4. Exterior Durability

Resistant to UV exposure, moisture, and temperature fluctuations, making it suitable for terraces and facades.

5. Versatile Application

Compatible with common construction substrates such as concrete, screeds, and cement-based renders.

Application Steps

Surface Preparation

The substrate must be sound, clean, and dry. Dust, oil, loose particles, and contaminants should be completely removed.

Mixing

Mix one 25 kg bag with approximately 6.25 liters of clean water. Allow the mixture to rest for 5 minutes, then remix before application.

Application

Spread the adhesive onto the substrate using a notched trowel. Tiles should be installed before the adhesive surface begins to skin over.

Grouting

Grouting can be carried out after approximately 4–8 hours on walls and 24 hours on floors.

Important Considerations

  • Do not apply in areas exposed to frost or direct intense sunlight.
  • Application temperature should be between +5°C and +35°C.
  • Tile adjustments should be made within approximately 30 minutes after installation.
  • The surface should not be subjected to traffic before complete curing has been achieved.
