Premflow is a high-strength free-flowing screed made with an anhydrite binder rather than cement. It is placed by pump, enabling fast and easy coverage of areas of up to 2000m2 in just one day. Premflow is capable of receiving all floor coverings.

Thinner than conventional screeds and featuring high thermal conductivity, it is an ideal choice for underfloor heating systems. The screed is suitable for foot traffic after 24 to 48 hours and partitions can be erected after 7 days. Full drying takes just 40 days or sooner if force dried after 7 days.

As well as being cement-free, Premflow has an overall recycled content of 35% - making it is a sustainable choice. Additionally, the screed is free from protein and is therefore resistant to bacteria growth, making it an excellent choice for use in care homes and hospitals.

CE marked and manufactured to the requirements of BS EN 13813 under a quality scheme certified to ISO 9001

Ethical Risk Index

This Radar diagram illustrates the level of ethical risk associated with a specific stone. Ethical risk is plotted against the 10 ten measures of the ERI, with each value drawn from reports produced by independent ethical auditors, engaged by Marshalls to provide non-biased and honest reporting into levels of risk in that supply chain.

Each of the 10 measure is designed to recognise different and discrete sources of ethical risk. This produces a bespoke, fit for purpose framework designed specifically for the requirements of the stone industry. The radar diagram itself also compares the Marshalls supply chain to the wider industry in that stone, giving users a working comparison of Marshalls supply chain to the industry average, in the opinion of the auditor.
