Ensuring your tent is still waterproof is a must before you set off on your camping trips. Even if you’d bought a waterproof tent years ago, the effectiveness of the water resistant materials can deteriorate over time, leaving you with a tent that could potentially leak and endure further damage.
There are many ways of waterproofing your tent to keep it in the best condition it can possibly be in, but perhaps the most effective way of doing so involves coating your tent in a hydrophobic spray.
Hydrophobic sprays, otherwise known as waterproofing sprays, act as a barrier between the tent and the rain, and due to their composition, allow water to slide straight off- hence the name hydrophobic. These sprays are handy to use before a trip, and can be sprayed over an assembled tent any time during dry weather to give its protection against the elements a boost.
It’s important to re-waterproof your tent periodically to keep it functioning as properly. No waterproof spray is permanent, and some sprays don’t last as long as others. Make sure to check if the spray you are using is resistant to UV or if it will evaporate quickly over time.
How To Use Waterproofing Sprays On A Tent
For the best results, follow the directions listed on your waterproofing spray bottle. In addition to this, there are several other general tips and tricks to keep in mind when waterproofing your tent using waterproofing spray.
- Make sure your tent is clean and dry before re-waterproofing it. This will prevent you from needing to clean it for another while, thus prolonging the waterproofing sealant you’re about to use. Waterproof sprays often become less effective with continuous exposure to water, washing or general wear. If you clean your tent before applying any spray, it will increase the spray’s longevity if you don’t wash it again for a while.
- Make sure there is no leakage due to physical damage on your tent. Using a waterproof spray can only help so much – if your tent has a hole in it causing it to leak, then you’re best patching it up before applying any sealant. Luckily, we have a guide for patching tents.
- Make sure your tent is laid out as flat as possible when spraying each individual section. This gives it a much more even coat and also makes you less likely to miss any parts of the structure with the spray.
- Hold your spray approximately six inches from the surface you’re spraying. Of course, you should follow the advice written on the bottle, but as a general rule of thumb, holding the bottle around six inches away is ideal.
- Sometimes your tent only needs a spot-repair. Testing your tent’s water resistance after washing it can help determine whether or not it needs a full spray of if there are only some areas of concern. This can save you leftover spray, along with time.
REMEMBER: If you’re planning on camping in bear country, be wary of any scents that waterproofing sprays may have. Luckily, most sprays that are manufactured are odorless, but it’s always good to double check.
