How Long Does Liquid Screed Take to Dry?

Liquid screed needs sufficient time to dry before the final floor covering is installed. The exact drying period varies according to the screed product, thickness, ventilation, temperature and site conditions, so there is no single timeframe that applies to every project.

What affects drying time?

Screed thickness is one of the most important factors. A thicker application generally takes longer to dry than a thinner one. Room temperature, humidity and ventilation also make a significant difference.

Good airflow can help moisture leave the screed, but drying should be controlled rather than relying on excessive heat. Following the screed manufacturer’s guidance is essential.

When can flooring be installed?

Liquid screed should not simply be judged as dry because the surface feels hard. Moisture levels should be checked using an appropriate testing method before installing timber, vinyl, tiles or other floor coverings.

This is particularly important for renovation projects in London properties, where existing building conditions can affect ventilation and moisture levels.

Underfloor heating can also influence the drying and commissioning process. Where it is incorporated into the floor, the heating system should be commissioned according to the screed and underfloor heating manufacturer’s requirements before the final floor finish is installed.

For more information, see our guide to liquid screed versus traditional screed to understand how the two systems differ.

How can drying be managed?

The screed should be protected during the early stages and the room kept suitably ventilated. Avoid adding unnecessary water or exposing the floor to unsuitable conditions. Professional preparation and correct installation can also help create more predictable drying conditions.
