Preptech
Preptech was formed in response to a growing need for an environmentally friendly and effective alternative for removing graffiti and renewing damaged, vandalized, or simply dirty surfaces. We use the SCHMIDT Accustrip soda-blast system with sodium bicarbonate blast materials and achieve superior cleaning without causing damage to the underlying surface or the environment.
Sodium bicarbonate (soda) is a non-hazardous, food grade material that is an effective blast media for most industrial and commercial cleaning and coating removal applications. Baking soda can be dissolved with water and washed down the drain once blasting is complete. Soda Blasting is abrasive enough to remove coatings or process residue without the surface damage typically associated with other abrasive blasting media such as sand. Soda blasting makes cracks in metal and fiberglass more visible. It is water soluble, easily dissolves and is environmentally friendly, making it the perfect blast medium for greasy engine blocks and components, boat hull gel coats and road line and graffiti removal.
