ScreeDemon Screed
ScreeDemon Concrete Screed
When MBW develops a new product, we 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 no metallic shaft connection. A simple, durable, low cost rubber isolator 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 minimizes 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.
Operator Health & Safety
All wet screeds tested by MBW exposed operators to excessive hand/arm vibration. The ScreeDemon's patent pending mount retention method enables use of low durometer isolators without loss of operator control. Hand/arm vibration is 50 to 90% lower than competitive screeds.
Patented

- minimizes variability in vibration
- clamps to ScreeDemon - no holes or hardware through bar
- is attached or removed from screed in seconds for cleaning/transport
- allows for offsetting of screed for working under protrusions
