Sandblasting takes place when a certain medium is blasted at super-fast speeds through a machine towards a hard surface. Sandblasting is used for things like smoothing out a surface for sanding, clearing a surface of dirt and rust or to take the finish off of an item. When you're sandblasting, you need to choose the sandblast media that works with your type of project. The media you end up using will depend on how tough the surface is that you're sandblasting.
If you're not sure what media to use, start with a medium one. If you choose media like walnut shells or corncob, you'll get a medium-level sandblast effect that's also biodegradable. If you need a really soft medium, try pumice stone, the softest of all sandblast media.
If you're looking for a smooth and glossy finish, use glass beads as a medium. You can also recycle them up to 30 times. If you need to do automotive sandblasting, use plastic beads made out of materials like urea, acrylic and polyester. They're great at stripping surface coats without damaging the metal or other materials underneath. If you need a really tough medium, use silicon carbide. It's perfect for the toughest and most difficult stripping jobs.
