Baking Soda (Sodium Bicarbonate) is a one pass media, meaning you can only use it once. It is not recyclable.
While not creating an abrasive effect on the most surfaces, almost any paint, stain, smoke or contaminate can be gently removed without creating a profile on most metals.
Unlike other abrasives, each extremely friable particle shatters upon impact transferring all its energy at that moment. It is actually this transfer of energy that is responsible for the cleaning or coating removal. The shattered fractions of the particle continue to sheer away the unwanted coating. All of the energy is dissipated and the media is reduced to dust.
Baking soda is soft with a Moh 2,.5 hardness rating and with a ph.of 8.2 that is close to neutral. It is available as a food grade product and doesn't mark glass or generate a lot of heat on metals. This makes it a great media for refinishing classic cars, historical items, brick cleaning, aluminum and fibreglass boats and vehicles.
Also known as Slurry blasting, Dustless Blasting etc., this type of blasting uses a mixture of water and blast media to gently or aggressively remove existing coatings, graffiti, smoke, rust and most environmental dirt, carbon etc. We typically use crushed glass, staurolite, and garnet as blast media to do the cleaning and removal. Fine, medium and coarse grits and the ability to adjust the blast pressures determine the aggressiveness of the blasting process.
When blasting steel, anti corrosion additives are added to control flash rusting.
Historical restoration is a good fit for this process in that it is usually quicker and more cost effective than soda cleaning and does less physical damage than dry blasting. It is 95% dustless which makes it ideal for working on "main street" or high traffic areas were dust containment is an issue.
Traffic line removal on asphalt and concrete as well as brick cleaning are other applications for this process.
Dry Media Blasting
Sandblasting is the traditional and most well known form of dry blasting. Operating pressures are fixed to your air compressor operating pressures and the blast media used has been mostly silica sand.
Our media blasting equipment has adjustable air operating pressures which gives the operator more control of the blast stream. Operating pressures can vary from 20 psi to 150 psi. thus allowing us to adjust the impact of the blast media to the type of work that we are cleaning.
The use of different blast media gives us the ability to match different media products to the desired end result.
From copper and nickel slag for removing heavy mill scale rust on steel truck frames and beams to using fine grit garnet for profiling steel in preparation for powder coating. We use glass bead for gentle finishing on wood or stainless steel and walnut shell for more aggressive cleaning.
Whether the cleaning is inside or out, from fibreglass boat bottoms to log homes, we have the combinations to effectively give you a clean consistent result
