TECHNICAL INFORMATION

• Shore D Hardness: ~70 (at +25°C) (DIN 53 505)
• Tensile Adhesion Strength: >1.5 N/mm² (after 28 days, failure in concrete) (ASTM D4541)

APPLICATION INFORMATION

• Mixing Ratio: Part A : Part B = 83.33 : 16.67 (by weight)
• Consumption:
  • 1 – 2 coats at 0.3 – 0.5 kg/m²
  • Consumption may vary depending on the system, exposure, and area of application. The theoretical value does not account for additional material due to surface porosity, profile variations, and wastage.
• Ambient Air Temperature: +10°C min. / +35°C max.
• Relative Air Humidity: Max. 80%
• Dew Point: Ensure the substrate and uncured floor are at least 3°C above the dew point to prevent condensation or blooming. Low temperatures and high humidity can increase the risk of blooming.
• Substrate Temperature: +10°C min. / +35°C max.
• Substrate Moisture Content: <4% by weight, measured with the Sika®-Tramex meter, CM measurement, or oven-dry method. Ensure no rising moisture according to ASTM (Polyethylene-sheet).
• Pot Life: ~50 minutes at +25°C

Waiting Time for Overcoating

• Substrate Temperature:
  • At +10°C: Minimum 24 hours, Maximum 4 days
  • At +20°C: Minimum 12 hours, Maximum 2 days
  • At +30°C: Minimum 8 hours, Maximum 24 hours

These times are approximate and may vary depending on ambient conditions such as temperature and relative humidity.
