Product Information

Full details

The Bon Tool Big Blue Bull Trowel (22-527) is a high-performance finishing tool designed for professional concrete contractors who need to spread, shape, and smooth large surface areas efficiently. Its key benefit is the flexible blue steel blade that helps eliminate lap marks, resulting in a superior surface finish, though users should be aware that its size requires a handle adapter and significant physical control for optimal results.

Extended Product Information

FAQs

Does this include the handle?

No, this product includes the blade and the wormgear bracket; you will need to purchase a compatible bull float handle separately.

Can this be used on stamped concrete?

No, this is a finishing trowel intended for leveling and smoothing plain concrete surfaces, not for patterned stamping.

What is the benefit of the rounded ends?

Rounded ends help the tool glide over the concrete surface, preventing the corners from digging in and reducing the appearance of lap marks.

How do I adjust the angle of the blade?

Use the adjustment knob on the included #12-372 Wormgear Bracket to rotate the blade to your desired working angle.

Is the blade replaceable?

The blade is permanently attached to the backbone system via the two-rivet design; it is not intended to be removed or replaced individually.

Troubleshooting

The trowel creates ridges during use

Check if the blade angle is too steep; adjust the wormgear bracket to bring the blade closer to a flat angle relative to the concrete surface.

Bracket feels loose or wobbly

Tighten the bolts connecting the bracket to the U-channel and ensure the handle attachment is locked securely.

Blade showing signs of surface rust

Clean the blade thoroughly and wipe down with a light machine oil before storing in a dry area.

Pros and Cons

Pros

  • High-grade blue steel provides excellent flexibility
  • Rounded design minimizes surface gouging
  • Durable U-channel construction ensures long service life
  • Includes versatile wormgear bracket for better control
  • Ideal for covering large concrete areas quickly

Cons

  • Requires a separate bull float handle to operate
  • Larger size can be physically demanding for extended use
  • Not intended for small, confined spaces or detailed edges

Setup, Compatibility & Care

To set up this tool, insert your preferred bull float handle into the #12-372 Wormgear Adjustable Bracket and secure it firmly. Ensure the bracket is tightly bolted to the U-channel backbone before beginning work.

Compatibility: This tool is compatible with most standard bull float handles featuring a button-style or threaded connection, provided they fit the wormgear bracket.

Care: After every use, it is critical to thoroughly clean the blade with water and a soft brush to remove all concrete residue. If concrete is allowed to harden on the blade, it can affect the flatness of future finishes. Periodically inspect the two-rivet fastening points for any loosening due to vibration and apply a light coat of oil to the blade during long-term storage to prevent oxidation.
