Outdoor Waterproofing Spray

Works great, and does an excellent job of waterproofing. It is easy to apply and covers well.

This spray works really well for adding a water-repellent layer to fabrics. I used it on outdoor cushions and a canopy, and water now beads right off the surface. It also helps reduce stains and provides UV protection, which keeps colors from fading as quickly. The spray goes on evenly and dries clear without leaving a sticky residue. Be sure to apply it in a well-ventilated area, as the smell is strong at first. Overall, it’s an effective and dependable waterproofing spray.

Works pretty good. Didn’t think it worked at first. Sprayed some on my baseball style hat an a pair of canvas shoes like vans and my expensive leather work boots. Discolored the boots at first but it dries clear. Didn’t mess up anything. Ran some water over the bill of my hat to see if it repelled the water and it didn’t. I was a little disappointed because I bought a whole gallon. Was kinda pricey. But the other day it rained and I just happened to have both the hat and boots on that I sprayed and they were both completely waterproof. I was so surprised. I stomped my feet and all the water came right off and took off my hat and shook it and it was dry. Definitely recommend. Can’t wait to spray more stuff.

Works great

Water dripped directly through my boats t top canvas and boat cover due to their age. I sprayed both with this and water just beads up and rolls off now. Great product and easy to apply.

I use this every year to treat my boat covers. After washing them in the spring I treat the covers with this and it has worked very well for the past five years. I use a garden sprayer to put it on.

****Downgraded from 5 star to 3. See update below for the writeup on that. my boat is 16 years old and even though I have only had the boat for a year, based on the condition of the vinyl I can tell that the cockpit cover for it has been used religiously for all 16 of those years. The condition of the canvas had me convinced that I would need to order a new cockpit cover, but I decided to give this product a try to see if I could make the canvas functional again. While it looks old and weathered, it still functions to protect the vinyl from the sun, though very little functionality exists for rain protection. Now with this product I am positive I can stretch a few more years of functionality out of this cockpit cover before having to completely replace it. I took this video this evening since I was working on the boat when a rainstorm came out of nowhere. It is kinda dark, but you can see the water beading up on the canvas since it is under my bimini top and you can see the water just running off the canvas cover. Edit to add info: Coverage - 1 Gallon did my entire Bimini Top, Camper Extension Top, and 90% of the cockpit cover for my 24ft boat. I purchased another gallon since I ran out on the cockpit cover which was the piece that REALLY needed to be done. When I got the next gallon in I redid the entire cockpit cover and also the covers for my bimini top and camper top extension. I REALLY overdid the cockpit cover since it had seen the most sun damage over the course of the boats life. Even though I did 90% of the cockpit cover few days earlier, when the new gallon came in I REALLY saturated it a second time since I had plenty of waterproofing to work with. Before I took the video I assumed that the rain would just roll off as long as the canvas was taught when buttoned up, I was surprised when I got caught in the rain that even without being pulled taught the waterproofing did its job and made the water just roll off completely. I used a standard garden pump sprayer for application and did the bimini top while it was on the bimini top poles, I just set it up in my yard when I did it. The cockpit cover I draped over a couple small step ladders that I have, my garbage bin, and my recycle bin. This allowed me to hang it all out with nothing touching the ground. I started at the top of the step ladders and worked my way down each side so any overage would drip down and soak downwards to the sections that had yet to be done. This method worked well for me both times I did the cockpit cover. I hope all of this info is helpful to someone. New Canvas = hundreds/thousands of dollars Waterproofing = less than 50 per gallon It's a no brainer folks. Oh yeah, for those environmentally minded folks, and those who care WAY too much about how green their grass is, my grass was not affected by the chemicals. *******Edit 12/4/2015***** After surviving the season I have come by to downgrade my review to 3 stars. While I did not experience major issues with my canvas disintegrating like many reviewers mentioned I did notice that all of my seams started having issues. Granted my canvas was made in 2000, but it survived fairly well considering. After a couple times of removing my canvas cockpit cover I noticed that the threads in the seams started coming apart. My canvas is still functional but by the end of next season I will definitely need to get a new cockpit cover and bimini covers. It did a great job at re-waterproofing, but is not friendly on the stitching/seams. If you want to extend the life this will do the trick, but I think you may as well try the sunbrella approved stuff out there for a couple dollars more and hope that it works better on the stitching and doesn't compromise the integrity of the stitches. Again, for functionality 3 stars - compatibility with canvas and stitching that resulted in it deteriorating at a fast rate I had to knock it down a couple stars, but at the end of the day the waterproofing does actually work as advertised.

Great stuff ! Works very well repelling the water off my boat cover. Recommend highly.
