• The specifications refer to a standard mixing vessel with a net capacity of 250 litres
• Fill the screed machine half full with sand and the entire amount of cement.
  • Add Qualimeter 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.

• Grading curve: according to DIN 1045-2 A/B / BS 13139*, 0–8 mm
• W/C value: max. 0,6
• Use of cements according to the PCT cement release list

• Processing +5 °C to +28 °C
• Shake canister every 30 minutes.
• Only use with products from PCT Chemie.
• Do not mix with other screed additives
• Never reactivate screed that has already set with water

• 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.

• 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.

• A Qualimeter screed without an indication of readiness for covering is carried out in accordance with the measurement and assessment standards of DIN 18560/BS 8204*.
• In this case, PCT Chemie and the Retanol® specialist company are not responsible for the readiness for covering.
• The CM measurement is therefore carried out as standard by the floor layer as part of his inspection obligation.
