Movement joints, control joints, what are they?
Movement joints separate the screed through its entire thickness e.g. by using expansion profiles and serve the purpose of accomodating thermally influenced length elongation.
Control joints separate the screed slab by a cut into the top third of the screed usually by a trowel cut. This control joint serves the purpose of forming a pre-determined crack point to accomodate shrinkage stresses as the screed dries out e.g. in door thresholds.
How is it best to dry a screed?
All installed screeds must be protected from draughts. In the first week after laying the screed, only the windows on the gable end should be opened a crack. Afterwards it is recommended that the air is completely exchanged (completely open the windows) for 1.5 hours, three to four times a day.
