About this deal

It is also the common choice when sanding painted walls, smoothing out plaster and rubbing down filler to blend in with the surface it's on. This sits below coarse sandpaper and includes 24 and 36 grit sandpaper. It is used for jobs that have a lot of paint or varnish to remove. It's often used on rough timber that needs to be smoothed out and the first sanding when sanding floorboards. What does the P mean in sandpaper grits?

Extra-coarse (24-, 30- and 36-grit): Generally used for preliminary hardwood floor sanding, this usually comes in belts that fit on a drum sander, or disks that fit an edger. Very minor blemishes or small scratches in final coats can me smoothed out with super fine sandpaper. Grit Material 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. This ranges from120 to 220 grit and is one of the most commonly used grades in home DIY projects. Painting projects often use 120-180 grit for sanding down previously painted surfaces. It gets rid of any minor imperfections and roughs up the surface to provide good adhesion for a new coat of paint. It is also used on bare wood to smooth out ready for the first coat of paint or varnish.

The Grit grades below are a guide to the commonly found sandpapers available and thier uses. Manufacturers differ on the scale but this is the average. 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.

The Coated Abrasive Manufacturers Institute (CAMI) and the Federation of European Producers of Abrasives (FEPA) regulate sandpaper grit standards. They refer to the size and number of holes in the screens that filter the abrasive particles. Extra-fine (320- and 360-grit): The first of the micro-abrasives, this is primarily for sanding finishes before polishing.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. Fine (100- and 120-grit): The best utility sandpaper. Fine grades smooth scratches left by coarser grades and rough up painted surfaces before accepting new paint. They’re also good for sanding drywall. When you just need some for hand-sanding, or to use with an orbital sander, this is the grade you’ll most likely use. Grits above 320 such as 400 to 600 are typically used to get a really fine finish on wood ready for waxing or polishing. It can also be used to smooth out a top coat and fine wet sanding. Very-fine (150-, 180- and 220-grit): This produces ultra-smooth surfaces on wood. People often use it to scuff-sand lacquer, polyurethane and other finishes before applying another coat.
