Traditionally, sandblasting was carried out using only sand, but now, in the 21st century, the power and flexibility of this kind of abrasive technique means that sandblasting abrasives have been developed and now a variety of different materials can be used depending on the job that needs to be done. There are lighter abrasives such as walnut husks through to glass beads for really heavy duty tasks, and thanks to this range of different materials being available to you, it is possible to get a much better result every time.

While sifted sand was traditionally used as the main sandblasting abrasive, it has recently fallen out of favor for a number of reasons. The main one is that the dust that is released when conventional silica sand is blasted onto a surface can be toxic and cause a lung condition called Silicosis. This disadvantage of sand as a sandblasting abrasive means that whenever it is used, extensive protective clothing must be worn, and other precautions such as masks and breathing gear are essential.

By using less harsh sandblasting abrasives, you can get a much more subtle effect from your work, have more control over the finish that you get, and also ensure that you do a lot less damage to any underlying materials when you are using the sandblaster. Using a material such as glass beads and a lower air pressure also provides an extremely gentle cleaning action that is popularly called bead blasting.

There are also very highly abrasive materials available, which offer an even more powerful effect, and are ideally suited to much heavier jobs such as removing very thick paint and layers of material from surfaces. These rougher sandblasting abrasives such as Black Silicon Carbide are extremely hard crystals that are robust enough to strip material from a surface and leave it clean and ready for either painting or other treatment.

Blasting Garnet is one of the most powerful abrasives available. Offering the same kind of robustness as silica, without the same health risks, blasting garnet is one of the best options that is available to users in terms of the quality it can offer and the power with which it can cut through unwanted coatings and give users a good quality finish.

The main requirement for any sandblasting abrasive is that it is a very hard material. Aluminum oxide is just such a material, and is widely used around the world. It offers a number of benefits, but one of the main ones is the relatively low weight of the individual grains. This allows for higher speeds to be achieved, and en even more powerful effect to be possible.

For really fine finishes such as those required with more precise jobs and for decorative work, black walnut shells are the perfect solution. Although much softer than mineral grit, thanks to their light weight, they are extraordinarily effective at removing surface materials.

The key to getting the best possible results is to use properly sifted sandblasting abrasives, no matter what materials you use. It is vitally important to use grains that are the same size, as this will ensure that you are able to get the most even and uniform finish possible. With professionally prepared abrasive materials, you can be sure that you will get high quality products that are ready to use.

Sandblasting abrasives such as blasting garnet or black silicon carbide are extremely tough and robust and give you excellent results very quickly. Without the health risks of traditional sand they provide a safe and effective alternative to traditional materials, and are widely accepted to be the ideal solution to the needs of anyone who wants to be able to get the most effective solution possible.
