Floor screeds. A floor screed is usually a cementitious material made from a 1:3 or 1:4.5 ratio of cement to sharp sand. It may be applied onto either a solid in-situ concrete ground floor slab or onto a precast concrete floor unit. There are many proprietary screeds on the market and information about these can be obtained from the manufacturer.

The drying of the screed must not be accelerated by heat or ventilation, since too quick a drying may cause hair cracks. If the temperature in the levelled room is higher than normal, the relative humidity very low, or if the levelled floor surface is exposed to direct sunlight, we recommend covering the floor with a tarpaulin as soon as it is ...

When it comes to the screed, thicker screeds will take longer to warm up, but will then retain the heat for longer. The minimum British Standard is 65mm of hand-mix (3:1 sand/cement) or 50mm of liquid (or self-levelling) screed. Such a thickness will take about one hour to heat …

1) Setting up the heating mantle • Choose the right size of the heating mantle and put it on a magnetic stir plate. ! The heating mantle should fit the flask size. The temperature will be difficult to control if the heating mantle lacks contact with the flask. The heating mantle will overheat or burn out if left unintended for too long.

Both screeds are also equipped with a new heating system that heats the screed plate, tamper and pressure bars 50 percent faster than before and much more uniformly. The SB 300 replaces the SB 250 and can be combined with the SUPER 1800-3 (i), the SUPER 1900-3(i), the SUPER 2100-3(i) and the SUPER 3000-3(i).

If you want an efficient setup from your water-based or wet underfloor heating (UFH), and you're working with a solid floor, then you'll need to lay the pipework into something that aids the transfer of heat. That's where screeds come in. The two most common options are traditional 'dry' versions and 'self-levelling' types. They not […]
