DIY is possible, but professional services ensure even removal, safety compliance, and proper cleanup.

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.

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.

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.
