Liquid / flowing screed is a blend of binder and selected aggregates mixed with clean potable water in order to produce a flowing pumpable screed. This is ideal for application over warm water and electric underfloor heating systems.
Underfloor heating will be effectively carried out through the screed being produced to a controlled flowable consistency which will fully encompass the heating pipes. As well as this, the elimination of voids will result in uniform heat transfer and maximised thermal efficiency of the underfloor heating system. At Central Flow Screed and Underfloor Heating, we use an extremely low shrinkage and therefore we minimise the risk of curling and cracking.
Our environmentally friendly screed will be ready for foot traffic within 24-48 hours. This will not need reinforcement and no curing will be required.
The area to be screeded must be made watertight to prevent leakage. The polythene slip membrane installed over the insulation must be overlapped and sealed to prevent loss of screed. The ideal flow 230 – 250mm is measured using the DIN1060 flow ring whilst the minimum cover to pipes or cables must be 30mm.
