What are the recommendations on surface preparation or media blasting?
The substrate must be free of loose rust, paint, moisture, dirt, mildew, oily substances, wax and loose particles. It is extremely important to remove embedded salts (chlorides) from the surface prior to the application of a new coating system. The surface to be coated must be completely dry. Although it is not always necessary to blast surfaces prior to a Rust Bullet application, Soda Blasting and Dry Ice Blasting are two methods of media blasting that are effective, clean and environmentally safe. Both media are sound options and clean up will be relatively minor including the drying procedure after the dry ice blasting.
