Considering the installation of underfloor heating in your residential or commercial property? A common query relates to the duration you must wait before you can activate the system following the application of screed. While the specific waiting period can vary based on several factors, a general guideline is to allow at least seven days before turning on your underfloor heating.
Understanding Screed and Its Importance
Screed is essentially a mix of cement and sand applied thinly to create a level and smooth surface over a concrete subfloor, serving as a base for the final flooring. The screed thickness typically ranges from 50 to 75 millimeters, tailored to support the installation of underfloor heating systems.
The Crucial Waiting Period
The key reason for the waiting period is to allow the screed sufficient time to dry and cure properly. This phase is critical as it involves the evaporation of moisture from the screed. Activating the underfloor heating too soon could lead to potential damage due to the presence of excessive moisture.
Factors Influencing Drying Time
- Screed Thickness: Thicker screed layers naturally require a longer drying time than thinner ones.
- Environmental Conditions: The room’s temperature and humidity levels can accelerate or slow down the drying process.
- Screed Type: Different screed materials have varying drying times, with some needing longer than others to fully cure.
It’s generally advisable to follow the manufacturer’s recommended drying time, which could vary from seven to twenty-eight days, depending on the specific screed used.
Safely Activating Underfloor Heating
Once the screed has adequately dried and cured, you can proceed to activate the underfloor heating. However, it’s essential to gradually increase the temperature, not exceeding a 5°C increase per day, to reach the desired setting. This precaution helps prevent any damage to both the screed and the heating system.
Conclusion
A minimum wait of seven days is recommended before activating underfloor heating after screeding, ensuring the screed is thoroughly dried and avoiding any damage. Adhering to the screed manufacturer’s drying time and gradually increasing the heating system’s temperature are key steps to ensure the longevity and effectiveness of your underfloor heating.
