Sikafloor®-359 BH

Polyurethane resin

12 months from date of production if stored properly in original, unopened and undamaged sealed packaging

Store in dry conditions in original sealed packaging and at temperatures between +5 °C and +30 °C. Protect from direct sunlight, heat and moisture.

Mixed resin: ~1.33 kg/l (25 °C), may vary with colour

~75 %

~56 %

Short-term moist / wet heat* up to +80 °C where exposure is only occasional (high pressure water jetting etc.)
*No simultaneous chemical and mechanical exposure.

Part A : Part B = 82.5 : 17.5 (by weight)

+10 °C min. / +35 °C max.

80 % r.h. max.

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.

+10 °C min. / +35 °C max.

< 4 % pbw moisture content.
Test method: Sika®-Tramex meter, CM – measurement or oven-dry-method.
No rising moisture according to ASTM (Polyethylene-sheet).

Before applying Sikafloor®-359 BH on basecoats allow waiting time of:

* On fully broadcasted basecoats no maximum waiting time applies. Make sure the fully broadcasted surface is free of dirt, oil, dust or any other contamination.
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity. Refer to PDS of relevant base coat for more information.

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

~0.20–0.3 kg/m²/coat, depending on system, surface profile (roughness), exposure and area of application.

These figures are theoretical and do not include for any additional material required due to surface porosity, surface profile, variations in level and wastage etc..

Sikafloor®-359 BH must be thoroughly mixed using a low speed electric stirrer (300 to 400 rpm) or other suitable equipment.

Mix full kits only. 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.
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.

Prior to application, confirm substrate moisture content, relative humidity and dew point. As a seal coat, the product can be applied by roller or squeegee and then back-rolled (crosswise) with a short-piled roller.

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