Crushed Glass:
Crushed glass is our abrasive of choice.
It is inert with no free silica and so it is safe for the environment and people who may be near a blasting
operation. It is quite effective at removing rust and paint coatings. It also works well for cleaning brick or stone to
improve its appearance or to remove graffiti.
We stock it in both a medium and a very fine grade.
The dust that is created will not harm that which it may settle on. If left on the ground it will work its way
harmlessly in to the dirt and grass and it can be swept up from hard surfaces.
Walnut:
Walnut is a softer media which can be used to remove paint from more delicate surfaces such as fiberglass
without harming chrome or glass, but will not remove rust. The advantage of this media is that no special
cleaning is needed after blasting to have your corvette or boat bottom repainted. It is also a good choice for wood
or brick when clean up is not desirable as the walnut is biodegradable and will eventually disappear after enough
rain and time passes.
Sodium bicarbonate: "Soda"Blasting
Soda is the softest of the blast medias. It works differently than an abrasive by exploding on a surface, which
separates the bonds of a coating to its substrate. It has the advantage of being water soluble. Soda can be used
to degrease equipment without harming wiring and hoses and will not cause blockage or damage to moving
parts like pistons and gears and is safe on chrome and glass. It is the same product used in baking, but is
formulated in to crystals shaped best for blasting. When used to clean up smoke damage it helps to absorb
odors just as a small box placed in your refrigerator at home would. Some troubles with soda is that it has a
high ph value. There can be quite a bit of dust, like a cloud of smoke, from blasting with it. The dust has some
potential to harm auto paint if not washed off and it can also harm grass and some types of bushes. Although it
is often used to remove paint from fiberglass we now recommend walnut to avoid the extensive cleaning
needed to assure good paint adhesion.
