How to Re-Waterproof a Bivvy

While your bivvy will have been supplied with full waterproofing as standard, over time and through wear and tear, it will start to leak. The choice is then – do you buy a new bivvy, or is it possible to re-waterproof your existing one? In fact, you can re-waterproof a bivvy just as you can any other waterproofed item, and it is the most cost-effective method of getting the most out of it!

How do you go about it? Well, you will need to buy one of the many tent and awning waterproofing kits on the market, but it’s not a difficult job to do, and the first thing to do is find out where those leaks are, and how serious they have become.

Take a bit of time when you are home and set your bivvy up in the garden. Then, either wait for the good old British rain to do its trick, or get your hosepipe on the bivvy and you’ll be able to see where the water is coming through the fabric. Mark these areas so you know where they are when you take the bivvy down, and you’re ready to start the easy process of re-waterproofing! Now you want to know which product to use!

Which Waterproofing Agent?

We have a looked at a few waterproofing agents and will tell you about some of them, but bear in mind this is not a comprehensive list as there are many such products. You’ll find some labelled as tent or awning waterproofing items; this doesn’t matter – your bivvy is a tent, and is made from very similar materials, and they will all work well. Here are a few of the brands we found:

NikWax Spray On

Sale
Nikwax Tx. Direct Spray On Spray On Waterproofer - 0.3lt
  • Adds or renews water repellency and revives breathability
  • Prolongs the life of gear and optimises outdoor performance
  • Easy spray-on application method for clothing with wicking liners

The most popular method of re-waterproofing is to use a spray product such as this one, from NikWax. You simply spray on one coat – all over or just where the leaks are showing – and leave it to dry. It claims to strengthen the material itself, protects against UV damage, and can be used on all synthetic materials so will certainly work on your bivvy. Available in 0,5 litres up to 5litres, it’s popular and widely available in tent and hardware stores.

Iosso Water Repellent

IOSSO WATER REPELLENT PROOFER PROTECTOR 32oz Boat Sail PVC Canvas Tent Awning
  • Effective on all fabrics. It protects from water, soil, oil, bird droppings, and environmental pollutants.
  • Recommended for use on awnings, canopies, canvas, tents, patio furniture, cushions, umbrellas, spa covers, tarps, boat covers, bimini tops, hunting fabrics, camping gear, leather, synthetics, and vinyl.
  • Formula is non-solvent, and non-silicon.

This product, which is available both ready to use in a spray bottle or as a concentrated solution that you can make up when you need it, creates a coating that actually repels water, and is useful against everything from bird droppings to soil and even environmental pollutants. Easy to use, it’s available in many sizes, is a non-silicon product, and will be very effective on your bivvy.

Grangers Waterproofer

Sale
Grangers Clothing Wash and Repel 1 Litre
  • Formulated to clean and restore the water-repellence of all outdoor clothing
  • Fluorocarbon-free and environmentally Responsible
  • Requires heat activation ideally via a tumble dryer

This silicon-based solution comes in a tin and you are required to decant it into a spray gun. If that’s OK by you it might be the choice to go for, as it is effective on all synthetic materials, adds UV protection, and the five-litre metal tin is safe to store away for future use on your bivvy, tent or awning, or indeed any other waterproof items that might need proofing.

Kampa Hydrophobic Spray

Kampa Super Hydrophobic Waterproofing Spray 750ml
  • Repels water, oil & stains
  • Suitable for breathable fabrics
  • Contains a UV sunscreen to help reduce fading and degradation

Another that repels water, this comes from the extensive range of camping products in the Kampa brand, and is very popular and easy to use. Designed to deal with oil and stains as well as to repel water, this one is in a 750ml spray can which will fit neatly into a cupboard when not in use, and is a popular item. It’s also entirely natural and provides UV proofing too.

These are just a few of the more popular re-waterproofing agents that we have found, and you can rest assured none contain any potential toxins. But, is it worth re-waterproofing your bivvy, or should you take this moment to buy a new one?

Is Re-Waterproofing Worth It?

You need to make the decision between re-waterproofing and buying a new bivvy. Here’s the thing – if you’re bivvy is leaking absolutely everywhere, in other words it’s really had its day, then a new one is certainly a good idea.

But, if you just have leaks in a few places, why go to the trouble of searching for an ideal replacement, and the expense of a new bivvy, when you can simply buy one of these re-proofing agents, spend a few minutes repairing it, and then it’s done? Your old faithful bivvy lives again, and you save a lot of money!

It’s definitely worth re-waterproofing unless, as we said, the damage is too far gone, so check your bivvy out now, and you’ll soon have it dry and comfortable again.
