The MBW ScreeDemon™ 2.0 is a professional-grade wet screed featuring a Honda GX35 engine and a reinforced E-coated aluminum frame. It is designed to reduce hand/arm vibration by up to 90% while utilizing a triangular beam design for consistent vibration across the slab. New ergonomic features include dual lifting points and a hand-operated kickstand for improved site maneuverability.

Low-Vibration Engineering
The MBW ScreeDemon™ 2.0 is engineered specifically for the professional contractor, focusing on a design that simplifies the screeding process while maintaining high performance. A primary focus of this version is operator health; the unit reduces hand and arm vibration by 50% to 90% when compared to competing models. This significant reduction in physical strain allows for longer periods of use without the typical fatigue associated with wet screeding.
Structural Integrity and Uniformity
The drive unit utilizes a signature back-to-back triangular beam design. This specific geometry is chosen because it ensures that vibration is delivered uniformly across the entire length of the beam, preventing inconsistent finishes on the concrete surface. The frame is now E-coated aluminum, which provides a durable finish that resists concrete buildup and makes the cleaning process faster at the end of a shift.
Enhanced Maneuverability and Ergonomics
Several mechanical updates improve the daily handling of the machine. The version 2.0 features a higher central lifting point and an additional lifting point at the front of the drive unit, making it easier to transport around the job site. Furthermore, a hand-operated kickstand has been integrated near the handle, allowing the machine to stay upright and accessible when not in motion, protecting the engine and frame from ground debris.
Reliable Power Generation
At the heart of the unit is the Honda GX35 petrol engine, a 4-stroke system known for its reliability in construction environments. Delivering 1.5 hp at 7000 rpm, the engine provides the necessary force to drive the vibrating beams through various concrete slumps. The 35 cm³ displacement ensures a compact power-to-weight ratio, keeping the overall operating weight of the unit at a manageable 29 lb.
What’s New: MBW 501H ScreeDemon Improvements
- Increased Durability: The unit now features a high-strength, die-cast e-coated aluminum frame, making it more robust and easier to clean than the previous version.
- Superior Clamping Force: The new clamping mechanism is engineered to deliver 20% to 30% more clamping force than earlier models.
- Improved Ergonomics: The lifting handles have been redesigned with a taller main handle for easier movement on the slab and a dedicated front handle for effortless transport.
- Advanced Kickstand: A brand-new, conveniently placed kickstand allows the operator to stand the screed up without having to bend over.
- Vibration Reduction: The mount retention system, utilizing low durometer isolators, significantly reduces hand-arm vibration by 50% to 90% compared to typical competing screeds.
- Added Convenience: For quick field adjustments, MBW has included a 9/16" wrench that stores directly on the kickstand.
