Part A 13.09 kg containers
Part B   4.0   kg containers
Part A+B 17.09 kg ready to mix units

Mixing ratio

Part A : part B = 77 : 23 (by weight) – 2.1 : 1 (by volume)


Ambient air temperature

+10 °C min. / +30 °C max.


Relative air humidity

80 % r.h. max.


Dew point

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.

Note: Low temperatures and high humidity conditions increase the probability of blooming.


Substrate temperature

+10°C min. / +30°C max.


Substrate moisture content

Maximum 6 % moisture content using the Sika® – Tramex meter (at the time of application).
Please note that the moisture content must be < 6 % pbw when using the CM measurement or Oven-dry-method.

No rising moisture according to ASTM (Polyethylene-sheet).


Pot Life

Temperature Time
+10 °C ~ 50 minutes
+20 °C ~ 25 minutes
+30 °C ~ 15 minutes


Curing time

Before applying solvent free products on Sikafloor®-161 allow:

Substrate temperature Minimum Maximum
+10 °C 24 hours 4 days
+20 °C 12 hours 2 days
+30 °C 8 hours 24 hours

Before applying solvent containing products on Sikafloor®-161 allow:

Substrate temperature Minimum Maximum
+10 °C 36 hours 6 days
+20 °C 24 hours 4 days
+30 °C 16 hours 2 days

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

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.

Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
