Sodablasting is a process where sodium bicarbonate is applied against a surface using
compressed air. An early use was to restore the Statue of Liberty in the late 1980s.
Sodablasting is a non-destructive method for many applications in cleaning, paint
stripping, automotive restoration, industrial equipment maintenance, rust removal,
graffiti removal, molecular steel passivation against rust, oil removal by saponification
and translocation, masonry cleaning and restoration, soot remediation, boat hull
cleaning, food processing facilities and equipment.
It can be used for cleaning cars, boat hulls, masonry, and food processing equipment.
Sodablasting can also be used to remove graffiti and to clean structural steel.
One paint manufacturer recommends against using their automotive epoxy primer over
soda blasted substrates. A refinish specialist from a major vehicle manufacturer
does not recommend soda blasting prior to automotive refinishing.
A Sodablaster is a self contained system that includes a blast generator, high pressure
compressed air, moisture decontamination system, blast hose, and a blast nozzle that
is capable of handling dry or wet blasting material. The blast nozzle should be tungsten
carbide and in Sodablasting applications is not a typical wear part.
The blasting material consists of formulated sodium bicarbonate (also known as baking
soda). Blasting soda is an extremely friable material that has micro fragmentation
on impact, literally exploding away surface materials without damage to the substrate.
A Sodablaster differs from a sand blaster in that the Sodablaster is not gravity-fed,
meaning it will not come out of the bottom of the pressure vessel.
