Aluminum oxide – Suitable for a range of surfaces including wood, plastic, metal, and drywall.The result is a gradual reduction in the abrasiveness of the sandpaper which makes it ideal for finishing work but does have the disadvantage of reduced durability. Garnet has a unique quality in that the particles will fracture during use. Garnet – A group of natural, silicate minerals ideally suited to woodworking projects.We have listed the most common materials below. There are many different materials that can be used for this purpose, depending on the intended use of the sandpaper. These abrasive particles effectively scrape away at the surface to which the sandpaper is being applied. In order for sandpaper to be effective, it needs an abrasive material, in the form of tiny particles, securely attached to the backing paper. Although less common, it is an ideal backing material for cases where greater control and flexibility of movement are needed, which is often the case with intricate sanding work. A good example of this would be in the case of wet and dry sandpaper, designed for use in conjunction with water.Ĭloth is also used as a backing material in some sandpapers. When the sandpaper has been designed for use with lubricant, a waterproof paper would be used in place of the standard backing material. The quality of paper used will vary for example, if the sandpaper has been produced for use with powered tools, such as the random orbital sander, it is generally higher in quality. The most common material used is paper due to its relatively low cost of production but also its versatility. There are different types of backing material used for sandpaper depending on its use. There are several components that make up sandpaper including the backing material, the abrasive coating, and the adhesive used to secure both of these together. At best, this will make the work a lot harder than it needs to be and, at worst, could ruin the surface that you are sanding.Īlthough choosing the correct sandpaper may seem like a daunting task, it does not have to be and with the help of this guide, you can be fully informed on the various attributes of sandpaper, allowing you to make an informed decision on what type you need to purchase for your project. There are also different standards for the size of the particles that make up the grit component of the sandpaper, and there are different levels of coverage.Īll of these factors require careful consideration because using the wrong type of sandpaper will impact the sanding process. Sandpaper comes in many different forms not only are there various backing materials and abrasive particles, but there are also multiple shapes of sandpaper for use with specific tools. Table of Contentsġ – Why choosing the correct sandpaper is importantģ.1 – Coated Abrasive Manufacturers Institute (CAMI)ģ.2 – Federation of European Producers of Abrasives (FEPA)ħ – FAQ Why is choosing the correct sandpaper important? ![]() ![]() Regardless of the exact makeup, the requirement remains roughly the same to effectively remove imperfections and prepare a surface for finishing while minimizing the required effort. While sandpaper is no longer made using grains of sand, the name has stuck and is now what we use to refer to a range of different backing materials covered in various types of abrasive particles. In the united states, sandpaper was not commonplace until 1935, when sandpaper was patented by Isaac Fischer, Jr., of Springfield, Vermont. The name itself dates back to 13 th century China where sand (Along with crushed shells and seeds) was bonded to paper using natural gum. For this reason, we decided to take a deep dive into the different types of sandpaper grit available and the grits required for each type of sanding task. Even the best orbital sanders rely on having the correct sandpaper grit in order to perform at their best. Although sandpaper has a wide range of applications, it is most typically used to prepare surfaces for painting, varnishing, or otherwise finishing. Sandpaper, the friendly name for a coated abrasive, is used by DIY enthusiasts and professional tradespeople alike.
