With natural drying it is difficult to estimate the length of the drying process, but also with building dryers it is virtually impossible to determine the exact drying time. In general, during wet periods, use of the appropriate building dryers will reduce the drying time by a factor of 4 as compared to natural drying. Some further indications are given below.
The first 4 cm of a screed each take about one week to dry, for thicker screeds an exact calculation is required. Please note that drying may not be started until 7 days have elapsed since the installation of the screed.
In contrast with conventional sand cement screed, you can speed up the drying process if you set up building dryers and fans 48 hours after the installation of the anhydrite floor. In this case, a drying time of only two to three weeks will be required. Please note: if you wait more than seven days after the installation, the anhydrite floor will take much more time to dry. The drying time is then comparable with that of a sand-cement screed.
Stone walls, stucco and calcium silicate blocks can also be dried in 14 days provided they are not saturated with moisture. To determine whether building materials are sufficiently dry for finishing, a variety of measuring equipment is available. Read more tips here on hiring measuring equipment.
