The Impact of Excessive Moisture on Terrazzo Floor Grinding
Dec 23 , 2024

Terrazzo floors are commonly found in commercial buildings, airports, and even residential properties. However, maintaining the quality and appearance of a terrazzo floor requires regular maintenance, including grinding to remove imperfections and restore its shine. One important factor that greatly affects the grinding process is moisture.


Moisture in a terrazzo floor can cause several challenges during the grinding process. Firstly, excessive moisture can weaken the bond between the terrazzo chips and the binder, leading to delamination or debonding. This not only compromises the structural integrity of the floor but also creates a rough and uneven surface that is difficult to grind effectively. Additionally, the presence of moisture can result in softer areas on the floor, which may grind at a different rate compared to the surrounding areas. This can cause an inconsistent finish and an unbalanced appearance on the floor.

Furthermore, moisture also affects the performance of diamond grinding tools. Excessive moisture can result in clogging of the diamond grinding pads, reducing their effectiveness and slowing down the grinding process. The trapped moisture can create a slurry, mixing with the abrasive particles and hindering metal bond grinding tools’ ability to remove the imperfections from the terrazzo surface. As a result, the grinding process becomes less efficient and time-consuming, leading to unnecessary delays and increased costs.


To mitigate the negative impact of excessive moisture on terrazzo floor grinding, proper moisture management is essential. Before initiating the grinding process, it is crucial to conduct moisture testing on the floor surface. Various moisture testing methods are available, including the calcium chloride test or the relative humidity test. These tests help determine the moisture content within the terrazzo to ensure it is within an acceptable range for grinding. If high moisture levels are detected, it is necessary to address the issue before proceeding with grinding.
