Ambient Air Temperature
+10 °C min. / +30 °C max.
Relative Air Humidity
75% r.h. max.
Dew Point
Beware of condensation!
The substrate and uncured floor coating must be at least 3°C above dew point to reduce the risk of condensation or blooming on the floor finish.
Substrate Temperature

Substrate Moisture Content
< 6% pbw moisture content.
Test method: Sika-Tramex meter or CM-measurement.
No rising moisture according to ASTM (Polyethylene-sheet).
Pot Life
| Substrate temperature | Time |
| +10 °C | ~120 min |
| +20 °C | ~90 min |
| +30 °C | ~30 min |
Curing Time
Before applying Sikagard® WallCoat ID on Sikagard® WallCoat ID + 5% water allow:
| Substrate temperature | Min. waiting time | Max. waiting time |
| +10 °C | 48 hours | 7 days |
| +20 °C | 15 hours | 5 days |
| +30 °C | 10 hours | 3 days |
Before applying Sikagard® WallCoat ID on Sikagard® WallCoat ID allow:
| Substrate temperature | Min. waiting time | Max. waiting time |
| +10 °C | 24 hours | 7 days |
| +20 °C | 12 hours | 5 days |
| +30 °C | 10 hours | 3 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

Note: Times are approximate and will be affected by changing ambient conditions
Consumption
| Coating System | Product | Consumption |
| Priming | Sikagard® WallCoat ID + 5% water | ~140 g/m2 |
| Coat | 2 - 3 x Sikagard® WallCoat ID | 100 - 150 g/m2 per coat |
These figures are theoretical and do not include for any additional material required due to surface porosity, surface colour, 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 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 minimize air entrainment
MIXING TOOLS
Sikagard® WallCoat ID must be mechanically mixed using an electric power stirrer (300 - 400 rpm) or other suitable equipment.
APPLICATION
Prior to application, confirm substrate moisture content, relative humidity and dew point.
If > 6% pbw moisture content, Sikagard®-720 EpoCem® HC may be applied as a T.M.B. (temporary moisture barrier) system.
Primer
Make sure that a continuous, pore free coat covers the substrate. Apply the Sikagard® WallCoat ID + 5% water by brush or roller.
Wall coating
Apply Sikagard® WallCoat ID by roller.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
