There´s a few different aproaches to wetblasting to....the cabinets and some pots use a slurry and pump it up to the nossle.
I have a nossle i use in my normal blasting setup that ad a tiny amount of water and i can use whatever media with it.
Water acts like a cushion and coolant so calms down the cutting of the media and cools the surface to avoid warping.
