About this deal

They actually kind of adhere to the individual fibers, like an old-fashioned telephone cord—they wrap around the fibers," says Heidi Allen, the vice president of marketing at Nikwax. "They have a little stretchiness to them." 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. 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.

Waxes and wash-ins can be applied indoors—a benefit if it’s raining or snowing or if you don’t have an outdoor workspace where you can apply the products. Wash-ins are easy; they only require using your washing machine, and some can even be done by hand-washing. Wash-ins are especially popular for down items since the waterproofing product is also meant for the feathers inside the item and the outer layer. Granger’s Wash + Repel Down is easy to use: You just add the liquid to your washing machine’s soap slot using the bottle’s cap as a measuring device. This product has the added benefit of washing and waterproofing at once; it’s a one-step process that only requires running the machine once. After washing, you machine-dry the item on low heat, and Grangers recommends using dryer balls to help fluff the down inside. The Scotchgard Heavy Duty Water Shield is one of the best waterproof sprays to protect your outdoor furniture. The extensive range of materials you can use it on is impressive. Be sure to buy two or more if you have a lot of fabric you need to apply the spray on. Camp Dry vs ScotchgardTraditionally, 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. This product covers an astonishing 465 square feet of fabric. That’s a mid-sized room of fabric you could make waterproof. But to be fair, the product is considerably larger than the other products on our list.

Be sure to pay close attention to seams as they are quite often the weak spot for leaks or stitching breaks. Basically, polyester is able to protect you from most everyday situations, like if you step out in the rain or the snow. It won’t remain dry or protect you from water if it’s underwater for a prolonged period of time though.A suitable alternative to the Scotchgard is the Atsko Silicone Water Guard. Side-by-side there’s not much between them. However some people report that Atsko can slightly decolorize some fabrics (especially white ones) and Scotchgard seems specially formulated to have greater coverage.
