Vibrating screeds not only make a job less labor-intensive, they also let you do it faster and more efficiently. Some manufacturers claim that using a vibrating screed can cut finishing costs up to 50%. Savings like that can allow you to do more jobs at greater profit.
The concept behind the vibrating screed is simple. Take a wooden 2x4, metal angle, or just about anything else that will work as a screed and vibrate it between 2,500 and 10,000 times per minute. Production rates of 10 to 15 feet per minute are claimed by most manufacturers.
Vibrating screeds are available in several types: beam, flat, truss, roller, and vehicle-mounted. Generally, air, gasoline, or electric power sources are available on beam and float screeds. Truss screeds can be specified with air or gasoline power sources. Roller and vehicle-mounted screeds use gasoline or diesel engines.
