Sandblasting is an extremely effective way to remove rust. At the same time, it is a messy process and can damage the underlying metal if improper techniques or media are used. Fortunately, removing rust with a sandblaster is simple with an understanding of the process.

Rust removal requires:

• An air compressor suitable for the size of the project

• A portable blaster with piping, combo valve, and moisture separator

• A nozzle and blaster trigger

• Protective equipment for the hands and face

Generally, high pressure air passes by a port which contains a pickup tube. The vacuum pressure draws the sand (or other media) into the sandblaster gun and sprays it out through the nozzle. The high speed of the sand (or other media) acts like sandpaper particles and quickly removes rust.

As an alternative to sandblasting, media blasting is the use of an abrasive other than sand. Media alternatives can be beneficial depending on the type of job, as they can be more environmentally friendly, less messy, and less abrasive.

Types of media include:

• Soda

• Beads

• Aluminum Oxide

• Walnut Shells

• Corn Meal

• Ice

• Dry Ice

When sand (or other media) strikes the rusted metal, it scrapes off the rust particles. The nozzle should be held at an angle rather than directly pointed at the rusted surface. Rust forms unevenly so angling the nozzle gets under the rust to quickly wear it away.

Sand can warp metal with prolonged exposure because as the sand particles strike the metal, the friction creates heat. Warped metal is usually only noticed once sandblasting is complete, which is too late. To avoid warping, constantly move the nozzle over more surface area so no one area is blasted for more than a few seconds.
