However, if you are unsure which one to use to obtain the results you want, the overview below can help you. 1. Coarse Sandpaper: #60–#80 Grit 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 Considerations As we have seen above, it is crucial to find the right type of sandpaper for your project. The indications above are an excellent starting point to find good sandpaper grit for your job. Also Available at: Walmart , Auto Zone 3. Best Coarse Sandpaper for Sanding Wood—3M 9017 Coarse Grit Sandpaper

Coarse grits are good for bare wood, removing paint and deep scratches. However, do keep in mind that this specific paper is to be used only manually or with a finishing sander. This is a commonly used grade in a lot of home DIY projects, especially painting projects such as painting skirting boards, windows and doors. 120-180 grit is ideal for sanding down previously painted surfaces that don't need a lot of work. Sandpaper grits are categorized by how coarse the abrasive material is. You will ideally start with a coarser abrasive and use progressively finer ones to achieve a smooth result. The most common grits are 60-80 (extremely coarse), 100-150 (medium grit), 180-220 (fine), and 320 (ultra-fine). As such, we are often faced with the following dilemma: should I choose a coarser or finer grade for my particular application? The answer can be just as difficult to determine as deciding which type and brand of sandpaper to use in the first place! Below are some points for consideration: 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 this type of sandpaper can be potent, it also needs to be used appropriately. Indeed, it is easy to damage more delicate surfaces and layered materials such as veneer plywood with coarse sandpaper. 2. Medium Grit Sandpaper: #100–#150 Grit

The “P” in front of the second number indicates it refers to the FEPA scale rather than the CAMI one.Abrasive particles come in many sizes and shapes, with the most common particle shape being round. The smaller the particle is that makes up an abrasive, the rougher it will be on a surface because there are more edges to each particle as its size decreases. Sandpaper grit numbers express how many thousandths of an inch wide (called microns) one side of a piece of sandpaper is. For example, 400 grit is about .4mm (4000 micron) wide per side and 8000 grit is about .08mm (.008mm per side). For most DIY sanding projects you will need 60-240 grit sandpaper (Image credit: Steven Jenkins) Should I sand by hand or use a power sander? For example, you might find indications such as “suitable for metals, painted surfaces, wood, and plastic” or “general purpose.”

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. 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.

What Does the P Stand for on Sandpaper?

Grit describes the sandpaper's abrasiveness and whether it is fine or coarse. A larger grit number indicates finer sandpaper, which is ideal for producing a smooth surface. Sandpaper with a lower grit number is coarser and rougher, so if you merely need to swiftly scrape dirt, and other things off of a flat surface, a scrubbing pad with a coarse grit is your best bet. Because coarse and fine sandpaper grits are used differently, manufacturers established grades — each consisting of one or more grit numbers — to help consumers decide which type fits a particular purpose. The coarsest grade, designated as extra-coarse, includes 24-, 30- and 36-grit paper. The finest grade (i.e. ultra-fine) includes 800- and 1,000-grit paper. Here's the different sandpaper grades and grits to help you choose the right one for your DIY project:

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. To choose the correct sandpaper grit, you need to start by understanding what grit is and its impact on your project. Grit measures sandpaper’s coarseness, determined by the size of the abrasive particles on its surface. The higher the number, the smoother or finer that layer becomes on your surface. A fine tune to really make something shine - like a mirror finish- will use a very fine grit like 1500 or 2000 for example. The lower the number, the rougher the surface becomes when sanded. It comes with a company guarantee that it will not discolor any surfaces you are using it on. One of the many satisfied customers commented that it “works well, doesn't clog much, lasts forever compared to budget papers. So worth the extra money, as it goes 20 times longer than the cheap stuff.”While it’s possible to connect a dust extractor to most orbital sanders, the fact remains that sanding still creates dust. And even if you’re wearing the correct masks, tiny particles can still float around in the air, which could pose health risks – and even if they don’t, you’ll still be spending more time cleaning down surfaces once you’ve finished your project. Depending on the grit, a particular type of sandpaper might be suitable for removing paint and not smooth out bare wood – and vice-versa. Here is how grit works and how to select the right one.
