Before applying Sikafloor®-359 N on Sikafloor®-375/ -350 N/ -326/ -261  broadcast allow:

Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

* Not applicable as the product will be applied on the structured surface provided by the quartz sand.

Note: Times are approximate and will be affected by changing ambient conditions

~0.7–0.9 kg/m²/layer. Please refer to the respective System Data Sheet.

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.
 

For the addition of quartz sand: When parts A and B have been mixed, add the quartz sand 0.1 - 0.3 mm 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®-359 N 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. As a seal coat, the product can be applied by squeegee and then back-rolled (crosswise) with a short-piled roller.

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