Application:

1. Mix the Topcem binder with aggregates and water according to the recommended ratio for optimal performance.
2. Ensure the base is clean and free of debris before applying the screed.
3. For underfloor heating applications, install the heating system prior to applying the screed.
4. Allow the screed to set to light foot traffic after 12 hours, and apply flooring as per the recommended waiting times (24 hours for ceramic tiles, 2 days for natural stone, and 4 days for resilient or wood flooring).

Cleaning:

• Clean tools and equipment immediately after use with water to prevent the binder from setting on surfaces.
