I often get asked "precisely what is screeding?" In short, screeding (at least as practiced in the UK) is a thin, top layer of material such as for example sand or cement, that is poured on top of structural concrete or insulation. This material is then levelled and smoothed so it's the same height as the forms, or guides, that surround it. Imagine an individual measuring a cup of flour, then using a knife to smooth the top. The flour is compacted and contains a smooth top layer. That is screeding in its most elementary form.
The most common use of screeding is in gardening and landscaping. The contractor pours concrete into the forms or guides and allows it to fill to a certain height. To guarantee the concrete will undoubtedly be level when it dries, screeding must be done now. To get this done properly, a tool such as a long little bit of aluminium or timber, which is larger than the guides, is slowly moved over the guides. This tool is also moved in a backwards and forwards motion while screeding to level and smooth the concrete, which ensures a perfectly level floor. There are also industrial tools available, which are ideal for use over larger areas.
There are four main types of floor screeding designs:
Bonded screed
Unbonded screed
Floating screed
Underfloor heating screed
Bonded Screed
This must be laid on a shot-blasted / scabbled concrete base, and be bonded utilizing an adhesive such as for example PVA, SBR, epoxy resin or good old-fashioned cement.
Unbonded Screed
They are not bonded directly to the concrete base, but are intentionally debonded with the use of a DPM (damp-proof membrane).
Floating Screed
Floating screed can be used on top of rigid insulation boards. It is strongly recommended that the thickness of a floating screed should be between 65 and 90 mm.
Underfloor Heating Screed
A traditional sand and cement screed can be an ideal selection of screed for underfloor heating. Under floor heating manufacturers and suppliers generally recommend the very least screed depth of 60 mm to utilize with their systems.
The delivery, mixing, and pumping of screed is normally from the single vehicle which pours the screed directly from the mixing pan to the floor at a variety of around 60 metres. For smaller applications, the screed can be hand laid.

Alternatively other finishing materials can be applied on top.
