Read about heated screeds. A heated screed is a floating screed with pipe work embedded in the screed. Depending on the outside temperature, hot or cold water flows through the pipe-elements. These are put above insulating panels. The screed must only be laid after the pipe work has been tested for leaks. While conventional screeds are mixed on site, liquid screeds are delivered by transport mixers. Listen to a flooring expert giving a lecture on laying a conventional screed. Put the step by step instructions into the right order: 7  Allow the screed to set before walking on it. 9  The next steps depend on the final floor covering. 6  Then finish the surface, use a floating technique to make it smooth. 4  Compact the screed thoroughly with a trowel. 8  Test the screed and make sure it is solid and even. Unevenness of more than 4mm within one meter must be levelled out using some levelling compound. 1  Set measuring points at the right height by means of a laser level. 2  Mix the screed according to the manufacturer’s specifications and spread it with a shovel. 5  Use a levelling board to level out the screed. 3  Link these points with screed material. These pre-levelled stripes indicate the finished screed level. 03 A2 04 A2–B1 listening pn26be Word bank 03 heated screed Heizestrich pipe work Rohrleitungssystem embed einbetten 04 liquid screed Fließestrich set trocknen floating technique Zureibetechnik smooth glatt compact verdichten thoroughly gründlich solid fest even eben unevenness Unebenheit level out ausgleichen levelling compound Nivelliermasse measuring point Messpunkt laser level Lasernivelliergerät manufacturer Hersteller spread verteilen levelling board Abziehlatte pre-levelled vorgeebnet stripe Streifen Mosaic Link the squares showing the same figures by horizontal or vertical lines.
