20 x 220 Grit Dry Sandpaper 23 x 28cm Sheets SandingPaper

Product Information

Large particles fit through larger holes. Because they’re larger, a standard filtering screen requires fewer of them. Consequently, coarser grits are known by smaller numbers than finer grits, much like larger-diameter wires have smaller gauge numbers in the American Wire Gauge system. Thanks to its high versatility, you can use it to round edges and corners or apply the finishing touches to your piece.

Ceramic sandpaper: This synthetic, reddish-colored option is the right sandpaper for rough sanding, sanding discs, and removing deep sanding marks from raw wood. Medium (80-grit): This is often the first grade chosen when going through the grits to prepare wood for finishing. Use it to hand sand, or with a belt or orbital sander. It’s also good for removing rust and corrosion from metal.Aside from not wasting labor, overworking a particular area might cause it to look blotchy or shiny. It can be challenging to reverse the damage and give your surface a uniform appearance. Steel wool: Made of fine flexible steel strands, this version falls into the finer grits category and is used primarily in between paint coats to prepare a smoother surface for the next coat.

When choosing sandpaper, it’s important to select the right grade for the job. A paper that’s too coarse will leave the surface scratched and damaged, while one that’s too fine won’t do the job. Extra-coarse and ultra-fine grades are generally reserved for rough sanding and polishing. A medium or fine grade works best for most projects around the house.

If you are looking for more coarse sandpaper to create rounded edges or remove old paint from a surface, go with smaller numbers. As we have seen, the number on your sandpaper refers to its grit. While this is an excellent indicator of whether the sandpaper is suitable for your project, it is not the only aspect to consider. To choose the correct sandpaper grit, you need to start by understanding what grit is and its impact on your project.

For example, sandpaper marked with the number 800 in the CAMI standards will correspond to a FEPA’ P2000 or P1500. The sandpaper grit numbers are a system of measurement for the coarseness or fineness of the abrasive paper. It is measured by counting how many lines per inch (LPI) can be felt with one square inch of the sandpaper sheet. They range from 30 to 2500, so there's something for everyone! The higher the number, typically means that it will cut faster and last longer - but not always. For instance, if you're using a coarse sandpaper on wood then a lower grit might work better because it won't take off too much of your material when you go over an area. So don't just assume because it's more expensive that it'll do everything you need in one pass! Aluminum oxide sandpaper: Synthetic in nature, this type is great for manual and orbital sander use and offers an extended lifespan as its edges wrinkle just enough to expose new abrasive material. Very minor blemishes or small scratches in final coats can me smoothed out with super fine sandpaper. Grit Material The abrasive grains used in sandpaper, nowadays—contrary to common belief—are not actually sand. Natural abrasive materials, like garnet, and synthetic abrasives like aluminum oxide have mostly replaced sand, and they provide a superior performance offering a variety of sandpaper grit options. Sandpaper ConsiderationsOther applications include removing old paint and making a surface rougher (such as in preparing it for gluing). Finer Sandpaper Coarse sandpaper has the lowest numbers. The abrasive material is made of bigger particles designed to cut through most materials. Sandpaper is an inexpensive, versatile piece of equipment with a long shelf life, so keeping one—or a set—in your toolbox is a must. The right sandpaper can come in handy for when you need a smooth finish, to remove paint, or for sanding wood. Even though they all may all appear to be the same, different sandpaper grit grades and materials should be used for different sanding projects.

The coarsest sandpaper is used for the fast removal of paint and rust. It is not the kind of paper you want to use on fine underlying surfaces, like a hardwood floor or linoleum. The abrasives embedded in this type of paper are so aggressive that they can remove portions of the layer you're sanding away, leaving stains. While it’s theoretically possible to manufacture sandpaper grits in tiny progressions, it would be impractical and confuse customers. Consequently, grit numbers increase by standard intervals. The higher the number, the finer the grit. Coarse grits progress from 24 to 30 to 36, while fine ones rise from 600 to 800 to 1,000 and beyond. This depends on the state of the wood you are sanding but as a general rule you should start out with a coarse grade sandpaper before progressing to a fine grade sandpaper to finish. This helps sand out any marks left by the larger grits. Sandpaper grit represents the size rating of abrasive materials that sandpaper is made of. Sandpaper grit is divided into different categories based on the size of the abrasive particles. The larger the abrasive particles, the coarser the sandpaper. Conversely, smaller abrasive particles make finer sandpaper. Super-fine (400-, 500- and 600-grit): Use this for polishing finishes on wood and metal, and to polish bare metal. It comes on waterproof sheets to allow for wet-sanding.While fine sandpaper with a higher grit is a must-have in any toolbox, it should only be used after you have already worked the surface with other tools or with a coarser grit of sandpaper. Other applications include making a surface rougher. You might need to do so when gluing two surfaces together.
