Three Wrongful Beliefs About Sandblasting

Surface preparation by sandblastingIf you are thinking of buying a car or already own one, then you are going to hear a lot of things about sandblasting, especially when considering about revamping the vehicle.

Not all information you hear, however, is necessarily correct. Given that the decision you make will depend on what you learn about sandblasting, it is essential to get these three myths out of the way.

Myth #1: Sandblasting involves the use of sand

It is important to get one thing right about the term “sandblasting.” While the name implies that the sandblaster in NZ involves sand in the sandblasting process, nothing can be further from the truth.

Nowadays, sandblasting no longer uses sand as a result of health concerns. Rather, the process uses aluminium oxide, steel grit, and crushed walnut shells as abrasion materials.

Myth #2: There is such a thing as dust-free blasting

Some manufacturers will do anything to get you to buy their sandblasting equipment, including promising that their machines are entirely dustless.

Do not fall for that lie. Every standard abrasive tool will always produce some dust if it is working under normal conditions. Even the most effective vapour abrasive equipment can only suppress up to 92 % of the dust produced during dry sandblasting.

Myth #3: Blasting a large surface is more expensive

While the cost of sandblasting will depend on the size of the job, it does not mean that blasting a large surface is necessarily more expensive than a smaller one.

Actually, when compared with blasting on large surfaces, smaller jobs tend to be more costly due to the time they take for setting up and cleaning. This cost gets sucked up into the total cost when doing a larger job.

Sandblasting is an important step when preparing your car for a paint job. By having the right information about this process, you can dispel any doubts you might have had about its effectiveness.
