Product Information

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. Traditionally, treatments to reapply that water repellent coating have been silicone based but they are not considered very environmentally friendly. Relatively new to the market are a few water based products. When it comes to the propellants used, at least 3m tells you what they are, while some manufacturers will only say, “hydrocarbons.” If your 1st 2 coatings have proven to be successful then attempt to cover the rest of the canopy top.

One benefit of each product is that by being water based, it can be applied to clean fabric that is dry or wet. 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. In general, Scotchgard™ Heavy Duty Water Shield can be used on cotton, cotton blends, leather, suede, nylon, canvas, and polyester. Added to the solvent issue is the type of propellants used in the aerosol cans, isobutane and propane, both hydrocarbons which are not exactly environmentally friendly.Be sure to pay close attention to seams as they are quite often the weak spot for leaks or stitching breaks. 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. Coverage per can varies with fabric type: from about 5,5 m2 for light nylon to about 1,8 m2 for heavier fabrics

This spray is already proven to waterproof tents and is therefore ideal for EZ up canopies, event shelters and pop up gazebos. Scotchgard™ Heavy Duty Water Shield provides an ultimate protection for clothing and outer gear against common weather conditions . When applying Revivex, try and lay flat whatever you are treating, like Nikwax, it is a thin solution and will run off the fabric. Instructions on the can are sparse just saying to spray it on the fabric. What worked best was to spray the treatment on, spread it out and then let it penetrate. After a few minutes, dry according to the instructions for the item treated. 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. Instructions say to set the gear up, but the solution is very thin so it is best to lay it out flat so it does not run off. In this way you will get the best coverage.

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. Only the Atsko/Sno-Seal spray products have done away with the use of this volatile mixture to power the aerosol applicator, using CO2 captured as a byproduct from other manufacturers. Another plus to this system is that less propellant is needed and more of the waterproofing product ends up in the can. Mould often appears when the fabric is kept moist for a prolonged period and as this protector spray repels moisture the rainwater will just run off the fabric.

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. 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.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.” 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. Once treated, the fabric was allowed to dry for 48 hours and then exposed to water to see how they performed. Water Based Products
