Sand Blasting - Derrick Company

A Sandblasting Media for Every Situation Anyone working in the metal industry knows that abrasive sandblasting is the best way to smooth the surfaces of their materials. Yet having metal sandblasted isn’t as simple as many may think. If you happen to choose the wrong service provider, you could end up causing extensive damage to your parts. Luckily, providers who know the different intricacies of this process, like us here at Derrick Company, know how to help you get your parts prepped without leaving any signs of damage. One of the questions that we often get is which type of media is right for a particular job. Well, the answer to that question depends on a couple of different factors:

  • The sturdiness of the material being blasted
  • The difficulty in removing the paint, rust, or other materials being treated.
Some Things to Consider With that in mind, here are some tips to consider when choosing your sandblasting media:
  1. Start with gentler materials if you’re unsure. You can always re-treat the surface with tougher materials later. Aluminum oxide may be a good option here, as it is composed of very small grains ad typically delivers long lasting results.
  2. Glass beads provide a slick surface and are ideal for cleaning calcium build-up on tiles and fiberglass, or to remove dust and mold.
  3. Coal slag is best at removing paints and other types of coating in preparation for repainting.
  4. Steel shot is best for special finishes, as paint typically adheres to surfaces treated with this media better than with your other options.
  5. Don’t be afraid to ask for a custom media. There are a number of different biodegradable materials out there used to sandblast surfaces, including walnut shells, corn cobs, and baking soda.
Choose the wrong sandblasting media, and you could end up with irreparable scratches and even dents on your metal parts. Knowing which media are available to you and which will best suit the materials that you want treated will help ensure your happiness with the finished product.
