Scotchgard Heavy Duty Water Shield 1 Can, 400 ml - Water Repellent Spray, Ideal For Outerwear, Tents, Backpacks, Canvas, Polyester And Nylon

Product Information

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.” In general, Scotchgard™ Heavy Duty Water Shield can be used on cotton, cotton blends, leather, suede, nylon, canvas, and polyester. 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. 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. 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.

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 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. 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.Be sure to pay close attention to seams as they are quite often the weak spot for leaks or stitching breaks. 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. 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. 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.

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. If your 1st 2 coatings have proven to be successful then attempt to cover the rest of the canopy top.

The predominant brands making the more eco-friendly water based applications are Nikwax and Revivex.
