Application
Mixing Ratio
Part A : part B = 64 : 36 (by weight)
Ambient Air Temperature
+10 °C min. / +30 °C max
Relative Air Humidity

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
≤ 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
| Temperature | Time |
| + 10 °C | ~50 minutes |
| + 20 °C | ~25 minutes |
| + 30 °C | ~15 minutes |
Curing Time
Waiting Time / Overcoating
Before applying Sikafloor®-160 HC on Sikafloor®-160 HC allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 24 hours | 4 days |
| +20 °C | 12 hours | 2 days |
| +30 °C | 6 hours | 1 day |
Before applying solvent containing products on Sikafloor®-160 HC allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 30 hours | 3 days |
| +20 °C | 20 hours | 2 days |
| +30 °C | 10 hours | 1 day |
Notes : Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

Consumption
| Coating System | Product | Consumption |
| Priming | Sikafloor®-160 HC | 0.35 - 0.55 kg/m2 |
| Levelling mortar fine (surface roughness < 1 mm) | 1 pbw Sikafloor®-160 HC + 0.5 pbw quartz sand (0.1 - 0.3 mm) + 0.015 pbw Extender T | 1.7 kg/m2/mm |
| Levelling mortar medium (surface roughness up to 2 mm) | 1 pbw Sikafloor®-160 HC + 1 pbw quartz sand (0.1 - 0.3 mm) + 0.015 pbw Extender T | 1.9 kg/m2/mm |
Note: These figures are theoretical and do not allow for any additional material required due to surface porosity, surface profile, variations in level or 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, if required add the quartz sand and or the Extender T 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®-160 HC 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, r.h. and dew point.
If > 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®-160 HC by brush, roller or squeegee.
Levelling mortar
Rough surfaces need to be levelled first. Apply the levelling mortar by squeegee/trowel to the required thickness.
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.
