ApplicationMixing Ratio Part A : part B = 85 : 15 (by weight) Ambient Air Temperature +10°C (+50 °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. Note: Low temperatures and high humidity conditions increase the probability of blooming. 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 applying Sikafloor®-381 on Sikafloor ® -381 allow:
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity. Applied Product Ready for Use
Note: Times are approximate and will be affected by changing ambient conditions. Consumption
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-31 and Sikafloor® Multidur ES-31 V. MIXING Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 3 minutes until a uniform mix has been achieved. When parts A and B have been mixed, add the quartz sand and if required the Extender T 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®-381 must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment. For the preparation of mortars use a forced action mixer of rotating pan, paddle or trough type. Free fall mixers should not be used. APPLICATION Prior to application, confirm substrate moisture content, relative humidity and dew point. If > 4% pbw moisture content, Sikafloor® EpoCem® should be applied as a T.M.B. (temporary moisture barrier) system. Wearing course (horizontal areas): Sikafloor®-381 is poured, spread evenly by means of a serrated trowel. Roll immediately in two directions with a spiked roller to ensure even thickness. Wearing course (vertical areas): The first layer of Sikafloor®-381, mixed with 2.5 - 4% Extender T, has to be applied by trowel. After curing, apply the second layer of Sikafloor®-381, mixed with 2.5 - 4% Extender T, by trowel. Wearing course with slip resistance: Sikafloor®-381 is poured, spread evenly by means of a serrated trowel and blind the fresh layer with silicon carbide or quartz sand to excess. After final drying the surplus silicon carbide / quartz sand must be swept off and the surface must be vacuumed. The seal coat (Sikafloor®-381 + 5 wt.-% Thinner C) has to be applied evenly by short-piled roller or squeegee. 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. |
