With such a vast range of abrasives to choose from, it can be easy to get a bit lost. Here's some reminders to help get the perfect abrasive every time!

Method of Sanding

Firstly consider which method of sanding you plan to use. If you have a power sander, make sure the discs you're looking at are the correct size and consider the number of holes for dust extraction you'd like, such as this 15-hole disc.  When using a ½ sheet sander, be sure to use an abrasive roll of an appropriate width and length, such as this roll which is available in a selection of grits and materials.  Alternatively, you may be sanding by hand using a sheet or roll. Again, you'll want to consider the length and number of extraction holes. You might even want waterproof for wet sanding applications, or you can use a sanding block which come in a variety of densities, such as hard/ soft and medium/ extra soft.

Materials

Once you have considered your method, next is the type of abrasive material appropriate for the job. Aluminium Oxide is the most commonly used material as it is tough and versatile, and perfect for smoothing wood, drywall, metal and metal welds, removing paint and removing rust.  Alternatively, waterproof silicone carbide can be used in wetting applications. This type of abrasive is typically available in fine or ultrafine and is best suited for smoothing wood finishes, plastic, glass, ceramic and nonferrous metal.  And consider zirconia alumina for industrial duty sanding, as this abrasive material is best suited to medium metal removal and weld smoothing.

It may be necessary to consider the material on the back of you abrasive too. Cloth backing is perfect for providing flexibility for shaping and contouring, while foam backing is a bit sturdier and gives better pressure distribution.

Grit Size

Finally, the grit size indicates the number of grit particles on the abrasive, the higher the number, the finer the results of the abrasive. A good guide is P60 and under is coarse and suitable for deep and coarse cutting, P80 – P100 is medium and suitable for sanding uneven surface, and anything over P120 is fine, with over P400 being super fine, and these grits are best for final surface treatment and creating a smooth surface.
