What is SODA BLASTING?
 Soda Blasting is a process that can strip almost any surface in an efficient and safe manner.  Although similar to traditional sand blasting, Baking Soda Blasting has the significant advantage of cleaning the surface without causing harm to the substrate or the environment.  Soda Blasting removes paint, coatings, grease, oils, gasket material and surface corrosion from a variety of metals, alloys, plastics, wood, masonry and composites without surface damage or distortion.
Unlike other media, Baking Soda does not use friction to remove coatings so there is no heat created. This prevents warping and pitting of metal. It is prefect for aluminium and glass cleaning and being spark proof can be used in hazardous areas no other blast process can be. It is great for cleaning wooden beams and is the kindest way to clean wood without the damage associated with sand or grit blasting.
  Will SODA BLASTING work on fibreglass?
Yes, Soda Blasting is the safest blasting media for fibreglass.  Due to the softness of the medium, when applied properly, you can remove coatings without damage to the fiberglass leaving a very smooth finish. So car bodies can be safely stripped and we use it to remove anti-fouling from boat hulls.
Can SODA BLASTING be used on projects with the glass still in?
Baking Soda Blasting will not harm glass, rubber, chromed metal or polished stainless steel. It is perfect for cleaning glass curtain walling.
  Is SODA BLASTING safe?
YES, there are no solvents or strippers in the coating removal process.  The only protection gear needed for the process is a respirator which is used for protection from breathing the dust generated by the process and hearing protection for the noise. So long as the coating being removed allows the soda can be left to wash into normal drains, 100% safely. It is harmless to pets and humans BUT, if allowed to lie on grass and plants it will affect the pH level of the soil and kill grass etc. Affected areas should be blown off and rinsed down. Covering before hand is a good idea and essential for fish ponds etc. It is a noisy and dusty process so if you have neighbours you must check with them before arranging any work.
Will SODA BLASTING remove smoke damage?
Soda Blasting will remove smoke damage on Brick, Stone, Ceramic, Glass, Mortar, Concrete and Wood without damage. Also, baking soda will help absorb the smoke odour while it is cleaning. It can be swept up and removed along with the odour! It can remove and neutralise mold as well.
  Will SODA BLASTING damage or warp body panels?
Soda Bicarbonate is an extremely soft media (2.4 on a Mohs scale, talcum powder is 1 on the scale).  We use Baking Soda that is manufactured specifically for media blasting by Arm and Hammer. All other media remove coatings by friction, which causes heat to be generated.  Baking Soda particles explode upon contact with the surface creating energy.  The release of this explosive energy blasts off the coating without generating enough heat to cause even extremely thin metals to warp.  Using Baking Soda you can safely strip a soft drink can without distortion. You  can successfully strip cars, airframes etc. without removing the glass, chrome or rubber as the Baking Soda will not harm any of these surfaces.
After  SODA BLASTING what kind of prep work should be done before painting?
On wood surfaces we recommend a citric acid or 1 part vinegar to 3 part water solution wash before applying any coatings. Steel panels should be keyed using a DA sander, Aluminium will be etched primed and this is enhanced by the pH level of soda. Where suitable, on boat hulls for instance just wash down with plain water. There are all kinds of horror stories on the internet about soda blasted projects not taking paint. This is frankly wrong. It is down to bad prep nothing to do with soda blasting.
How quick will rust occur after SODA BLASTING?
Soda Bicarbonate is a natural RUST INHIBITOR, when using it as a blast medium it will leave a coating on the metal that will inhibit rust for a long period of time. Also, unlike aggressive blasting the surface of the metal is not broken and this prevents rust getting a key It is necessary to keep the project stored in a dry area and if done so then months can pass before any gingering shows up.
