ApplicationMixing Ratio Part A : part B = 83 : 17 (by weight) Ambient Air Temperature +15 °C (+59 °F) min. / +30 °C (+86 °F) max. Relative Air Humidity 80 % r.h. max. 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 +15 °C (+59 °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®-269 CR allow:
Consumption ~ 1.8—2.0 kg/m² applied as a self-smoothing wearing course These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc. For detailed info, please refer to the System data sheet Sikafloor® MultiDur ES-28 EQ. 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 0.1 - 0.3 mm (0.0039 - 0.0118 in) and mix for a further 2 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over mixing must be avoided to minimise air entrainment. Mixing Tools Sikafloor®-269 CR 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 air humidity and dew point. If > 4% pbw moisture content, Sikafloor® EpoCem® may be applied as a temporary moisture barrier (T.M.B.) system. Levelling: Rough surfaces need to be levelled first. Therefore use Sikafloor®-144 /-161/ -701 levelling mortar (see PDS). Wearing course smooth: Sikafloor®-269 CR is poured, spread evenly by means of a serrated trowel. After spreading the material evenly, turn the serrated trowel and smooth the surface in order to achieve an aesthetically higher grade of finish. Roll immediately (within max. 10 minutes of application) in two directions with a steel spiked roller to ensure even thickness and to remove entrapped air. To obtain the highest level of aesthetic finish, spike roll in two directions at a 90 degree angle, passing only once in each direction. CLEANING OF TOOLS Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically. |
