How much do I need to spray a curtain that is 3 yards by 10 yards with two coats?

Not sure about that, but I do know that we used one full can to spray 4 outdoor seat cushions. I just recently bought 6 cans to do a new couch with two coats.

Can you use this to make cloth shower curtains waterproof?

We would recommend checking the cleaning codes on the item and preforming a colorfastness and texture change test first in a discrete area. You may also want to verify with the manufacture of the item for protector products safe for the material. You will have to reapply after every time you wash the curtain. This will NOT waterproof shower curtain, it will only provide water repellency.

Does this work on faux suede sofas? If not what would you recommend?

Hello, thank you for asking! The Scotchgard(TM) Fabric Water Shield is the recommended product for indoor furniture. For faux suede, we recommend testing in first in an inconspicuous area for colorfastness, and to be sure it does not affect the nap of the fabric. If you have any additional questions, please feel free to reach out to our team at 1-800-367-7683 Mo-Fri 8am-4:30pm CT. Should you call, please mention reference #29490767.
