Sanding and pressure washing are both effective ways of maintaining your deck, but one method isn’t necessarily better than the other. Instead, they have different purposes and benefits. Pressure washing cleans dirt and grime off a deck and should be done every year. Sanding removes the old finish and prepares a deck for staining or sealing. This should be done every one to two years.

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.

The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.

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.
