Rake marks and rough surfaces come down to the same root causes: machine condition, tooling match and technique. Fix it by dressing the disc: abrade aggressively through an abrasive dressing block, a scrap of concrete block, or a glazed silica-free brick for 30-60 seconds to open new diamonds. If glazing keeps happening, the bond is too hard for the material and you require a softer-bond disc.

Getting this part right saves a full re-pass later.
What you should know before starting.
Diamond tooling work by micro-fracturing the old crystals so new sharp ones emerge.
Contractors who skip this stage usually end up redoing the floor.
The key points in practice.
Switch from a hard matrix to a softer bond for soft concrete, or vice versa.
This is where most crews get it right - or lose time.

Loading means the segments are caked with soft material (epoxy resin, glue, paint) — you will see black or colored buildup.

The key points in practice.
Commercial dressing stones are resin-bonded abrasive blocks designed to open diamond segments.
This is where most crews get it right - or lose time.
A closer look at the details.
After dressing, keep the disc sawing freely by stopping dwell, using enough downward pressure from equipment weight, and matching bond to concrete.

What you should know before starting.
For cup wheels, when the steel hub shows through on two or more segments, retire it — bare steel will score the floor.

A: For most jobs, Resin pads glaze when pushed on soft coating layers. Lightly dressing on a dressing stone restores bite, but a loaded resin pad is in most cases done.
A: In short, New discs frequently require a 30-second break-in on an abrasive block to expose the first layer of diamonds. Skip this and operators think the disc is defective.
A: The practical answer is, Marginally, but a dressed disc cuts like new and saves hours. It is far cheaper than replacing the disc.
A: For most jobs, No — forcing a glazed disc just generates heat and can crack segments. Dress or change the bond instead.
