2-component, epoxy repair, filling, sealing and forming mortar Sika Repair-EP is a thixotropic, two-component, repair, filling, sealing and forming mortar, based on a combination of epoxy resins with refined quartz fillers. - Fast cure.
- Suitable for dry and damp concrete surfaces.
- Non-shrink curing.
- Curing is not hindered by high humidity.
- Excellent adhesion to concrete.
- High mechanical resistance.
- Resistant to impact and abrasion.
- Thixotropic, non-sagging.
- Vertical and overhead applications possible.
- Different coloured components (for mixing control).

Application Information Mixing Ratio Component A : Component B = 97.12 : 2.88 (parts by weight). Layer Thickness Horizontal: 60mm maximum. Vertical: 25mm maximum. Overhead: 10mm maximum. Product Temperature Minimum +5°C, Maximum +30°C. Ambient Air Temperature Minimum +5°C, Maximum +30°C. Dew Point Beware of condensation! The ambient temperature during application must be at least 3°C higher than the dew point. Substrate Temperature Minimum +5°C, Maximum +30°C. Pot Life Approximately 90 minutes at +20°C. The pot life starts when the resin and hardener are added, then mixed. It is shorter at high temperatures and longer at low temperatures. With a larger compact amount of mixed material, processing time will be shortened. In order to lengthen the application time at high temperatures, the amount to be mixed can be part mixed in line with the ratio and by weight. Another method is to cool components A + B before mixing (not below +5ºC). Waiting Time / Overcoating | Temperature | Cured | Fully Polymerized | | +5°C +5°C+5°C | ~36 hours | 21 days | | +20°C | ~12 hours | 14 days | | +30°C | ~6 hours | 6 days |
Note: Times are approximate and will be affected by changes in ambient temperatures and environmental conditions. |
