Proper storage of abrasives is essential to ensure that they work at their best and last longer. Otherwise, their performance and lifespan can suffer. In this article, we will explain the best way to store abrasives, using sanding belts as an example.

It is recommended to store abrasive materials within a temperature range of 60°F-80°F while maintaining an ideal relative humidity of 45%. The level of relative humidity is a crucial factor in abrasive storage, as issues may arise when it fluctuates. For instance, the humidity levels in heated rooms tend to drop by approximately 15% at the beginning of the heating season while it goes up to 80% or even more after extended periods of rainy or foggy weather.

If it's difficult to maintain ideal temperature and humidity conditions, ensure that coated abrasives are stored away from concrete floors, heaters, hot air ducts, and dampness.

Remove abrasive belts, especially wide ones, from their original packaging at least 24 hours before scheduled use and hang them on a rack near the machine you will use them on. This will allow the belts to adjust to the temperature and humidity of the workspace, which will help to ensure their safety and effectiveness.

The racks should ideally have non-metallic hangers that are level with the ground at least 4 inches in diameter, and situated 4 inches from the wall. Additionally, the belts should be positioned at least one foot off the floor and not in contact with each other. It is also important to avoid storing the belts on concrete floors or in areas that could become damp.

Improper storage of sanding belts can impact the safety of the belt. Humidity can weaken the belt joint and cause it to snap during use, which can lead to injury. By following these guidelines, you can help ensure that your abrasive belts are safe and effective to use.
