Both media blasting and soda blasting can help remove graffiti and clean surfaces, but there are certain pros and cons of using these techniques. You have to educate yourself about those factors to be able to decide between media blasting and soda blasting.
Media blasting is a less abrasive option as compared to sandblasting. It is much safer too. Sandblasting is still an effective option, but it may not be suitable for soft surfaces. Basically, both sandblasting and media blasting are the same techniques, but the use of different materials makes them suitable for different applications. The use of sand granules can leave scratches on different surfaces, but media blasting prevents this issue. The truth is that when sandblasting is done using materials like crushed glass, walnut shells, etc., it is called media blasting.
Basically, soda blasting uses the abrasive action of sodium bicarbonate couple with highly compressed air. It would not be wrong to suggest that soda blasting is actually a milder form of abrasive media blasting. It certainly has many benefits. For instance, it is an environmentally friendly option to clean different surfaces. It is much gentler as compared to sandblasting and produces less heat, which is why it will not pit or warp metal surfaces. You can also use soda blasting when dealing smoke fires, mainly because sodium bicarbonate can deodorizes smoke fires.
Soda blasting is certainly an environmentally friendly option, but the cost of machinery, chemicals, and labor is high. Therefore, you need to be ready to spend more, especially compared to what you would otherwise be spending on sandblasting. The good thing is that soda blasting is a relatively quicker to set up, which means that you will save a lot of time here. Moreover, you do not have to deal with overhead expenses that would hurt you when using harsher techniques on materials like plastic. It is important to note though that sodium bicarbonate shatters after use, which means that you can use it once only, and this can push the cost further up.
If you need to work with surfaces like aluminum, wood, or plastic, you should avoid all other techniques and stick with media blasting. Sandblasting is never a good choice for these materials. If you are looking for an improved way to remove graffiti and that too at an affordable price, you should look no further than media blasting.
The fact of the matter is that both media blasting and soda blasting can help you clean surfaces, but you have to consider your unique requirements and your budget constraints to choose between the two options. If you are dealing with softer surfaces, both media blasting and soda blasting with work just fine. However, you need to bear in mind that soda blasting is going to prove a lot more expensive than sandblasting or even media blasting. Therefore, some information about your budget matters a lot, and it is equally important to ensure that you have hired a true professional to get the best value for your money.
