Screed Vibrator

The vibrating screed is placed on top of the concrete with the engine running, and the handle is held to prevent the machine from jumping on the concrete. The screed should remain in contact with the concrete and should not exhibit any resistance; it should glide smoothly over the concrete.Screed is a thin layer of material usually laid on top of a concrete subfloor. It can go in between concrete and other layers to help even it out or to provide a better surface for adhesives. The concrete subfloor attaches to your floor joists to add support for the finished flooring.
