RETANOL® XTREME NEATHERM

Retanol® Xtreme NeaTherm

With extremely high early and final strengths (up to CT-C60-F8), Retanol® Xtreme NeaTherm offers a reliable solution for renovation screeds from 25 mm pipe cover or over dimpled sheets and with a total thickness of 30 mm. In addition, the short time required for covering - 2 days for tiles, 3 days for all other coverings and 5 days with underfloor heating - ensures rapid construction progress.

DOSAGE

Compressive strength	CT-C40-F6	CT-C60-F8***
Dosage	400 ml	400 ml
Cement quantity	62,5 kg	75 kg
Commisioning cycle	4 days	4 days

* with underfloor heating/bubble slab
** for ceramic coverings
*** 30–40 %, 2–8 mm gravel to be added

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 gravel.
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.
The specification ‘after x hours’ begins after the last square metre of screed has been laid.
For nominal thicknesses over 80 mm, the readiness for covering may be delayed. Therefore, consult technical support in advance to find a joint solution.

MIXING INSTRUCTIONS

Shake the container well to mix the Retanol® Xtreme NeaTherm additive to a consistent colour before use, and then shake as required throughout the installation to maintain the consistency of the liquid (every 30 mins).
Fill half of mixing vessel with 0-4 mm screeding sand (60-70% fine grains up to 2 mm in diameter, and 30-40% coarse grains greater than 2 mm in diameter).
Add Retanol® Xtreme NeaTherm 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 DIN 1045-2 A/B / BS 13139*, for the production of screed concrete, grit range 0-4 mm
W/C value: Min. 0,4 max. 0,6
Cement: Use of cement according to 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

*UK only

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

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 X®
Density approx. 2,000 to 2,200 kg/m³
Thermal conductivity approx. 2.0-2.4 lambda
Better processing and lower peel resistance
Minimally effected by building climate conditions
Reduction of air content
Start ventilation after 24 hours
80-90 % of final strength 3 days after installation
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 mouisture by PCT Chemie in form 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’ (EU only).
After 56 days, the Retanol® screed is assessed according to the standard values of DIN 18560/BS-8203*.
