HOW LONG WILL FLOW SCREEDING TAKE TO DRY?

Following installation, the environment must remain sealed for 2 days. For the flow screeds adequate protection from rapid drying or draughts should be provided for the first 48-72 hours but thereafter the relative humidity of the building should be low to allow moisture release from the screed and facilitate drying. Failure to provide the desired conditions can prolong screed drying times considerably and may lead to delays in the construction schedule.
Under ideal drying conditions (a warm, well-ventilated room) our screed dries at a rate of 1mm/day up to a thickness of 40mm and then at a rate of 1⁄2 mm/day for thicknesses above this.

Example: 50mm Liquid Flow Screed Drying time: (40mm*1 day) + (10mm*2days) = 60 Days (2 months) NB: Drying of screeds and can be greatly influenced by individual site conditions.

The above example is for guidance only.

Drying times can be reduced by the provision of good ventilation, open windows and doors in good weather, removal of laitance as recommended, the use of dehumidifiers and by force drying of the screed using under floor heating.

Dehumidifiers may be used as early as 72 hours after the placing of flow screed to assist with drying. It is important that a closed system is employed to ensure that any moisture extracted from the environment during operation is removed. Any water collected should be removed regularly.

Force drying of flow screed can begin as early as 7 days following installation of the screed by various methods. Commissioning (heating & cooling procedure) of under floor heating systems. Set flow temperature to 20-25oC, maintain for a minimum of 3 days and then gradually increase the temperature in Max 5oC increments to maximum operating temperature. This should be maintained for a further 7 days (water temperature should not exceed 55oC for screeds), prior to returning to ambient temperature again in Max 5oC increments.

Fossil fuel fired heaters (E.g. Gas heaters) must be avoided as they will raise humidity.

Specialist drying mechanisms, such as vacuum dewatering, cocooning and microwave technology. These procedures should only be carried out by specialist contractors.


IMPORTANT: After drying the screed, the residual moisture content must be determined using one of the approved test methods to demonstrate suitability for acceptance of floor finishes.

NB: Drying of screeds and can be greatly influenced by individual site conditions.
