Surface Preparation Trouble Shooting
The majority of issues with diamond tools arise due to one of the following reasons:
The tool wasn’t matched to the job, the tool wasn’t used correctly or the machine is faulty.

The final result of concrete grinding dramatically depends on the pouring and curing processes. If the concrete is tamped too hard or inadequately vibrated, solids may sink to the bottom, affecting the outcome significantly.
To clear cloudy surfaces, additional surfaces may need to be removed from the floor to access the aggregate. However, in most cases, this solution may not be viable.
Once an adhesive has discoloured the matrix, saving the floor becomes challenging as there are limited options for restoration.
– Unfortunately, this issue cannot be fixed.
Incorrect specifications can lead to over-exposed diamonds, causing excessive wear and reducing the tool’s lifespan, especially on highly abrasive materials.
– Choose a more rigid bond.
Please note: the wear on abrasive material is generally higher and can only be reduced to a certain degree.
If a tool’s bond doesn’t wear away as intended, diamonds may not be exposed sufficiently, causing the tool to slow down or stop grinding.
– Choose a tool with a softer bond.
– Dress or sharpen the tool with a soft concrete block or abrasive wheel to expose diamonds. If reoccurring, switch to a tool with a softer bond.
– Saturate concrete (without the water puddling) to cool it. Alternatively, introduce sand or use cutting lubricants.
Thick, deep scratches typically result from incorrect application, such as using the wrong grit or operating excessively. Variations in concrete hardness can also contribute to this issue, causing certain areas to scratch more quickly than others.
– Select a finer grit or take more time when grinding more passes and less force/pressure.
– Move slower and go through all steps from a coarser to a finer grit. Remove all scratches before moving on to the next step.
– If many scratches occur, go back and use a coarser grit.
Narrow, deep marks often occur when a tool is too aggressive for the application, indicating that the tool is excessively coarse and aggressive.
– Select a finer grit or a tool with a larger surface area, e.g., a cup wheel rather than a plug, to distribute the pressure over a larger area.
Premature diamond loss is when the segment bonding releases the diamonds easily. Premature diamonds is most likely from the segment being too-soft for the material that is being cut.
– Choose a tool with a harder bond.
– Increase the capacity of dust extraction and clean up the surface if necessary.
In grinding, a step-by-step process is crucial for achieving a high-quality finish. Poor overall finish can be due to tooling scratches, insufficient passes, and too much pressure.
– Choose a finer grit size and reduce the relative speed of the wheel and work piece.
– Use smaller MESH steps
– Less forced pressure and more passes with each tooling.
Using a finer grit, whether with a metal or resin bond, can lead to scratches if foreign objects become trapped between the surface and the grinding tool.
– Check the tool every 20-30mins when grinding to ensure nothing is stuck in between, and clean the area if necessary. If grinding is wet, increase the water supply.
If segments fall off a tool, it could be due to areas of the floor being ‘above grade,’ meaning they were raised above the surface level.
– Cut off/hand grind surface to level or hit areas with a hammer to knock below grade.
– Be very careful when using a hand grinder as too much material can be taken away, especially in low spots.
– Spot grind the concrete with a concrete planer if the spot is above 10mm high.
