Abstract:
A diamond trowel blade comprises diamond particles that will attach to a power trowel for surface preparation of hardened concrete surfaces. The diamond trowel blade includes a diamond bearing surface ; a backing plate ; an intermediate layer ; and a mounting means for attaching the trowel blade to the power trowel. A method for mechanically preparing a concrete surface with a diamond trowel blade attached to a power trowel including the surface preparing steps of: attaching the diamond trowel blade with the power trowel; selecting the diamond trowel blade with the appropriate grit for the concrete surface; directing the rotating diamond trowel blade over the surface until the smoothness is attained for the particular grit in use; and repeating the steps of selecting, directing, and repeating until the user achieves the smoothness desired.
