If you want to enjoy a successful project, the right sanding disc is the one you should use. The job will be done faster and easier if the right sanding disc is used. If you use the wrong sanding disc on some surfaces such as soft plastic and metal, you might cause permanent damage to them. An abrasive material and a piece of disc backing are the two things that are bonded together to make sanding disc. Sanding discs come in different forms. A heavier backing is used on sanding discs that are used with power tools. But those that will be used with hands do not have such features.
The backing is the material that is used to hold the grit. Sanding discs have different types of backing, and because of that reason, the qualities of them are different. The most common backing material that is used in sanding discs is the abrasive material. If you want to use the sanding disc on a large, flat surface or with a power tool, you should look for one that has a stiff disc backing. If you want to use the sanding disc on wet or dry surfaces, you can choose the one that has a waterproof backing. When a lubricant is used or when wet sanding, the abrasive material will be kept attached to the backing by the waterproof adhesive.
Those sanding discs that are highly flexible are made with cloth backing. If you want to use the sanding disc on highly contoured or detailed surfaces, you should choose one that has cloth backed sanding disc. Grit is the term used to describe the level of abrasiveness of sanding disc. The backing of the sanding disc is used to indicate the grade of the grit. However, there is a formula that is used to scale the grit of sanding discs, even if it is indicated on the backing. If you want to sand a soft surface, you should look for sanding discs that have been graded above six hundred grits.
Finely crushed minerals are the materials that are used to make the abrasive of sanding discs. Because of that reason, before you buy sanding discs, you should check the materials used to make them. Surfaces that need sanding are different, and that’s why different materials are used to make the abrasive of the sanding discs. If you want to sand a painted surface, you should buy sanding discs made with glass grit. The most common abrasive for sanding disc is the garnet grit. In many cases, it comes with a red color. This type of grit is common because it can be used to sand different materials. If you want to sand metallic surfaces with power tools, you should buy aluminum oxide grit sanding disc. It is the best option for such surfaces because it lasts a bit longer. When purchasing one, you need to consider the price because nowadays the dealers are too many due to the high demand in the market.
