Tent Waterproofing Spray Buying Guide
Each brand of spray-on tent waterproofing has a different formula that helps it work, so there are different characteristics you need to pay attention to so you can find the best tent waterproofing spray for your situation.
Here’s three key factors you need to keep in mind when picking waterproofing spray for tents:
Silicone Is Best. There are water-based sprays that work very well, but in our testing and reviews we found that the best tent waterproofing spray choices are silicone-based.
Silicone is excellent for forming a waterproof barrier on your tent or other gear, with the fibers of the material actually “linking” together to form a cross pattern to keep moisture away.
Silicone is also good at reducing stains and repelling oils.
Spray Type. Some tent waterproofing sprays will come in an aerosol can for easy, even access, while others will come in a spray bottle.
Other options may include a solution that you apply with a sponge.
There’s not a certain type of tent spray that is superior, but it does come down to making sure you choose the type that is easiest for you and that you’ll actually use.
The Type Of Fabric It Works On. The majority of tents are made of nylon or polyester, but some can be made of canvas or other materials.
Know the material your tent and other gear is made of, and be sure to select a waterproofing solution that is intended for that fabric type.
Breathability. Some cheaper waterproofing tent sprays do a great job of blocking moisture, but they sacrifice breathability.
You don’t want to reduce airflow in your tent because it’ll make it hold in heat more and make it much more stuffy inside the tent, ruining your camping experience.
Size. Consider the size of your tent in overall square footage, and be sure to pick a waterproofing tent spray that will at least cover that full area.
You don’t want to get started just to run out half way through the job!
How To Waterproof A Tent With Spray
- Start with a clean tent and rain fly, checking the instructions on the spray bottle to verify whether the target material should be dry or wet when applying the waterproofing spray.
- Find a spot that is not in direct sunlight and has low wind exposure, but is also well ventilated (like an open garage).
- Spray the waterproofing solution on the outside of the tent and rain fly in an even, thin layer. You may need to let it sit for a few minutes (or hours) depending on the manufacturer’s directions.
- Spray in overlapping strokes with about an inch overlap, being sure not to overspray. If you notice runs or drips, back up a few inches or move your spray faster horizontally.
- Wipe off any excess waterproofing spray with a cloth and allow it to dry fully for the curing time indicated on the product packaging. It’s best if this drying is done outdoors.
- You can apply several coats if needed, repeating this process each time.
- Allow the tent to dry fully overnight before packing it back up and storing it.
How To Make Homemade Waterproofing Spray For A Tent
Homemade waterproofing spray for a tent is an option if you prefer to make your own products.
Here’s what you’ll need to make a DIY tent waterproofing spray:
- 2 cups linseed oil
- 2 oz. of beeswax
- 2 oz. of rosin
Directions:
- Heat the beeswax and rosin in the oven at 250 degrees until they are melted.
- In a small pot, heat the linseed oil until it comes to a boil, then remove from heat.
- Remove both from heat and mix together.
- One cool, apply to a tent in even coats, up to three coats maximum (apply one coat per day and allow to fully dry between applications).
- A spray bottle is best, but you can also use a paint brush or sponge in a pinch.
