Not only will this product improve the level of water resistance but it can help to keep the fabric of the canopy cleaner and help prevent mould.Once you have sprayed the liquid onto the surface you must allow it to dry, whilst ensuring that your pets are kept well away until fully dry. If your 1st 2 coatings have proven to be successful then attempt to cover the rest of the canopy top. Nikwax prides itself on being one of the safest waterproofing products on the market with water used to deliver what Nikwax calls an, “elastic, water-repellent synthetic polymer” onto the fabric. According to Nikwax, the “Solarproof” components of the compound will protect from the UV rays that damage synthetic fabrics to extend the life of your gear.

Again, using these solvents makes coating the fabric easy with deep penetration. Once dry, it also repelled water extremely well. As far as how long it will last, instructions say to apply annually. Scotchgard has been around in one form or another for a long time and the Heavy Duty Water Shield is yet another, using a “proprietary” silicone formula. Like the others it replaces the DWR on the fabric and it too uses petroleum solvents to carry the product to the surface. It also uses isobutane and propane as a propellant. When spraying this on remember it is flammable, so avoid any open flames and excess will run off the fabric so be aware of drips getting on nearby surfaces.Camp Dry was added to the test simply because it is so easy to find in most big box stores, but it did not do as well as any of the other products tested. Once treated, the fabric was allowed to dry for 48 hours and then exposed to water to see how they performed.

One benefit of each product is that by being water based, it can be applied to clean fabric that is dry or wet.

It uses water as the carrier and is applied from an aerosol can with no dangerous propellants. The spray can is a “bag on valve” which allows the can to totally empty so you get all the coating you paid for.

Be sure to pay close attention to seams as they are quite often the weak spot for leaks or stitching breaks. Like the other silicone products, it uses petroleum solvents to carry the compound to the fabric and it also uses isobutane and propane as a propellant, but they do not tell you this on the can, it is simply listed as, “hydrocarbons.” Application of the product is straightforward, spray a light coating on a clean surface and let it dry, but instructions say to add a second coating after four hours. Even with this, the treated surface did not repel water as well as any of the other products tested. Firstly, spray a small section of the canvas of your EZ up canopy. Apply by holding the can 8 inches away from the product and use a gentle sweeping motion to apply evenly. If you use Scotchgard™ Heavy Duty Water Shield to treat outdoor gear with white rubber soles, the soles may turn yellow – if that happens, clean the affected area as soon as possible with rubbing alcohol.We collected up a group of waterproofing compounds to try out side-by-side. Each of the products was applied to a clean section of uncoated ripstop nylon in the weight range normally used in tents. Though both products performed as promised, Revivex won out by literally a nose in my test as Nikwax had an odd odor. Even after 48 hours it was still perceptible and two weeks later, it was mild, but still there. Another plus for Revivex is the allowance for breathability offering a wide range of products that can be treated, from tents to waterproof shells. Silicone Water Repellents
