I recently ran out of PTFE and in an effort to save money bought powdered PTFE. Will it work the same way and if so should i mix it with water and how much?

Fluon is made from a micro-powder of uniformly sized PTFE in an aqueous dispersion. The water is used to distribute the particles on surfaces to form a uniform, thin film coating.

There is no way that water will dissolve PTFE. You might be able to get a dispersion using an organic solvent or an emulsifying agent (soap). The intermolecular forces of PTFE are extremely low so entropy is going to dominate mixing, which means that higher temperatures will help immensely. But if you're using an organic solvent heating is likely to cause it to spontaneously combust.
Soap and hot water might be your best bet, but you'll have to shake like crazy and apply immediately. Organic solvent + soap might be better, but do you really want to start messing around with dangerous chemicals to get this to work? Probably not.
Be careful. I'm not a chemist, and you should do your own research for safety. MSDS is a good way to start. Always work in a ventilated area.

Your safety points are important, though PTFE is only a real danger when it comes into contact with a flame.
As far as dissolving goes, there are only two ingredients in commercial Fluon: one is the PTFE and the other is a surfactant. So yeah, it's possible the surfactant is needed to form the suspension; though I would note that the MSDS indicates its function is that of a pH buffer to prevent microbial growth. I imagine the materials scientist at any fluoroplastics shop would have better insight than any of us.

Has anyone had any luck with the powdered PTFE?
I'm just getting into the hobby and trying to decide if I can go with the powder PTFE instead of the liquid. I'm kinda hoping I can just mix with a bit of water as needed rather than emulsify a large batch.
