Sandpaper – Grits, Types and Uses

sandpaper uses and tips from Eve of ReductionHi Reduction Rebels! I have an interesting guest post today. As you know, I don’t accept a lot of guest posts but this one happened to catch my eye. When I started out as a DIYer, I often skipped the sanding step. Was I being cheap? Maybe. But the real issue was I didn’t see the value in it – until I was done with the project, of course. So here’s the 411 on sandpaper to help you with your next project.

TheRules of Working with Sandpaper

Sandpaper is used for scratching the imperfections on different hard surface. To learn how to use it and achieve the results you want, there are some rules you need to follow. Here are some tips and ideas how to use sandpaper for various home improvements. Different sizes of sandpaper can help you achieve different results. So you need to be careful before starting to work with sandpaper and learn more about it.

The main rule when working with sandpaper is first use coarse sandpaper to scrape all visible defects and roughness and then continue with finer sandpaper. You can use sandpaper before covering a wooden object with paint, for example. Start with 80-grit sandpaper and continue with 100, 120, 150, 180 until you reach 220-grit sandpaper. Usually most sandpapers with rougher grit have smaller number. Make sure you don’t skip any size of sandpaper between the smallest and the biggest size, as the results will show it.

Different Types of Sandpaper

Sandpaper is used attached to the hand like a glove or wrapped over a hard wood, which is used to scrape together with the sandpaper. Different sandpapers are appropriate for different tasks. Sandpapers are made of aluminum oxide, ceramic and silicon carbide.

There are six most often used types of sandpaper: natural, which can be garnet and emery, man-made, which can be silicon carbide, aluminum oxide, ceramic and alumina zirconia. To do successful and qualitative work you have to know with what grit to start sanding and with what size to finish the sanding. It’s also important not to skip the middle grits of sandpaper. Starting with a coarser sandpaper, you can make damages and scars in the surface you need to scrape. On the other hand, starting with too fine sandpaper, you can loose a lot of time and sandpaper, doing the job you want done.

American vs. European Sandpaper

To distinguish different sandpapers, you can read the number on it, showing its size. The European standards differ from American. A “P” letter in front of the number of the sandpaper, indicates a European standard of the size.

Sanding screen is used for clog-free polishing of joint compound. Sanding belt quickly removes stock. Flexible sanding sponge is appropriate for contoured surfaces. Sanding disc is usually used for making even all flat surfaces. Cloth-backed wet-or-dry sheets of sandpaper are used for making smooth and clear finishings with the use of water as a lubricating film. Paper-backed sheets of sandpaper are suitable for sanding all kinds of woods.

How to Know What Sandpaper is Right for Your Project

Garnet sandpaper is used for sanding untreated wood, but it loses its glamour quickly. Emery is perfect for polishing and sanding different types of metal, but it is too soft for other purposes. Silicon carbide sandpapers are extraordinarily hard. Although they can cut glass, their use is mainly for polishing up joint compound and eliminating the dust between the layers of finish. Aluminum oxide sandpaper is appropriate for power or hand sanding on paint, wood and metal surfaces. Ceramic sandpaper is harder, more enduring and pricey than the rest types of sandpaper. It can be applied on discs and belts for powerful sanding. Alumina zirconia sandpaper is used on machines for sanding.

Sandpaper can be used for sanding down car paint. If you want to remove your old paint from the car and repaint it, you need to choose the proper sizes of sanding grits to do this well.

There are plenty of tasks, which can be succeeded with the proper knowledge for using sandpaper and the necessary skills. Sandpaper is used for polishing and sanding defects, scraping the final layers of different surfaces, before applying paint or another coverings. It is a useful tool for doing some improvements in your home.
