Application Information Mixing Ratio Part A:Part B = 4:1 (by volume) Ambient Air Temperature +5 °C min. / +40 °C max. Relative Air Humidity 80 % max. Dew Point Beware of condensation.
The substrate and uncured applied coating must be ≥ +3 °C above dew point. Substrate Temperature +5 °C min. / +40 °C max. Substrate Moisture Content The Product can be applied on substrates with a moisture content of ≤ 6 %. The substrate must be visibly dry with no standing water. The following test methods can be used to determine the substrate moisture content: - Sika®-Tramex meter
- CM-measurement
- Oven-dry-method
Waiting Time / Overcoating Before applying SikaRoof® MTC, Sikalastic® or Sikafloor® products on Sika® Bonding Primer, allow: | Substrate temperature | Minimum | Maximum | | +10 °C | 4 hours | 7 days | | +20 °C | 2,5–3,5 hours | 7 days | | +30 °C | 1 hour | 7 days |
Before applying Sikagard® products on Sika® Bonding Primer allow: | Substrate temperature | Minimum | Maximum | | +10 °C | 24 hours | 7 days | | +20 °C | 8 hours | 7 days | | +30 °C | 6 hours | 7 days |
Times are approximate and will be affected by film thickness and changing ambient conditions particularly temperature and relative humidity. |
