What is the difference between wet sandblasting and dry sandblasting?

Wet sandblasting means water is used in the technique to remove debris such as paint, tex-cote or old stucco, from a structure. This is the most common sandblasting technique.

Dry sandblasting does not utilize water. Typically dry sandblasting is not permitted except by special permission from the city. Permission may be granted only in those situations where wet sandblasting cannot be done due to peculiar circumstances. Any application for dry sandblasting needs to state why wet sandblasting cannot be used.
