Floor Screeds

Rapid Drying, Minimum Shrinkage, Rapid Strength

With enhanced performance properties, an ARDEX Ultra Rapid Drying Screed can receive floorcoverings in as little as 4 hours, significantly shortening installation times.

As a result, our products have been specified on many time-critical projects where minimal disruption and fast turnarounds were essential;
including King’s Cross Underground Station and Selfridges Foodhall, where work was completed overnight and areas reopened to the public the following morning.

In addition, all ARDEX products perform reliably in typical UK site conditions, and offer the following fast track benefits over traditional screeds:

  • The screeded area can be walked on in hours, as opposed to the 7 days that traditional screeds require as per BS 8204.
  • Floorcoverings can be installed in as little as 4 hours, compared to the months of drying a traditional screed may require.
  • ARDEX Screeds will pass a BRE Screed test in as little as 6 hours, rather than 2 weeks with conventional screeds.

If you’re working on a time-critical project, go for ARDEX A 38 Ultra Rapid Drying Screed. It’s walkable in only 3 hours, receives ceramic, or stone tiles from 4 hours, and resilient floorcoverings from just 48 hours. Used for both internal and external locations.

For a quick screed that also combines good workability and economy, use ARDEX A 29. It offers outstanding performance at an economical 1-part cement to 7 parts sand mix with an extended 90 minute working time. Whilst still being fast enough to receive tiles from 24 hours, and resilient flooring from only 7 days.

For a bagged liquid screed, ARDEX offer ARDEX A 70 GYPFLO
Quick-drying, flowable Calcium Sulphate Screed. It drys twice as fast as standard Calcium Sulphate screeds, from as little as 14 days!
