Midwest Rake® S550 Professional™ EasySqueegee® Blade

This is the replacement blade for the Midwest Rake S550 Professional EasySqueegee, offered in 18, 26 and 27 inch widths and in flat stiff, flat flex and notched profiles in the 15-20, 25-30, 40-45 and 50-60 ranges.

The notch is the control. On a coating job the squeegee is what meters the material onto the slab, and the notch size determines how much of it goes down per pass. Choose a notch too small and you starve the floor and fight to reach coverage. Choose one too large and you put down more material than the system is designed to carry, which costs money on every square foot and can cause the coating to behave differently than the data sheet says. Pick the notch that matches the film build your coating manufacturer specifies for the system you are installing, then back-roll to even it out.

Flat blades do a different job. A flat stiff blade pushes and moves material, which is what you want for spreading a broadcast base coat quickly or pulling excess. A flat flex blade follows the slab more closely and is better for pulling a thin, even film without leaving ridges. Neither one meters material the way a notched blade does.

Width is about the room. The 27 inch blade covers open field with the fewest passes, which matters on timed material, and the 18 inch works bays, garages and areas with obstructions where a wide blade cannot complete a clean pull.

Blades are wear items. Nicks, cured material on the edge and uneven wear all telegraph into the finished floor as lines and lap marks, so change them before a floor you care about. Confirm your frame is the S550 Professional before ordering, since squeegee blade mounting differs between platforms.
