Screed Drying Times
Cemfloor Liquid Screed
At a depth of 50mm the drying time is 21 days and up to 75mm the drying time is 21 days. However this is all dependant on atmospheric conditions.
The minimum thickness for liquid screed on insulated beam and block floors is typically 40mm, offering a thinner profile than traditional sand and cement screed and significantly faster drying times—often up to three times as quick under the same conditions.
You can force dry after 7 days using the underfloor heating or dehumidifiers (if UFH is not available).
Before Flooring can be laid on Cemfloor, the screed should typically have a moisture content of 75% relative humidity (RH) when tested using an in-situ hygrometer.
What are the benefits of using Cemfloor Liquid Screed?
Dries to 75% surface RH after just 21 days when installed at the recommended depth of 50mm
Quick installation – up to 2000m2 per day. Allows reduced programme time
Rapid finishing – NO spray on curing membranes required, reducing airborne contamination and eliminating associated safety issues
Incredible strength gain – No reinforcement or fibres required and fewer joints with much larger bay sizes
Accelerated setting – allows early foot traffic 24-48 hours after installation
Fast return to full service – can be loaded after just 7 days
Enhanced thermal response – greater efficiency of underfloor heating
Swift completion – allows early floor covering application, e.g. as little as half the time when compared to other standard anhydrite screeds (which dry 1 day per mm laid e.g 50mm = 50 days drying time)
