Tent & Gear Care

If you have an older "mid-priced" tent (like an REI half dome) - something that cost you between $150 and $300 and its over 5 years old, chances are that the three waterproofing elements it uses are compromised. This product is ONE of the things you need to bring back that waterproofness. And it works very well if you follow the complete process. As you can see in my video, I simulated a very strong rain storm for about 45 minutes with heavy rain and occasional sideways gusts (as usually happens in a big storm). After spraying the tent HARD for 45 minutes, I climbed inside and inspected the interior. I did not find a single drop anywhere inside the tent, and running my hands along the inside surface of the rain fly I could not detect any seepage, including along seams. There did seem to be some darkening of the rain fly fabric (as you can see in the photos) which indicates saturation of the nylon fabric, but the PU coating on the inside of the fly did its job and kept the interior dry. With a Saturday of effort, I totally restored my tent. Background: Mid-grade tents are mostly made of nylon fabric with three waterproofing steps - on the inside of the fabric there is a sprayed-on polyurethane ("PU") layer and on the outside there is a "DWR" coating (Durable Water Repellent). Think of DWR as like a "ScotchGuard" water repellent that is the first defense against water, and then the PU layer is the "block" against actual intrusion of water. The two act together to give a tent its ability to withstand rain without you getting wet inside. Where layers of fabric are sewn together, there is usually a third element - a PU "seam tape" that is laid on after the sewing process. (THIS IS WHERE MOST TENTS LEAK AFTER A FEW YEARS OF USE!) If you have an old tent and recently discovered that it is no longer waterproof, you have to address all of three of these issues - the failed seam tape, the PU coating on the inside and the DWR coating on the outside. But be careful - not ALL parts of a tent are coated with water repellents. In particular a double-walled tent like the REI Half Dome, only the absolute bottom few inches of the inner tent are coated. The rest is a lightweight breathable fabric that is essential to prevent condensation inside the tent. On the outside is a "rain fly" and it needs to be COMPLETELY waterproof. To waterproof the tent, follow these three steps. Make sure you WASH your tent (inside and out) with mild soap and water and let it dry before you start. Also, it is very helpful to pitch the inner tent and work on that first, THEN pitch the fly INSIDE OUT over the inner tent so that you can then work on that.. Plan on spending the better part of a weekend on this project in fair weather. Also, I HIGHLY recommend that you wear long sleeved shirt and pants, a cap, eye protection, and a respirator. This stuff is sticky and you do NOT want it in your lungs and on your skin! Don't do it near cars and don't do it on a windy day. Step 1. Inspect all seams on the rain fly and check to see if they are peeling or degraded. If they are, you will need to remove the peeling/degraded material with isopropyl alcohol, a fingernail, and some cloth towels. Often there will be interior parts that are glued on with this PU tape and they will come loose - clean them and mark their locations. Once everything is cleaned up, you need to use something like SeamGrip https://smile.amazon.com/Gear-Repair-Adhesive-Sealant-Ounce/dp/B01HEFRN44 to treat all the seams and also to re-glue the interior attachments that came off. Let dry for about 4 hours Step 2. Re-apply PU coating to worn areas. Wearing a respirator, climb into the tent and apply a spray on PU coating (ON THE INSIDE) to only the surfaces that are exposed when the rain fly is on. Usually this is referred to as the "bathtub" and you can see this as the dark gray area on my photos. (Heres the spray I use: https://smile.amazon.com/gp/product/B000M7RRU2). Note: if the entire interior surface is crumbly and peeling away, you may want to just buy a new tent or fly, since removing ALL the old PU coating and reapplying a new coating is going to take so much time and effort it might not be worth it). Apply a little extra around corners and seams (being careful not to spray it on the zippers!). Once the interior tent has dried, pitch the rain fly (inside out) over the tent and follow the same process to spray the interior with the PU spray, and again paying special attention to seams and corners (you'll be spraying over the seam tape you already applied in step 1, but thats OK). Step 3. Apply Nikwax DWR. Once the PU coating has dried completely (including a second coat if you've chosen to do that) you're ready for this product. Pull the rain fly off the tent and from the outside, spray the Nikwax DWR onto the "bathtub" portion of the tent's exterior. (the dark gray in my videos). Use a sponge to smooth and distribute the coating, allowing it to soak into the nylon and create and even coating. While that dries, pitch the rain fly the normal way (make sure the seam grip and PU spray are completely dry and cured!) and follow the same process with the rain fly. Make sure to use a soft sponge and spread the coating everywhere. Once it is dry, you can add a second coat if desired. The results in my video are after a single coat of Nikwax. Note that this entire process WILL add weight to your tent depending on how much material you apply. I have not weighed mine, but for a 2+ tent I'd guess I probably added 6 to 8 oz of weight, which is not insignificant for a 5 lb tent.

Easy to apply and it works, but it's not a waterproofer, only a water repellant, so unless whatever you're spraying it on is already waterproofed it's only going to work for a short time before it becomes overwhelmed. It's best use is as a first line of defense for waterproof outdoor gear like tents and backpacks, but it does also work as a repellant for jackets, etc. It is not permanent and will need to be reapplied to gear at least yearly, depending on how much you use it. If your tent is old and the waterproofing is shot (it's sticky and/or flaky and it smells like antiseptic), this will NOT fix it, not even for one trip. On clothes you're going to have to reapply it every time you wash whatever it's on and you'd be better off buying the wash in stuff from the same brand. For nylon gear, this is all but essential because sunshine basically eats nylon and the UV blocker in it prevents most of that. How much can you get out of a bottle? For me, it's enough to thoroughly treat both a 13' long 2 person tunnel tent (Naturehike Opalus 2) and another fairly large 1 person bivy tent (Sierra Designs High Side 1) with enough left over for a pair of boots. That's pretty good. Also, on Amazon this stuff can shoot as high as $30 or fall as low as $15. If you see it for $20 or less, buy it! If you see it for $15 or less, buy two! Also also, trapped vapors, whether it's water or chemical vapors from the material and waterproofing, is what causes waterproofing to fail and seam tape to peel. To prevent it, never store your tent in it's carry sack, especially if it's nylon, and never ever put it away wet. Always store it loosely piled in a mesh laundry bag and make sure it's 100% dry when you do. Nylon in particular absorbs water and the molecules can stay trapped in the fabric for hours even after it feels dry. If it got rained on, leave it out somewhere (away from sunlight) to be extra sure and then store it loosely. This goes for all your waterproofed gear. Tents, tarps, sleeping bags.... Don't store them rolled up and stuffed in a bag, preventing any vapors from escaping.

not much to say, product works great. breathed new life into my 10 year old tent. 100% worth the money if you want to care for your camping gear. i will say it sprays poorly, but its not gonna matter cause you have to use a rag to spread it across the gear surface any way

I used most of a bottle to re-waterproof my tent and fly before heading to the Wind River Range in Wyoming for 5 days. It rained every day, and I was glad I used it. I scrubbed the entire tent and fly thoroughly with warm water and a scrubber sponge first. I didn't use Tech Wash, so keep that in mind. Then i followed the instructions and sprayed a coat on, waited one minute, then wiped excess liquid off with a cloth. A piece of advice: this is water-based, so unlike some coatings and adhesives, it really does DRY, not cure. I started to work in the sun, but it was drying too fast, so i moved to the shade, which gave me more time to work. For the most part, it kept water out of the tent. Through steady, constant rain over two days, the floor stayed dry, and the fly didn't drip. However, during a high-intensity precipitation event, the floor was essentially in a puddle before the water could drain, and it pretty quickly penetrated the waterproofing. This did NOT happen at the seams, but rather, in the center of a panel of nylon that I had thoroughly re-waterproofed. I'm still giving it 4 stars because it was relatively easy to apply, and performed well, given that I would not expect a spray-on coat to keep out water under a positive pressure. Will update in future re: Solarproofing

Hard to confirm if the product worth it or not. I’ve used it on a brand new Coleman tent. Spent a completed camping week-end under the rain. No issue but I can’t tell if it’s because the tent is brand new or because of the product Quick and easy to apply. It’s great because it can also be applied while raining. To me about 15 min to protect a 10x14 tent. The coverage seems to be pretty accurate since I’ve used a bottle for 70% of the tent.

I purchased this product to re waterproof covers for outdoor furniture. I purchased 1 bottle, tested it then purchased 3 more. One bottle did one cover of a two seater.

Let’s face it : every tent says it’s water resistant. That’s fine until the sky decides to go full apocalypse and test your seams like they owe it money. Some tents have decent coatings. Some have weak ones. And more often than not, the floor has a different rating than the canopy. That’s where smart people start adding a second line of defense. This spray is that defense. The Nikwax Solarproof is water-based — which is a huge deal for me. I don’t want to mess with something flammable or toxic, especially when I’m sleeping in it. You just clean the tent, spray it on while it’s still damp, and then wipe the excess with a towel. (I personally go with microfiber — it spreads better and doesn’t scratch anything.) I’ve used it before on other tents. This time it’s on my main one, and I’ll be testing it during a rainy weekend up north. Can’t lie — I already feel more confident just knowing it’s coated. Anyway, if you’re the kind of camper who actually cares about keeping gear in top shape, this is a no-brainer. Also : is there a better sound than rain hitting the canopy while you’re warm inside? Five stars.

This waterproof spray is super easy to use — I just spray it on my tent, tarp, or backpack, and it helps keep them dry even when it rains. I liked how it felt safe and light because it’s water-based and doesn’t have a strong smell. The only thing I didn’t like is the sprayer nozzle sometimes clogs if not cleaned after each use. 😕 Still, it worked well and kept my gear protected so I’m happy with it!

I purchased this product on the recommendation of a friend. I have used it on multiple items and they have come out waterproof again. The instructions are clear. Good for multiple washes. I will be purchasing again.
