Types of Sand Blasting Commonly Used – Their Differences
There are two main types of sandblasting, wet and dry. Let’s take a more in-depth look at these two types of sandblasting to get a better idea which type you may require for your job.
- Wet sandblasting is mainly used for exterior, outside jobs. Wet sandblasting is preferable over dry sandblasting as it is often considered less invasive. Before wet sandblasting, ensure that you cover all structures in the surrounding vicinity that do not need the sandblasting process with thick plastic sheeting. This will ensure they stay protected from erosion while the sandblasting process is underway. Be courteous and notify your neighbors before you begin sandblasting. Your neighbors would most likely like to cover some of their property to ensure it doesn’t get covered in sand! Sand may drift towards a neighbor’s property. This can cause issues, ruin or destroy plants, affect wildlife in a negative way, and could lead to sand needlessly polluting the water table.
- Dry sandblasting is typically used on interior jobs or special projects. As you may have guessed, dry sandblasting does not use water in the process. Usually, dry sandblasting is not allowed except when special permission has been granted from the local council. Permission to perform dry sandblasting activities will only usually be granted where wet sandblasting cannot be done due to specific circumstances. For anyone applying for a permit to perform dry sandblasting, you will need to state in your application why wet sandblasting cannot be used. If you do not your permit may be denied.
