Screed is a material generally used for ground leveling in construction projects. Correct drying of the screed is important for its durability and performance. However, complete drying time may vary depending on several factors.

Factors affecting the drying time of the screed include various parameters such as the thickness of the screed, ambient temperature, humidity level and air circulation. Drying time usually varies depending on the thickness of the screed; thick screeds may need longer to dry.

Heating systems or drying devices are often used to speed up drying time. As you mentioned, without drying devices, it may generally take up to 60 days for the screed to dry completely. However, this period may vary depending on the conditions of the project and environmental factors.

An important point to remember is that parquet or other coatings should not be applied on the screed until it is completely dry. If adequate drying is not achieved, moisture can accumulate under these coatings, which can lead to problems over time, especially mold growth.

If you want to shorten or control drying time, it is important to monitor the temperature and humidity levels in your project's environment. Additionally, ensuring good air circulation can also positively affect the drying process.
