ApplicationMixing Ratio Part A : Part B = 81 : 19 (by weight) Ambient Air Temperature +10 °C (+50 °F) min. / +30 °C (+86 °F) max. Relative Air Humidity ~75 - 80 % Dew Point Beware of condensation! The substrate and uncured floor must be at least 3 °C (37 °F) above dew point to reduce the risk of condensation or blooming on the floor finish. Substrate Temperature +10 °C (+50 °F) min. / +30 °C (+86 °F) 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
Curing Time Before overcoating Sikafloor®-3240 allow:
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
Note: Times are approximate and will be affected by changing ambient conditions. Consumption Please refer to the System Data Sheets 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. If quartz sand addition to the mix is requied (according to the system), you can add it only when parts A and B have been mixed. Add the quartz sand F34 0.1 – 0.3 mm (0.0039 – 0.0118 in) and mix for 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®-3240 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®-3240 (with quartz sand addition) 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. Sikafloor®-3240 (without quartz sand addition) can be applied by brush, roller or squeegee. 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®-3240 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. |
