Fabric Waterproof Spray, 1 Gallon Heavy Duty Protector and Repellent for Outdoor Marine Canvas, Boat Tops, Vinyl Seats, Tents, Clothing, Boots, Jackets, and Clothes

Clean surface thoroughly before applying

Waterproofed my boat canvas T top and it worked great

Application was easy.Now I need boating season to know how well itworks.

I laundered our shower curtain liner, dried it thoroughly, and saturated it on one side with “water proof spray.” After drying it completely I put it back in use (with the waterproofed side inside the shower). This product did not return the liner back to its water shedding nature. It still soaks through but remains good enough to not allow water to soak the fabric outer curtain. Given the cost of the spray (took almost the whole bottle with enough left over for a light repeat treatment) I think a new liner is a better solution.

I needed a waterproofing solution for my popup camper to prevent fabric permeation or penetration by water. This did it and there's a lot left over for the next treatment. I recommend spraying interior and exterior canvas. I used this in tandem with GE Advanced 30 minute silicone to seal out leaks and repair the waterproofing solutions in place. The canvas is 24 years old on my unit so it's remarkable it has lasted. You need to retreat the canvas at least once a year. This is really important if you don't want water coming through the fabric and wetting your bedding, pillows, and clothes. I live in my camper year round.

The spray bottle was defective. The cap could not be tightened. It would keep spinning around. Had to transfer liquid into a spray bottle we happened to have on hand. Very poor quality control. Disappointing for an American made product. Container probably from China.

Use this on all of our outdoor furniture, and it seems to be doing a good job. Hoping it lasts the rest of the season.

There is enough in the bottle to use on a hammock. Good product so far.
