A screeding level is simply a long, thin length with straight sides and a box profile.
Dimensions
Screeding levels are available in different lengths: the choice is dependent on the job you are doing. They can generally be found at lengths between 1.8 and 3.0m (about 6 and 10ft).
The depth of a screeding level is approximately between 20 and 120 mm (about 4″ and 8″).
Screeding level width is also variable. They can range from 100-200 mm (13/16″- 4¾”). However, thinner tools may not withstand prolonged use as well as the wider varieties.
Handles
Handles make the screeding level more ergonomic and easier to use. They generally come in the form of slots within the tool rather than external add-ons (see below). This means they can last longer and don’t interfere with the straightness of the tool.
Alternative handle design
Some screeding levels, generally much larger industrial usage ones, have a handle which is attached to the top of the level.
End caps
The screeding level is hollow, which makes it lighter, but this means that the ends are open unless plastic end caps are used. These prevent debris getting inside the tool; which would make it dirty and heavy.
Vials
Some screeding levels are equipped with vials similar to the ones usually found on spirit levels. These are spirit-filled tubes, left partially unfilled in order to create a bubble which can be used to gauge if a surface is level.
They are useful on a screeding level for ensuring the tool is being used accurately to apply flat flooring. Some screeding levels come with three differently angled vials: horizontal, vertical and 45 degrees. However, the 45-degree vial is being discontinued and may eventually disappear.
