Transitional pads are intended to smooth out scratch marks left by metal-bond grinding and prepare the surface for polishing. If scratches remain visible after this step, it usually indicates a mismatch between the pad, the surface condition, or the previous grinding process. Understanding the reasons behind this is crucial to maintaining surface clarity and avoiding costly rework.

A common reason is inadequate refinement during the metal grinding phase. hybrid transitional diamond tools are designed to refine scratch patterns left by metal grinding, not to remove deep gouges or correct major surface unevenness. If coarse grind marks are still present, the transitional pad may simply highlight them instead of eliminating them. It is essential that each grinding step completely removes the scratches from the previous grit before proceeding.

The choice and condition of the pad also significantly affect the outcome. Using a ceramic bond edge wheel that is too aggressive for the surface can create new scratch patterns instead of blending the existing ones. Worn or glazed pads may slip over the floor, reducing contact and causing inconsistent results. Regular inspection and timely pad replacement help ensure uniform surface refinement.

Machine settings also impact scratch formation. Excessive pressure or high rotation speeds can cause the pad to cut unevenly, especially on harder concrete or terrazzo surfaces. Applying controlled pressure and maintaining steady movement allows the pad to work as intended, gradually softening scratch edges rather than creating new marks.

Application technique and floor cleanliness are often overlooked but important factors. Debris left on the surface can get trapped between the pad and the floor, causing random scratches that look like tool marks. Professionals using TransGrind transitional pads stress the importance of thorough cleaning between steps and consistent machine control to achieve a smooth, scratch-free transition to polishing.

When used properly, concrete transitional tools serve as a bridge rather than a cutting stage. Paying attention to preparation quality, pad selection, machine settings, and site conditions ensures the surface progresses smoothly toward polishing, delivering the clarity and finish expected from a professional grinding system.
