I was hoping one of you smart people might know of a type of cloth that is both waterproof & fireproof for a prototype I'm making. The closest thing I've found is a BBQ grill mat, but it's too stiff- I need it to be like regular cloth (I tried to post a link to the grill mat but it said only "insiders" can post links).

I've also tried to take regular cloth or waterproof cloth & make it fireproof (using VHT Flameproof Coating Paint) but it didn't work- the material was not flame proof & it melted. I've tried a few other products with the same result. I've researched & researched & then researched some more but nothing I've found meets all of my qualifications. I'm thinking of some type of cloth that is impregnated with silicone but I haven't been able to find it.

Thank you in advance for your help

Edit: I have no idea why the title just says "water"- I put in "Waterproof & fireproof cloth?" as my title

I can't post links here either. But if you go to

alibaba   website and type in 'waterproof fireproof cloth' you will find some there.

Hi Richard-

Without spending a lot of money, it is quite possible to 'make' your own waterproof fabrics.  Rustoleum has a spray on kit that works o.k. as long as the fabric is not continually abraded.  Continued heavy wear or use seems to rub the coating off.

For a quick prototype and proof of concept, it may be worth the time and lower cost vs a specialty fabric.   Once you are comfortable with early results, then you might invest more later on the better materials.   Just some thoughts- good luck!

Remember Richard needs fireproof also. The Rustoleum Technical Data Sheet makes me think OF REALLY QUICK flame up 

10. Stability and Reactivity CONDITIONS TO AVOID: Avoid temperatures above 120°F (49°C). Avoid contact with strong acid and strong bases. Avoid all possible sources of ignition. INCOMPATIBILITY: Incompatible with strong oxidizing agents, strong acids and strong alkalies. HAZARDOUS DECOMPOSITION: By open flame, carbon monoxi

Yep, I did see that. : )

I wanted to point out that some materials can be water proofed easily and cheaply.   He did mention that he was looking for those protections but I was not sure if they were concurrent conditions to be met.  In other words, maybe the product has to water proof for the first test/evaluation and THEN the fire test stage is next?

Rain-X also makes a water proof coating, but is now dis-continued.


If he needed both qualities present at the same time, then maybe simple Nomex cloth will suffice. 


 Firefighters and Race Car drivers wear this stuff all the time.   If the cloth is inherently strong and fire-proof but NOT waterproof, then the aftermarket coatings idea might be a good avenue to check on.  Sorry I didn't clarify my statement well enough earlier.
