Sanding and pressure washing serve different purposes in deck maintenance, so one is not necessarily better than the other. Pressure washing is ideal for annual cleaning to remove dirt, grime, mold, and mildew. Sanding is a deeper restoration method used to smooth rough surfaces, remove an old finish, and prepare the wood for a new coat of stain or paint. The ideal process for refinishing a deck is to first clean it (with a power washer), then sand it, and finally apply the new stain or finish. While cleaning should be done annually, sanding and staining are typically needed only every one to three 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.
