Abrasive blasting can be accomplished both wet and dry. A dry process will provide maximum abrasiveness and can be done with a wide variety of media. Dry blasting can be dusty and is some situations where that is an issue, wet blasting is recommended.
Wet blasting involves using both an abrasive grit and high-pressure water. The water will aid in the blasting process and will keep the dust to a minimum. Wet blasting can be an issue if water run-off or ground contamination is of concern.
Another concern for wet blasting is flash rusting of steel surfaces after blasting. Adding a small amount of the Kramco 1510 Rust Inhibitor Liquid Compound will mitigate flash rusting and provides some longer-term protection against corrosion until the surface can be coated. Typically, about an 80:1 dilution is used (80 gallons of water to 1 gallon of Kramco 1510) in order to provide adequate protection.
