Mixing ratio
| Part A : Part B (by weight) | 84 : 16 (by weight) |
Product temperature
| Maximum | +30 °C |
| Minimum | +10 °C |
Ambient air temperature
| Maximum | +30 °C |
| Minimum | +10 °C |
Relative air humidity
80 % r.h. max.
Dew point
Beware of condensation. The substrate and uncured applied product must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product. Low temperatures and high humidity conditions increase the probability of blooming.
Substrate temperature
| Maximum | +30 °C |
| Minimum | +10 °C |
Substrate moisture content
| Substrate | Method | Moisture content |
| Cementitious substrates | Sika® Tramex moisture metre | ≤ 6 % |
| Cementitious substrates | Calcium carbide method (CM-method) | ≤ 4 % |
No rising moisture (ASTM D4263, polyethylene sheet)
IMPORTANT
Temporary moisture barrier
If the substrate moisture content measured with the CM-method is > 4% by weight, apply a temporary moisture barrier consisting of Sikafloor® EpoCem®.
