There is no precise standard measurement for the surface area that a sanding belt can cover, as this depends on many factors:

Factors influencing the surface area covered

1. Belt dimensions: Sizes vary according to the sanding machine model.
2. Material being sanded: The hardness of the wood or floor influences the wear of the belt.
3. Sanding technique: The method and the pressure applied affect the lifespan of the belt.
4. Grain of the belt: Larger grains generally wear out more quickly.
5. Quality of the belt: Higher quality belts such as those from Primex often last longer.

Approximate estimate

On average, an abrasive belt can cover between 3 and 6 m² before needing to be replaced. However, this estimate can vary considerably depending on the specific conditions of the work and the experience of the user.

It is important to note that this estimate is very general and may not accurately reflect all scenarios. For a specific project, it is recommended that you consult the sander manufacturer or a sanding professional to obtain a more precise estimate based on your particular situation.
