- Easy workability
- Highly thixotropic: Keraflex Extra S1 can be applied on a vertical surface without sagging and without the risk of tiles sliding; Therefore, these can be installed from the top down without the need for cross braces.
- Good capacity to absorb differential deformations between the coating and the support

Gluing ceramic tiles (double-fired, single-fired, porcelain, clinker, etc.) and stone (as long as they are not sensitive to humidity) on conventional supports that may suffer deformations, such as:
- Cement screeds, even with underfloor heating installations
- Anhydrite screeds, previously treated with a Primer G or Eco Prim T primer
- Cement plasters, or lime and cement mortar
- Single-layer plaster plasters
- Drywall, as long as it is securely fastened
