Application
Mixing Ratio
Part A : Part B = 4.71 : 1 (by weight)
Ambient Air Temperature
+10 °C min. / +35 °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. / +35 °C max.
Substrate Moisture Content
< 4 % pbw moisture content using the Sika® - Tramex meter (at the time of application).
Pot Life
| Temperature | Time |
| +10 °C | ~60 min |
| +20 °C | ~30 min |
| +30 °C | ~15 min |
Curing Time
Before applying solvent free products on Sikafloor®-161 G allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 24 h | 4 d |
| +20 °C | 12 h | 2 d |
| +30 °C | 8 h | 24 h |
Before applying solvent containing products on Sikafloor®-161 G allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 36 h | 6 d |
| +20 °C | 24 h | 4 d |
| +30 °C | 16 h | 2 d |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Consumption
| Coating System | Product | Consumption |
| Priming | 1 - 2 x Sikafloor®-161 G | 1 - 2 x 0.25 - 0.55 kg/m² |
| Levelling mortar fine (surface roughness < 1 mm) | 1 pbw Sikafloor®-161 G + 0.5 pbw quartz sand (0.1 - 0.3 mm) | ~1.7 kg/m²/mm |
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.
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®-161 G 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 more than 4 % pbw moisture content, Sikafloor® EpoCem® may be applied as a T.M.B. (temporary moisture barrier) system.
Primer
Make sure that a continuous, pore free coat covers the substrate. If necessary, apply two priming coats. Apply Sikafloor®-161 G by brush, roller or squeegee. Preferred application is by using a squeegee and then back rolling crosswise.
Bonding bridge
Apply Sikafloor®-161 G by brush, roller or squeegee. Preferred application is by using a squeegee and then backrolling crosswise.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
