Longcliffe launch Longfloor liquid cement screed

Longfloor tanker

Fast-drying floor screed solution for domestic, commercial and underfloor heating applications

LONGCLIFFE Quarries are now supplying Longfloor dry powder bulk binder for the manufacture of liquid cement screeds. 

The Longfloor liquid cement screed system is said to have major advantages over both traditional screeds and anhydrite/gypsum flowing screeds. It can be laid at 10 times the speed of traditional screeds, manual handling is avoided, and a denser, more even surface and creamy smooth finish can be achieved.


Moreover, Longfloor dries at three times the speed of anhydrite/gypsum-based flowing screeds, there is no laitance to sand off, and contamination and blistering issues with wet concrete or cement-based floor adhesives are totally avoided.

According to Longcliffe, the product is not susceptible to cracking, crazing or curling and can be laid in wet areas. It can be used in both domestic and commercial applications and provides good thermal conductivity over underfloor heating systems. Longfloor can be applied down to 25mm thickness in bays of up to 150 sq metres, and a single crew can lay 1,000 sq metres in a day.

The binder consists of superfine high-purity limestone powder plus a suite of dry chemical reagents and admixtures manufactured to BSEN 13813:2002. It is made in a new state-of-the-art factory at Longcliffe’s quarry near Matlock then delivered by tanker to a stockist’s silo where sand, cement, water and a liquid admixture are added. 

Stockists are typically ready-mixed concrete plants, mixer or dry leg. Delivery to customer can be from drum mixer or volumetric trucks. Longfloor liquid cement screed is discharged or more usually pumped into the building, then simply dappled before applying Longcure, a sprayed proprietary curing agent.

As a result of Longcliffe Quarries’ special manufacturing process, Longfloor has a certified 95% recycled content.

Andy Littler, Longfloor director, said: ‘We are very excited about this pioneering easy-to-use screed product. For many years the concrete industry has tried to develop a cement-based liquid screed which flows well, dries quickly and is not prone to cracking.

‘We have now achieved this. The screed industry is witnessing a sea change in favour of cement-based liquid screeds and we intend to make Longfloor the market leader and top-performing benchmark standard.’

Longfloor screed is currently available to screed contractors in the North West, Midlands, South East, London, South West, Humberside and Scotland.
