Regardless of whether you are looking to remove an old finish from an item or if you want to blast rust or corrosion from the surface of an object or whether you need to prepare a particular surface for painting later on, you can use the technique of abrasive blasting. Indeed, this process is complex to understand while it uses specific machines to shoot a particular medium at a high-pressure across any surface. You may be daunted by the various choices which are available on the market but do not worry because expert advice is easy to find. However, you could also follow these simple tips which can help you decide on which blasting medium you should use for the task at hand.

Choose a soft blasting medium

If you are unsure about which blasting medium to use for sandblasting a particular surface, then you should probably begin with a very soft medium instead of choosing a more abrasive substance for the blasting process. Indeed, some of the softer forms of material that are used in the abrasive blasting process are corn or walnut shells. Furthermore, these forms of material are much softer than sand and will not cause lasting damage to the surface being blasted. Finally, these two types of medium are both environmentally friendly as they are biodegradable which means there is no polluting waste material produced from this process.

Looking for a shiny finish

If you want a smooth yet bright finish on whatever surface you need cleaning, you should probably opt to use glass beads as the blasting medium for this particular process. This relatively soft substance is generally made from small glass beads containing sodium or lime which are also very soft blasting materials while these substances do not stress the surface that you are blasting. Again, this particular blasting medium is recyclable meaning that no excess waste is produced during this process. If you want more information about blasting mediums then search for a sandblaster in Perth for advice. Therefore using this substance for abrasive blasting can help to reduce the environmental footprint of this process.

Use aluminium oxide

If you need to blast a slightly tougher surface then maybe you should choose a medium of aluminium oxide, which is slightly sharper and indeed much harder than the previously mentioned blasting mediums, including glass beads. Aluminium oxide is particularly cost-effective and efficient at removing paint from a surface while it can also be used for the process of etching on a glass item.

Plastic or silicon

Furthermore, you could also use plastic or silicon as a blasting material. However, these substances have very different uses and very different results. Plastic is a relatively soft material making it ideal for removing old paint from a surface, especially on fibreglass. In addition, the blasting medium of silicon provides the most aggressive type of cutting which can be used on very dense surfaces including stone or metal while it is particularly effective at removing corrosion, including rust. If you want to make sure you use the best substance for blasting a particular surface, then you should avoid using sand as this can cause significant respiratory problems for employees who work in the abrasive blasting process while it can also cause damage to the blasting equipment that is used for the job.

Make sure you choose the correct form of blasting medium to make sure you get the finish you want.
