Sandblasting Services FAQs, answered by experts

You can concrete can be done when it’s wet or dry. However, it’s safer when wet, as harmful dust and chemicals are present. Sanding it when dry is faster, but you’ll agitate more dust and chemicals, meaning you’ll need to be more careful.

Regular sealing and repainting help maintain the restored surface’s durability.

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.

If you’re DIYing the project, it could take up to a week if you aren’t able to dedicate full-time hours. If you hire a professional and they arrive with a team, expect your stairs to be sanded in as little as 2 hours (for simple projects). Finishing the stairs takes a while longer as there are drying and sealing times to consider, but the actual work will take much less time than the sanding portion.

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