Retanol® Xtreme

The high-performance screed is characterised by its extremely high early and final strengths as well as short readiness for covering. Retanol® Xtreme enables a readiness for covering of 2 days for tiles, 3 days for all other coverings and 5 days with underfloor heating. In addition, Retanol® Xtreme achieves 80-90 % of its final strength within 72 hours - up to CT-C60-F8.

Dosage400 ml400 ml
Cement quantity62,5 kg75 kg
Commisioning cycle4 days4 days

* with underfloor heating
** for ceramic coverings

  • Do not exceed the maximum dosage of 500 ml.
  • The specifications refer to a standard mixing vessel with a net capacity of 200 litres and a filling quantity of approx. 320 kg screed sand.
  • The strength class depends on the quality of the screed sand used.
  • The specification ‘after the X. Day’ does not include the day of installation.
  • For nominal thicknesses over 80 mm, readiness for covering may be delayed. Therefore, consult with technical support find a joint solution.
  • Applies to all product versions: Xtreme/Xtreme Pro 1/Xtreme Pro 2 

MIXING INSTRUCTIONS

  1. Shake the container well to mix the Retanol® Xtreme additive to a consistent colour before use, and then shake as required throughout the installation to maintain the consistency of the liquid (every 30 min).
  2. Fill half of mixing vessel with 0-4 mm screeding sand and required cement.
  3. Add Retanol® Xtreme to the first mixing water (usually 5-10 litres), then fill the machine completely.
  4. Gradually add the required amount of residual water until a stiff-plastic consistency is achieved.
  5. Let the screed mix for a full 2 minutes.

SAND, WATER, CEMENT

  • Grading curve: Sand must be according to DIN 1045-2 A/B, for the production of screed concrete, grain size range 0-8 mm
  • W/C value: Max. 0,6
  • Cement: Use of cement according to the PCT cement release list
  • ≥ C60-F8 and/or ready for covering after the 2nd day for tiles: 75 kg cement grade 42.5 R/N

PROCESSING INSTRUCTIONS

  • Working time: 45 minutes
  • Finishing time: 60 minutes
  • Outside temperature: +5 °C to +28 °C for screed, environment and substrate
  • Do not mix with other screed additives
  • Never reactivate screed that has already set with water

Protective instructions during and after installation

  • We recommend our PROTEC-ES/SP product to protect against drying out too quickly, depending on the floor covering. We recommend consulting the PCT technical support team.
  • Protect the screed against rapid drying of the surface due to draughts, sunlight and low humidity.
  • Large window fronts and floor-level glass façade areas should be darkened if necessary.
  • Cover screeds in outdoor areas or enclose areas to be covered. Contact PCT technical support if screed is to be laid outdoors.

CM MEASUREMENT

  • A Retanol® Xtreme screed is considered a special screed in terms of readiness for covering in the first 56 days after installation and can be tested and approved by PCT Chemie with regard to its readiness for covering by means of a CM measurement.
  • The CM measurement, including the issuing of a guarantee declaration and the assumption of the warranty, can be ordered free of charge from PCT Chemie during this period by the Retanol® specialist company, floor layers, tilers or the client. Further information on the release of the screed can be found on our homepage under ‘Guarantee’.
  • After 56 days, the Retanol® screed is assessed in accordance with the standard values of DIN 18560.
