Sand is a common sublayer for hardscape features like driveways, paver patios, and more. Most projects that involve sand require a 1-inch layer to promote evenness, drainage, and weight distribution. For further drainage, most projects have a 6-inch minimum layer of gravel beneath the sand. 

Sandblasting is a common method for removing paint. It works great if the underlying material is tough. This is because you can then use more abrasive sandblast materials, making the paint removal process much faster and less expensive. If you plan on removing many layers of paint on smooth surfaces, you’ll need to be more careful about which materials you choose to use to sandblast.

There are two ways sandblasting could be dangerous: improper use of the equipment so that the stream touches your skin, and air particles created during the sandblasting process. While the first is easier to avoid and fairly obvious, the second has the potential to be more serious and is much more difficult to understand. This is why you should always hire a pro to sandblast, as they understand the dangers associated with the process. If proper safety measures are taken, then sandblasting is rarely dangerous.

Because these two systems have different applications, there is no definitive answer to which is better. When working with sturdy materials, sandblasting is cheaper and faster, but more delicate projects require soda blasting. Before choosing either option, consider your specific needs, particularly your ultimate goal (cleaning, removing rust, prepping for painting, etc.), the material, and your budget.
