When MBW develops a new product, they look for deficiencies in products already in the marketplace. Portable wet screeds suffered 4 serious shortcomings:
Mechanical
Wet screeds were prone to high maintenance, especially in connection to drive mechanisms between the engine and exciter. The ScreeDemon™ has a simple, durable, low-cost rubber isolator that drives the eccentric.
Functional
Most screed and screed bar combinations produce irregular vibration along the length of the screed bar. Not only is the concrete exposed to highly variable levels of vibration but cream levels vary from spot to spot along the screed bar. The back-to-back triangular construction of the ScreeDemon™ bar is extremely rigid and minimises variability in the transmission of vibration.
Most screeds bolt to their screed bars.
Hardware threads are compromised by the concrete and assembling or removing the screed becomes such a problem that crews often don't disassemble for cleaning or transport. The ScreeDemon™ simply clamps to the specially designed bar.
No holes to weaken the screed bar. No threads to complicate assembly/disassembly. The ScreeDemon™ goes together and comes apart in seconds.
The patented handle reduces vibration to the operator yet maintaining rigid control when needed.
Direct engine to eccentric drive via a rubber flex shaft, (unlike metal flex shafts that are wire wound cables), reduce service and maintenance.
Clamp onto the bar with captured hardware easily exchanges bars, allows relocating to any point on the bar and is easily removed for transportation protecting the motor.
Double diagonal design extruded magnesium bars for maintaining strength and rigidity, available up to 24 feet.
Exciter mounted directly to bar for effective transmittal of vibration to the concrete up to 16 feet, up to 24' with two motors.
A permanently sealed eccentric system reduces service and maintenance. 8. Engine to eccentric is fully protected with three shock mounts reducing engine failure.
Adjustable handle for operator height and collapsible for transporting. Includes kickstand.
Lifting handle centred and balanced for effortless lifting.

Key Features
Operator Health & Safety
All wet screeds tested by MBW exposed operators to excessive hand/arm vibration. The ScreeDemon™ patent-pending mount retention method enables the use of low durometer isolators without loss of operator control. Hand/arm vibration is 50 to 90% lower than competitive screeds.
