Best sandblasting pros near Union Hall, VA

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. 

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.

Sandblasting refers to the process of cleaning a surface using compressed air and aggregate. Soda blasting is the gentlest type of this method, but it differs from sandblasting that uses mineral or other aggregate, since sodium bicarbonate breaks apart more easily than other forms of blast media and, therefore, cannot be reused.

Soda-blasting systems are slightly more expensive than sandblasting systems. To soda blast, you’ll need to spend a few hundred dollars for a blast hose and nozzle, a compressed air supply, a blast generator, a moisture decontamination system, and sodium bicarbonate media, a recurring cost because the powder is not reusable. To start with sandblasting, you will need to spend upwards of $30 for a blast pot, a blast gun, an air compressor, and sandblasting media, many of which are recyclable—further reducing the cost. The total cost for either will depend on the size of the system.
