Heating protocol for ceramic coverings on ‘green’ cementbased and calcium sulphate screeds with SANIFIN-EKB Client: Building / property: Building section / part / storey / apartment: Building part: REQUIREMENTS Before starting installation work, the cement-based or calcium sulphate screed must be checked for quality, final screed thickness, suitability, load-bearing capacity and age. Furthermore, the moisture content must be determined using the CM method. The information in the technical data sheet for SANIFIN-EKB must be observed. REQUIREMENTS for ‘green’ calcium sulphate screeds Before starting installation work on a ‘green’ calcium sulphate screeds, residual moisture content must be determined using the CM method. The residual moisture content may not exceed 1.2 CM-%. The calcium sulphate screeds must be prepared with the primer ASO-Unigrund-PLUS and tiles laid with tile adhesive MONOFLEX-S2. Documentation 1. Nature of screed (if applicable manufacturer): Binder used: days Defined setting times: 2. End of the screed work: Date 3. Start of functional heating: Date - 28 days after completion of the tiling work at the earliest - Start of functional heating with a flow temperature of +20°C for 3 days at a constant flow temperature (without night setback and/or interruption): Date up to , max. flow temperature
°C
4. Raising the flow temperature to +25°C from day 4 to day 7 of functional heating (without night setback and/or interruption): Date up to , max. flow temperature
5. Raising the flow temperature to +35°C from day 7 to day 10 of functional heating (without night setback and/or interruption): Date up to , max. flow temperature
6. Lowering the flow temperature to +20°C from day 10 to day 11 of functional heating (without night setback and/or interruption): Date up to , max. flow temperature
7. Transition to control mode with a maximum flow temperature of +30°C for subsequent use from day 12 of functional heating. Date , max. flow temperature °C Was the functional heating interrupted? Yes If yes: from date until

Heating protocol for ceramic coverings on ‘green’ cementbased and calcium sulphate screeds with SANIFIN-EKB NOTE Depending on the heat output of the heat generator, functional heating may need to be carried out in sections. However, all heating circuits within a screed field must be heated simultaneously. When switching the floor heating system off and on during the construction phase and later use, the floor construction must be protected from cooling down and heating up too quickly.
