Screed Drying Times

Liquid Anhydrite Screed

Drys at 1mm per day but this is all dependant on atmospheric conditions.

The minimum thickness of Liquid screed is 35mm on insulated beam and block floors which will be half the drying time of sand and cement

You can force dry after 5 days using Dehumidifier or Boiler

Tiles can be installed when the screed reads 85% Relative Humidity or less

Drys to 75% surface RH after just 14 days

RAPID installation – up to 2000m2 per day. Allows reduced programme time

RAPID finishing – NO spray on curing membranes reducing airborne contamination and eliminating associated safety issues

RAPID strength gain – No reinforcement or fibres required and fewer joints with much larger bay sizes

RAPID setting – allows early foot traffic

RAPID return to full service – can be loaded after just 7 days

RAPID thermal response – greater efficiency of underfloor heating

RAPID completion – allows early floor covering application, e.g. as little as half the time when compared to other standard anhydrite screeds

These work by hydration. Certain chemicals react with the water until they consume all the moisture that is present.

Tiles can be installed after 2 days

Gypsol commissioned a report which finds that drying times were identical between Sand and Cement screed and Anhydrite Liquid Screed.

They found the most important factor was atmospheric conditions. (Get the report here)

Generally, the most important rule to remember is to keep good airflow throughout the building allowing moisture to escape.
