What’s the difference between slurry and wet blasting?

The terms slurry blasting and wet blasting are often used interchangeably, but slurry blasting typically refers to a specific form of wet blasting where a slurry mixture (water and abrasive media) is pumped through the blasting system. In wet blasting, water is combined with air and abrasive media to perform the blasting. The key difference is how the mixture is delivered—slurry blasting relies on a slurry pump system, while wet blasting often uses compressed air to mix the water and abrasive media.
