On the other hand, using sandpaper with too fine a grit will result in a laborious, time-consuming effort to achieve your desired effect. If you use sandpaper that is too coarse, you risk irreparably damaging the surface of your material, resulting in an abrasive surface that you will not be able to smoothly polish or paint – and something which may be costly to repair or replace. Generally, when you are preparing any surface for painting, using the aforementioned method of ‘going through the grits’ to reach your end goal usually works – but it’s not always that simple. In order to correctly use sandpaper, it is essential that you understand the importance of selecting the right grit for the material you intend to work on. How to choose the right sandpaper for the material (and desired effect) Take a look at this handy table that simplifies the importance of grit numbers, and their appropriate material uses, to ensure that you are using the correct sandpaper in your project. Coarse grits progress from 24 to 30 to 36, while fine grits rise in increments from 600 to 800 to 1,000 and beyond, for example. In simple terms, a higher grit number correlates with a finer grit, and vice versa. ![]() When it comes to grit numbers, they are categorised into grades, and increase in easy-to-understand standard intervals, so as not to confuse the customer. With a wide range of grits available, it is important that anyone undertaking a new sanding project has a good understanding of grit size when it comes to effective sanding – which can often mean the difference between an unattractive rough surface and smooth, rounded edges. In other words, simply using only coarse sandpaper isn’t necessarily going to get the job done to the highest standard, and can indeed cause major problems. The level of coarseness you will be using will depend entirely on the type of surface and material you are working with.Ĭoarser grits are an effective way to wear down whatever surface you are sanding more quickly, but can leave minor imperfections (or even deep scratches) in the material, which are then removed by sanding down with finer grits – this is what we call in the industry, ‘going through the grits’. So, what exactly is sandpaper grit? Put simply, t he grit number determines the coarseness of the sandpaper, which is defined by the size of the abrasive grains on the surface. What is sandpaper grit and how does it affect the usage?
