The KZW concrete screed takes two forms: the surface finishing version and truss screed. The first type of screed is driven by either a gasoline engine or an electric motor. It is essentially a purpose-made aluminum alloy beam. Its lightweight structure lends ease with which the screed can be operated. Choices of various blades can be made by users according to the construction site requirements. The screed is available in lengths varying from 1m to 6m. Weighing as little as 12kg, it is one of the lightest portable screed versions you can ever obtain on the market.

The truss screed is most often used to remove slurry, and smooth out the high or rough spots on the concrete slab. It is commonly seen on the bridge, highway, and workshop, airport, and square construction sites. Its main framework is made of steel or aluminum, giving rugged and impact-proof features. The product can be made into various lengths ranging from 4m to 28m.

The power concrete screed is one of the lightest equipment for concrete surface finishing. On the concrete pouring site, the concrete is first placed into the pre-set formwork. Then workers use the shovels or concrete rakes to spread out the concrete. Before the concrete shows the first sign of setting, push the power screed back and forth on the slab to level out the high and low spots. Surface finishing work with the power screed is hard work. The wider the concrete pour is, the more impractical it is to use the concrete screed. Allow the screed beam to extend beyond the whole width of the formwork so that operators can hold the protruded part for operation. Move the screed slowly along the voids on the slab to make sure the hollow is filled. Lift the screed off the slab, and go back to make a second pass by that area.

The back-and-forth motion of the concrete screed may get small bits of gravels sink down into the concrete while the air bubbles will rise to the surface, thereby consolidating the concrete and improving the concrete strength. Pouring concrete and smoothing its surface on your own saves money otherwise spent in hiring workers do the work. But you should be acknowledgeable enough to perform the task. Pouring concrete requires a lot of strength and endurance as you work against the clock to level out the concrete before it settles firmly. Remember to ask the concrete delivery man about the mixture of the concrete when he or she arrives at your construction site.

When the concrete surface is relatively smooth, you can change to the finish float to fine tune the surface with the edge trowel. Pour concrete screeds during warm days for the best results. On a cold day, you can add calcium to the concrete mix to help drying. In a hot summer, prepare a garden hose and sprinkle water over the concrete surface as soon as it has hardened. In this way, you can temper the concrete.
