How do I make fabric superhydrophobic/waterproof? Answered
I am looking for a solution to make a fabric waterproof. (including cotton and polycotton blends/synthetics) I am looking to do something cheaper than buying a store-bought solution, such as making it from scratch. I have looked into purchasing octadecyltrichlorosilane, but it is both expensive and hazardous to ship ($25 hazmat fee) If possible I am also looking into finding a solution that is non-toxic and is safe for use on people.
