For all those home improvement projects, woodwork or auto jobs, a ready supply of sandpaper is a tool box essential. From the toughest surface to the finest metal polish and glass-like surface, there is a piece of sandpaper specifically created to buff your project to a smooth finish.

But not all sandpaper is created equal – it’s a crowded market of abrasive types, grit sizes, hand or power tools, coarse or fine. And you need to make sure you get the right type for your DIY project – a rough grade won’t cut it for a car metal finish, and a fine grit sandpaper will make little difference to an old, wooden floor.

If you are confused by the choice, then now’s the time to (sand)dust yourself down and let us help you to become a smooth operator with our best sandpaper review.

Best Sandpaper Buying Guide & FAQ

What to Look for in a Sandpaper

Picking the best sandpaper for your DIY or auto job and knowing just how abrasive it needs to be are essential for getting the very best end results. We can help you decipher all the numbers and tech jargon on the packaging, so you know you are on the right sandpaper track:

  • Grit

You want sandpaper to do a specific job – whether that is to whip off paint or rust, smooth down a stripped bonnet or shape a piece of wood. To get the right result, you need to have true grit – and by this we mean the best rough surface. The best sandpaper is graded based on the number of abrasive particles per inch it has – the lower the number the coarser the sandpaper grit is. You now need to match the grit number to the particular job at hand.

As a guide, coarse sandpaper will come in at 40-60 grit (extra coarse is 24-36), medium rates between 80-120 and fine sandpaper is 150-180. Then there is very fine (220-240), extra fine (280-320) and even super fine (360 and above).

Choose coarser papers for removing paint and varnish or sanding old wooden floors; medium for general wood sanding and shaping; and fine paper for smoothing and fine-polishing the job. Extra fine grit sandpaper can also be used between coats of paint or varnish.

  • Grading

Sandpaper comes in two grades – commercial and industrial. The main differences are the material used for the grit, backing paper and the adhesive used to hold the grit onto the back. Industrial grades use higher quality materials for all three.

  • Open or close

The best sandpaper can also have either an ‘open coat’ or a ‘closed coat’. This shows the grouping of the grit particles – either open, which have larger gaps between the particles or closed, where the grit is grouped much more closely together. If you are looking to work wood, opt for an open-coat paper as it clogs less often so good for softer woods. Closed sandpaper is generally more durable and can be used on larger, tougher jobs.

Wood Turing Finishing

Types of Sandpaper

There are six main types of sandpaper with different levels of abrasive grit designed for different jobs, and not all are just meant for woodworking:

  • Glasspaper

Also known as flint paper, this is a lightweight paper that is typically a pale-yellow color. This type of fine sandpaper disintegrates easily and is best used for smoothing and polishing.

  • Garnet paper

Brownish-red in color, this sandpaper is most commonly used for woodworking. It is best for final sanding as it does not work the wood as fast as other papers but it does leave a better finish.

  • Emery paper

Emery works for both hand sanding and power sanding metal. Use coarser grits to remove rust or paint and finer grits to polish.

  • Aluminum oxide

Known as the ‘jack of all trades’ sandpaper, this works well with wood, paint, or metal. It is also used in electric power sanders as it is durable and hard working.

  • Silicon carbide

This dark gray sandpaper is used for finishing metals or for ‘wet sanding’ when you use water as a lubricant. It is extremely hard and not usually used for woodworking.

  • Ceramic

As one of the most durable abrasives, this is the speed monster of all the sandpapers and can whip through a considerable amount of material. Often used for belt sanders, it can also be used for hand shaping wood, although care needs to be taken as it can have a habit of leaving a rough finish.

How to Use Sandpaper

Once you have chosen the best sandpaper for your specific DIY or auto job, polishing up on your sanding technique will mean you get a smooth finish.  If you are sanding by hand, opt to use a sanding block, around which you can wrap your chosen sandpaper for a secure and stable grip. For a general sanding job, start off with a lower grit coarse sandpaper to remove those surface lumps and imperfections and apply enough pressure to keep the paper in place and moving smoothly.

If you are sanding wood, sand in the direction of the grain and not against it and move back and forth in a straight motion. Keep a sustained motion and pressure across the surface and don’t neglect the corners or edges. Wipe the surface clean of sanding dust and then repeat with your medium grit paper (or the appropriate paper for the job) before finishing with a finest-grade sandpaper grit for a final smooth. Wipe clean and check your handy work – if there are still lumps and bumps or paintwork present, repeat until you are totally happy.

Best Sandpaper FAQ:

Q: What is Sandpaper?

Sandpaper is a coated sheet of paper or cloth, which has abrasive ‘grit-like’ material glued to one side to create a rough surface. It doesn’t actually have sand as an abrasive – today’s sandpapers use alternative abrasives such as aluminum oxide or silicon carbide. They can also have natural grit such as emery or garnet. Sandpaper comes in a range of grit sizes for a host of different sanding jobs and is typically used to remove material such as paint or varnish or to smooth down and prepare a surface. They can also be used to make a surface rougher, for example when preparing for an adhesive. Q: What is the Meaning of Sandpaper Grit? Grit is the abrasive material that is glued to the surface of the sandpaper and provides a surface of varying coarseness that is used to polish, sand or strip a surface depending how hard and rough the grit is. A sandpaper’s rating is determined by its grit – which is the sharp particles glued to its surface – and the grit size – the number of particles per inch of sandpaper. The larger the grit size, the smoother the fine sandpaper and conversely, the smaller the grit size, the coarser the paper. Sandpaper grit can also be classed as ‘open’ by which there are more gaps between the particles and ‘closed’, which means there is less space. The more open-coat sandpaper works well with wood as it gathers the dust while closed paper is much more durable.

Q: What is 2000 Grit Sandpaper Used For?

Sandpaper with a 2000 grit rating is an ultra-fine sandpaper that can be used for a final sanding to achieve a smooth finish on a car’s paint or bodywork. It can also be used removing light clear coat scratches that can’t be removed by rubbing compound and buffing. 2000 grit sandpaper is best used wet when used for fine finishes as the lubrication helps to carry away any grit particles which could ruin the finish if they weren’t easily wept away. This means the 2000 grit sandpaper needs to be soaked before use; the best liquid to use is clean water with a small amount of detergent to lower the surface tension of the water for a smoother glide. In some cases, oil can also be used.

Our Top Pick

The well-priced 120 to 3000 assorted grit sandpaper pack is our top pick thanks to its combination of value, quality and variety. You get a useful range of 12 different grit sizes to take you from rough sanding to fine polishing. The paper quality also easily stands up to wet use for those delicate bodywork jobs.
