A diamond trowel blade 20 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 22, for preparing the concrete surface; a backing plate 24 for supporting the diamond bearing surface; and a mounting arm 26 for attaching the trowel blade 20 to the power trowel. A method for mechanically preparing a concrete surface with a diamond trowel blade 20 attached to a power trowel including the surface preparing steps of; selecting the diamond trowel blade 20 with the appropriate grit for the concrete surface, installing the diamond trowel blades 20 on the power trowel, and directing the rotating diamond trowel blade 20 over the surface until the smoothness is attained for the particular grit in use; and repeating the steps until the user achieves the smoothness desired.
A trowel blade with diamond particles that will attach to a power trowel for surface preparation of hardened concrete, the trowel blade comprising:
A method for mechanically preparing a concrete surface with a diamond trowel blade with a compliant intermediate layer attached directly below the backing plate and directly above the diamond bearing surface for surface preparation of floors attached to a rideable power trowel, the method comprising the surface preparing steps of:
A method for mechanically preparing a concrete surface with a diamond trowel blade with a compliant intermediate layer attached directly below the backing plate and directly above the diamond bearing surface for surface preparation of floors attached to a walk behind power trowel, the method comprising the surface preparing steps of:
