Abrasive blasting commonly known as "SANDBLASTING" is the process of using compressed air to propel the desired media at any surface to clean coatings, rust, debur materials or prepare a surface for a wide variety of coatings.
WARNING
It should be noted that the long used media "SILICA SAND" is now illegal to use. It has been determined by the government to cause siliceous that causes your lungs to become plugged up with a glass like fibrous. OSHA has been fining people for using it. I have heard of fines as high as $50,000.00. Please avoid breathing silica dust if not for your health then the fines!
I use a wide variety of blasting media for different applications, let me list a few for you.
Coal Slag - Garnet - Aluminum Oxide - Corn Cobs - Plastic - Steel Shot - Walnut Shells - Glass - Silicon Oxide
Each has a different characteristic for each specific surface and the desired profile for your coating or finish. Give Mike a call, explain your project and he can suggest the best media for your desired outcome.
