Soda Blasting

What is Soda Blasting?

One of the quickest and easiest ways to strip your car of the old paint is by soda blasting. Soda blasting is a process that uses sodium bicarbonate (similar to baking soda, but formulated especially for blasting) applied to a surface using compressed air.

Earlier techniques used for removing paint or unsightly material from a contaminated surface were scraping, chipping, sanding, or using harsh chemicals. These methods required too much work, and results were not impressive. Now soda blasting has replaced these methods. Though soda blasting is similar to sandblasting, soda does not harm the surface nor the environment, during or after use.

Soda blasting is a process that can strip almost any surface in an efficient and safe manner. Soda blasting can easily remove carbon, grease, oils, gasket material, surface corrosion, paint and coatings from a variety of alloys, plastics and composites. It doesn't cause the damage to the base surface, or the distortion to metal panels, that you'd see with traditional media blasting. Soda blasting leaves hard anodized coatings intact.

Blasting with soda is the latest, "greenest" technology for safely stripping paint and/or cleaning nearly any surface. Soda blasting machines use compressed air to deliver soda onto the surface to be cleaned. Similar in concept to sandblasting, soda blasting is much kinder and gentler to the underlying surface and the environment. The process is gentle enough to remove the coating without harming the surface underneath. Virtually any coating can be removed from most any surface. Soda blasting media is FDA-approved, non-toxic, and contains no free silica; it is non-sparking, non-flammable, non-hazardous, and environmentally safe.

The blasting material consists of formulated blasting soda (chemical name is sodium bicarbonate). Blasting soda is an extremely fragile material that micro-fragments on impact, literally exploding away surface materials without damage to the substrate.

A soda blaster is a self-contained system that includes a blast generator, high-pressure compressed air, moisture decontamination system, blast hose, and a blast nozzle. The blast nozzle in soda blasting applications is not a typical wear part; as a result, nozzles can be ceramic or metal, such as tungsten carbide.

Eastwood's 50-lb. Soda Blaster can remove coatings of paint without etching or warping the metal. This blaster is ideal for stripping fiberglass, steel and aluminum. It can strip an entire car in about 8 to 12 hours, with eight to twelve 50-lb. boxes of soda media.

Master-Blaster from Eastwood is a twin blaster that allows you to switch between soda and abrasive in seconds, or mix at an infinite ratio between the two media. There's an exclusive mixing valve that allows on-the-fly mixing of the two abrasives. This reduces blasting time by half. Soda media can remove coatings on delicate substrates such as fiberglass, chrome, stainless, etc. By switching to a more aggressive abrasive, rust, heavy scaling or multiple coatings can be blasted away.
