The disadvantages of sandblasting are noise, mess, and risk. Sandblasters are louder than chainsaws and spread debris on the ground and through the air. Let your neighbors know that you're sandblasting so they can prepare. Sandblasting can damage your property if not done properly, so thoroughly vet any pros you talk to before hiring.

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.

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.
