One of the most common issues we hear from inexperienced DIYers is that ‘my sanding belt keeps breaking’.
Sanding belts should last around 12-18 months if they’re used constantly. Though a hire company will check that your sander is in perfect working order for your before it leaves their warehouse.
If you notice that your sanding belt keeps breaking, it could be down to a number of things.
If your sanding belt keeps breaking, it could be down to a manufacturing defect. If the manufacturer hasn’t had the belt at the right temperature for the glue to set or tape to cure, then it may not be as strong as it should be.
The belt also needs to be scuffed properly prior to glueing to ensure strong adhesion. If this process wasn’t carried out correctly, your belt could be weaker than it should be.
If you notice this happen to belts from the same manufacturer, then it could be an issue with their quality assurance.
If you notice your belt popping off regularly, it could be because there is too much of the material that you’re sanding getting into the machine. If large particles get caught up in the machine it can put a lot of pressure on the belt. This will eventually wear it down and cause it to snap.
Storage is essential when it comes to keeping your belt in good condition. If the sander is stored where there is excessive moisture or condensation, or its exposure to extreme cold or heat, this can affect the pliability of the belt. This will cause it to become brittle and be prone to breaking or crumbling.
You Are Using The Incorrect Belt
There are several different types of belts and it’s essential that you find the right one to suit your needs. Paper backed belts provide a smoother finish than cloth backed belts but are much more delicate. If you’re sanding metal rather than wood, then a cloth backed belt will be required to prevent the belt from snapping.
You should also ensure that you’re using the right pressure for the type of belt you have. Putting excess pressure onto your belt can lead to tearing, folding or joint failure. Depending on the type of belt you’re using, this is the maximum pressure you should apply:
- Paper backing – 45-55 psi
- Cloth backing – 55-65 psi
- Polyester backing – 65-85 psi
