Concrete grinding is the simplest and most efficient method for leveling and restoring a concrete floor. While the grinder removes coatings, it creates the perfect base for a new floor covering.

Material can be removed by either using a dry grinding or wet grinding method. While both methods have the same end result, there are a few differences in the process:

Dry
Production rates will be slower on harder materials than wet grinding
Softer bond segments are required in order to encourage even segment wear
Scratches from diamond grit will not be as deep when compared to wet grinding
More heat is generated by the diamond segment
Cleaner work environment
Wet
Production rates will be higher than when dry grinding
Diamond segments will wear faster due to the presence of abrasive slurry
Scratches from diamond grit will be deeper
Longer clean up time

Which method to choose is a personal preference. When either dry or wet grinding, start with a coarse grit diamond tool and progressively work down to fine grit tools — depending on the desired specification. Changing the size of the diamond grit to a smaller particle/grit size gradually removes scratches in the concrete and creates a fine scratch pattern. This creates a good bonding surface for a new floor covering.

After the grinding process has been completed, the final result is a good base for either a polished floor or another surface. Ending with the perfect base floor means the next step(s) will be finished more efficiently. Taking the time to think through the process and plan accordingly will make the project more efficient, easier and the customer will be happier in the long run.
