The product below is 100% full strength Diatomaceous Earth and CAN be mixed with water.

If you look at the link above...that is the product I was referring to. However, I could not get their "additional information" tab to pop up...but I knew I wasn't dreaming that I had read on the back of the bag that it can be mixed with water. So...
...Just called them … 800-801-0061 … and asked them...
… and the lady said, "the back of that bag says can be mixed with 1lb. of powder to 1 gallon of water".
She did express that she worried that it would clog some sprayers if the spray nozzle openings aren't big enough. She also said it was hard to actually "mix" with water...that is to get the product "into" the water "since it really doesn't absorb water". A direct quote from her...that sounded more like an opinion rather than fact based, which I have no way of confirming unless I go higher up.
To me, that means if you continue to shake the product often when spraying, then when the water evaporates it should perform as if put on in a dry form. I asked the lady about my thoughts, and she did say "there would be no detrimental effect of spraying the product on so long as your sprayer didn't clog".
Now, I'm sure she was just a lady that answers the phone. The reason I know this is because she had to put me on hold to get answers to my questions. That being said, if it doesn't work after getting wet, or if it shouldn't be attempted to use from a liquid sprayer, then by all means the directions to mix with water should NOT be placed on the label. Period! My guess is; they put "wet application directions" on the label of the product because it can indeed be used in such manner.
Also, I would think...
Regardless of what similar DE packaged products by St. Gabriel Laboratories say … that is whether or not other packages do or do not mention "wet application" directions... that I would submit that DE is DE...and wet application would still apply. Unless … wait for it … it is mixed with another product like kaolin clay, bentonite, or calcium, etc., then wet application may not apply.
The product I linked to was is 100% full strength Diatomaceous Earth and CAN be mixed with water.
EDIT:
As I stated, I have not used a sprayer to apply this product, but I have sprinkled it heavily in a band around the foundation of my house. Having done that, even after blowing rain, once dried after the rain, the product still seemed to work flawlessly. I am certain that over time, with additional wind and rain, that the product dissipated and reapplication would be necessary.
Given the experience I just wrote about above, seeing no ill effects from rain in the garden, after having read the label on the linked product above, and after placing a phone call to the company, I feel 100% confident the product can be wet applied with zero detrimental effects since it was explained to me that it actually will not absorb the water. That tells me each tiny dust particle only gets wet on the outside, not the inside, and explains why it can still grind insects to certain death.
The only thing that seems uncertain, and time and experience on my own will make up my mind, is this; Does it work on mites? I'd say it will if enough of the product is used.
