RETANOL® XR
Retanol® XR
Thanks to its variable dosage system, RetanolXR offers a range of guaranteed drying times from 7 to 21 days. With a compressive and flexural strength of up to C35 N/mm2 and F5 N/mm² respectively, RetanolXR Screed is ideal for parquet flooring and reduced screed thicknesses.

* with underfloor heating
- We recommend for Retanol® screed to add one additional day in regards of drying times.
- 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 screed thicknesses of more than 60 mm, unheated, and 70 mm, heated, always dose with 350 ml.
- For nominal thicknesses over 80 mm, readiness for covering may be delayed. Therefore, consult with technical support find a joint solution.
MIXING INSTRUCTIONS
- Shake the container well to mix the Retanol® 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).
- Fill half of mixing vessel with 0-4 mm screeding sand and required cement
- Add Retanol® to the first mixing water (usually 5-10 litres), then fill the machine completely.
- Gradually add the required amount of residual water until a stiff-plastic consistency is achieved.
- Let the screed mix for a full 2 minutes.
SAND, WATER, CEMENT
- Grading curve: Sand must be according to BS 13139, for the production of screed concrete, grain size range 0-4 mm
- W/C value:Min 0,4, max. 0,6
- Cement: Use of cements according to the PCT cement release list
PROCESSING INSTRUCTIONS
- Working time: 60 minutes
- Finishing time: 90 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
Airing
- If the air humidity is 55 % or higher, ventilate 3-4 times a day for 20-30 minutes 24 hours after screed installation in order to achieve readiness for covering.
- If the humidity is below 55%, contact PCT technical support to avoid cupping etc.
FURTHER PRODUCT FEATURES
- Shrinkage can be further reduced in combination with Agent R®
- Density approx. 2,000 to 2,200 kg/m3
- Thermal conductivity approx. 2.0-2.4 lambda
- Better processing and lower peel resistance
- Minimally affected by building climate conditions
- Reduction of air content
- Start ventilation after 24 hours
- Moisture protection for at least 4 months
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® screed is considered a proprietary screed within its first 56 days after installation , it can not be tested with a RH test, it must be tested with a calcium carbide method before covering.
Can be tested and approved by PCT Chemie in regard of rest moisture by PCT Chemie in form of a CM measurement. - After 56 days, the Retanol® screed is assessed according to the standard values of BS-8203.
