Application

Used for interior applications to level out the following:

  • Uneven cement-based substrates.
  • Old ceramic floors.

Must be used in its original state, without the addition of other materials. Highly absorbent surfaces must be treated beforehand.

Drying time is dependent on thickness, the water content of the mix and the thermo-hygrometric conditions. Consult manufacturer's literature for details on recommended substrate preparation and mixing instructions.

Description

Dry, pre-mixed, quick-drying and self-levelling cement floor screed. Composed of hydraulic binders, and selected sands and additives. To be applied in thicknesses of between 3–30 mm.

Features and benefits:

  • Rapid hydration and setting.
  • Improved workability and self-levelling properties.
  • Suitable for use when a fast drying time is necessary to allow the floor covering to be laid quickly.
  • Applicable by hand or machine.
  • Contributes to LEED® credits.
  • CE marked, and manufactured in accordance with EN 13813.
