Sandblasting VS Soda Blasting: What Are The Differences Between Each?

Sandblasting VS Soda Blasting: What Are The Differences?

One of the most common procedures done in the DIY, Metalworking and woodworking areas is abrasive blasting, also known as sandblasting. This is a process where a surface is smoothed down or cleaned using a high pressure stream of abrasive material, like silica. However, recently I have had many people asking me of the difference between sandblasting and soda blasting. I have several years involved in this industry, so I’m qualified to answer the question.

What is the difference between sandblasting and soda blasting? The difference is that sodablasting is a milder form of blasting that uses baking soda as the abrasive material. Baking soda isn’t as abrasive as the traditional materials used in dry or wet sandblasting, such as sand, and that makes it the ideal choice for working on more delicate surfaces. 

Soda Blasting has several pros over sandblasting as you probably know, but it also has its disadvantages. The ideal blasting type will depend a lot on what type of surface are you trying to work on, how deep your pockets are, and other things. If you want to learn more about the pros & cons of both types of blasting, the other types of blasting available, and more, please check below!

Most Common Types Of Abrasive Blasting

If you are reading this article, there’s the probability that you are looking to blast a wall or a project that you have been creating. If this is the case, I think it’s important that we talk about the different types of abrasive blasting available. The choice that you make depends a lot on how harsh and rough do you need to blasting to be. Anyways, here’s the list.

  • Dry sandblasting: One of the harshest methods available, dry sandblasting works by propelling an abrasive material, typically silica sand to a surface. dry sandblasting is typically used for metal surfaces, removing rust, and any surface that does not need a softer type of blasting. Because of the danger associated with this type of blasting, it tends to be pretty expensive, and some locations require a special license for this type of blasting to be done. 
  • Wet sandblasting: Wet sandblasting is very similar to dry sandblasting, but the only difference is that water is added onto the abrasive mix. This helps with the lubrication of the surface being blasted, which helps minimize damage to it as much as possible. This method also has the added benefit of being cheaper and safer than dry sandblasting. It’s not as effective as dry sandblasting though. Just something to keep in mind.
  • Dry ice blasting: As the name implies, dry-ice blasting uses a pressurized air stream to blast solid carbon dioxide onto a surface. Unlike some of these methods, dry-ice blasting is technically not a method of blasting. This is because it’s non abrasive, and because of this, it’s used as an environmentally friendly way to clean up dirty surfaces. It’s also much easier to clean up. After the dry ice is blasted, it simply sublimates, and the only thing to pick up are the dislodged dirt particles.
  • Bead blasting: Also known as glass blasting, this is a blasting method that uses glass beads as the abrasive material to clean up a surface, typically one that requires more delicate treatment. It is also a popular way to treat metal surfaces and make them smoother. However other than this, this method is usually not used for cleaning up things like graffiti or rust because this method isn’t abrasive enough.
  • Water blasting: Like dry-ice blasting, this is technically not even a type of blasting per se, because abrasion isn’t even involved. In fact, this is just another term for high-pressure washing of a surface, typically graffiti and dirt. Waterblasting will only be useful if you are looking to clean up superficial dirt from a surface, but if you want to remove things like rust from a surface, then this method will not be enough.
  • Soda Blasting: A milder form of abrasive blasting, the main benefit of this when compared to dry and wet sandblasting is that this method isn’t as harsh as traditional sandblasting. This makes it a great choice for blasting delicate structures like sculptures and some types of painted walls. Also, a bit benefit of this is that it’s an environmentally friendly type of blasting. 

Pros & Cons Of Sandblasting

Since this is an article about sodablasting vs sandblasting, it’s important that you know a few pros & cons of each. I talked about that a little bit already, but this is a more comprehensive account of the advantages and disadvantages so that you can be more informed.

  • Sandblasting is harsher & more effective: As I have said above, sandblasting is the best choice if you are dealing with removing rust from a surface. Not only that, if you are looking to remove paint, or clean up machinery, then sandblasting is the right choice for you.
  • Sandblasting is more expensive: This is something that will depend a lot on where you live, but generally, dry sandblasting tends to be more expensive than sodablasting. As we mentioned above, there are some locations where you need a special permit to sandblast, and if this is the case with there you live, then it’s very likely that sandblasting will be really expensive.

Pros & Cons Of Sodablasting

Now that we talked about some of the pros & cons of sandblasting, it’s time to do the same with sodablasting. Again, this is by no means a full pros & cons list, but it contains the most relevant advantages and disadvantages though.

  • Sodablasting is significantly less abrasive: This might be a pro or a con depending on the surface that you want to work on. If you are looking to remove rust from a surface or clean up graffiti from a commercial building, then sodablasting is probably not going to be enough. Sodablasting is much more ideal for things like wooden cabinets and other things that require a type of blasting that is less harsh.
  • Soda blasting is environmentally friendly: This is another reason why you might want to use this method. It is much more environmentally sustainable than sandblasting, which tends to use environmentally unfriendly materials. This is also another reason why the government tends to use this method to clean up gum from the streets and sidewalks.

Is It Possible To Do The Sandblasting Yourself?

The answer is that yes! You can do the sandblasting yourself, and you can do this by either buying the gear or building it yourself. If you find that sandblasting/sodablasting is out of your budget, doing this will save you a lot of money.
