It is correct to say that wet screeds can only be laid after determining that they are ready for laying (in this case because they have dried out). It is the task of the floor layer or, if a screed with additives was used, the task of the screed layer to indicate HOW the residual moisture content of the screed should be measured and at what value the screed is ready to be laid.

There are screed additives that deliver on the manufacturer's promise. This means that it is quite possible that the screed will be ready to be laid in a few days. In the case of some additives, it even happens that once the screed is established ready to be laid, the screed must be laid immediately to eliminate the possibility of re-wetting. This is rare, but it exists!
