Setup
Assembly Instructions
The QLT Magnesium Bull Float comes with the Rock-It 2.0 Bracket pre-attached to the blade. To prepare the tool for use, you will need to attach a compatible bull float handle (sold separately) to the bracket.
- Inspect Components: Before assembly, ensure all parts are present and free from damage. This includes the bull float blade with the attached Rock-It 2.0 Bracket and your bull float handle.
- Attach Handle: Insert the end of your bull float handle into the receiver on the Rock-It 2.0 Bracket. Ensure the handle is fully seated and aligned with the bracket's locking mechanism.
- Secure Handle: Tighten any locking screws or levers on the Rock-It 2.0 Bracket to firmly secure the handle in place. Refer to your specific handle's instructions for proper attachment.
Operating Instructions
Using the Bull Float for Concrete Finishing
The bull float is used to smooth and level freshly poured concrete surfaces, bringing the cream to the top and preparing the slab for subsequent finishing steps. The Rock-It 2.0 Bracket allows for easy adjustment of the blade angle during operation.
- Initial Pass: After screeding the concrete, begin floating. Position the bull float on the concrete surface with the leading edge slightly raised.
- Pushing Stroke: Push the float across the concrete, maintaining a consistent, slight angle. The float should glide smoothly, filling in voids and leveling the surface.
- Pulling Stroke: At the end of the push stroke, adjust the handle to slightly raise the opposite edge of the float. Pull the float back towards you, overlapping the previous pass.
- Adjust Angle: Use the Rock-It 2.0 Bracket's mechanism to adjust the blade angle as needed to achieve optimal smoothing and to prevent the float from digging into the concrete.
- Work Systematically: Continue floating in overlapping passes until the entire surface is uniformly smooth and level.

Maintenance
Proper maintenance will extend the life of your QLT Magnesium Bull Float and ensure its continued performance.
- Cleaning: Immediately after each use, thoroughly clean the bull float blade and bracket. Remove all concrete residue using water and a stiff brush. Do not allow concrete to dry on the tool, as it can be difficult to remove and may damage the blade surface.
- Inspection: Regularly inspect the blade for any nicks, dents, or excessive wear. Check the Rock-It 2.0 Bracket for loose fasteners, signs of corrosion, or damage. Ensure the handle connection mechanism is functioning correctly.
- Storage: Store the bull float in a clean, dry place away from direct sunlight and extreme temperatures. Hanging the float can help prevent warping of the blade.
- Lubrication: Periodically apply a light coat of rust-inhibiting oil to any moving parts of the bracket to ensure smooth operation and prevent corrosion.
Troubleshooting
This section addresses common issues you might encounter with your bull float.
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven concrete surface after floating | Incorrect blade angle; inconsistent pressure; concrete too wet or too dry. | Adjust blade angle using the Rock-It 2.0 Bracket. Apply even pressure. Ensure concrete consistency is appropriate for floating. |
| Float digs into concrete | Leading edge too low; concrete too soft. | Raise the leading edge slightly. Wait for concrete to stiffen slightly before floating. |
| Handle feels loose or wobbly | Handle not securely fastened to bracket; worn bracket components. | Ensure handle is fully inserted and locking mechanism is tightened. Inspect bracket for wear and replace if necessary. |
| Difficulty cleaning dried concrete | Concrete allowed to dry on blade. | Always clean immediately after use. For dried concrete, use a concrete remover product or carefully scrape without damaging the blade. |
