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

Product Information

Ceramic alumina lasts longer than aluminium oxide, and is considered to provide cooler sanding. It’s best suited to sanding metal.

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. 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. 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.” 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 fine grade of sandpaper is designed specifically to smooth out soft finishes like paint and varnish. It's ideal for tasks where you want the surface to look as polished as possible, with no scratches or marks visible. In terms of quality, it doesn't get any better than this type of paper. The abrasives are extremely refined so that they remove only minute portions of the layer you're sanding away – rather than big bits like their coarse counterparts – leaving stunning results behind.On coarse sandpaper, the abrasive material is present in large particles that are able to cut through the toughest surfaces.

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! 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 “P” in front of the second number indicates it refers to the FEPA scale rather than the CAMI one. Other applications include removing old paint and making a surface rougher (such as in preparing it for gluing). Finer Sandpaper 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).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.
