. Relative Air Humidity ~ 75 - 80 % Dew Point Beware of condensation!
The substrate and uncured floor must be at least 3 °C above dew point to reduce the risk of condensation or blooming on the floor finish. Substrate Temperature +10 °C min. / +30 °C max. Substrate Moisture Content < 4 % pbw moisture content.
Test method: Sika-Tramex meter, CM - measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet). Pot Life | Temperatures | Time | | +10 °C | ~ 40 minutes | | +20 °C | ~ 30 minutes | | +30 °C | ~ 20 minutes |
Curing Time Before overcoating Sikafloor-3240 allow: | Substrate temperature | Minimum | Maximum | | +10 °C | ~ 30 hours | ~ 72 hours | | +20 °C | ~ 24 hours | ~ 48 hours | | +30 °C | ~ 16 hours | ~ 36 hours |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity. If maximum waiting time is exceeded, the Sikafloor-3240 surface have to be grinded to get mechanical bonding between the Sikafloor layers Applied Product Ready for Use | Temperature | Foot traffic | Light traffic | Full Cure | | +10 °C | 1 day | 3 days | 9 days | | +20 °C | 12 hours | 2 days | 5 days | | +30 °C | 8 hours | 1 day | 3 days |
Note: Times are approximate and will be affected by changing ambient conditions |
