What exactly is tent fabric waterproofing?
Impregnating tent fabric involves applying a water-repellent protective coating to the fabric of your tent, awning or canopy. This treatment ensures that water cannot penetrate the fibres but rolls off, keeping the fabric dry and mould-free.
The waterproofing process works by allowing microscopic particles to penetrate the fabric’s structure. These particles form an invisible barrier that repels water but allows air to pass through, ensuring your tent remains breathable. This prevents condensation and keeps your tent comfortable during rainy camping trips.
New tent fabric often comes with a factory-applied waterproofing treatment, but this wears off over time due to use, UV exposure and washing the fabric. That is why regular re-impregnation is essential to maintain the waterproof properties of your camping equipment.
Why is waterproofing so important for your tent?
Waterproofing protects your tent from water damage and mould, and significantly extends the life of the tent fabric. Without proper waterproofing, water can seep into the fibres, leading to leaks, wet gear and an unpleasant camping experience.
The benefits of properly waterproofed tent fabric go beyond simply being waterproof. An effective waterproofing layer prevents dirt and stains from penetrating deep into the fabric, making it much easier to clean the tent fabric. Mud, leaves and other dirt remain on the surface and wash off easily with water.
What’s more, waterproofing provides protection against UV rays, meaning your tent’s colours are less likely to fade and the fabric is less likely to deteriorate. This is particularly important for campers who use their tent regularly or leave it out in the sun for long periods during their holidays.

How often should you waterproof your tent fabric?
You should waterproof your tent fabric about once or twice a year, depending on how often you go camping and the conditions in which you use your tent. Frequent use in rainy or dusty environments requires more frequent waterproofing.
There are clear signs that indicate when it is time for a new waterproofing treatment. If water droplets no longer roll off the fabric but soak into it, the protective coating has worn off. Also, if you notice that your tent takes longer to dry after rain or dew, this is a sign that the waterproofing needs to be renewed.
For optimal tent fabric care, we recommend waterproofing the fabric at the start of the camping season, after giving it a thorough clean. If you camp frequently or use your tent for long periods, an extra treatment halfway through the season may be advisable. Please ensure that you always remove any stains from the tent fabric before applying the waterproofing treatment.
What is the difference between impregnation and a waterproof coating?
Impregnation makes tent fabric water-repellent whilst keeping it breathable, whereas a waterproof coating forms an impermeable layer that keeps out both water and air. Impregnation penetrates the fibres; a coating forms a film on the surface.
The main difference lies in the fabric’s breathability. Impregnated tent fabric allows water vapour to pass through, preventing condensation from forming inside the tent. A waterproof coating completely seals the fabric, which can make the tent feel stuffy and cause water droplets to form on the inside due to condensation.
For tent fabric, impregnation is therefore usually the better choice. It provides sufficient protection against rain and moisture, whilst maintaining comfort inside the tent. Waterproof coatings are mainly used for materials that do not need to be breathable, such as groundsheets or certain types of tarpaulins.
How to correctly apply impregnation agent to tent fabric?
Apply the waterproofing agent to clean, dry tent fabric by spreading the product evenly using a spray bottle or cloth, and allow it to soak in completely before storing the tent. Work in dry weather and avoid direct sunlight whilst applying the product.
Always start by thoroughly cleaning your tent fabric. First, remove all stains and green deposits using a suitable cleaning product. Then rinse the fabric thoroughly and leave it to dry completely before you start waterproofing it. Moisture in the fabric can hinder the effectiveness of the waterproofing agent.
Apply the waterproofing agent systematically, starting at the top of the tent and working your way down. Ensure even coverage and pay particular attention to seams and corners where water can collect. After application, allow the product to soak in according to the instructions—usually a few hours to a full day—before using or storing the tent again.

Can I impregnate my tent while it is still wet?
No, the tent fabric must be completely dry before you apply the waterproofing treatment. Moisture in the fabric prevents the waterproofing treatment from penetrating the fibres properly, which significantly reduces its protective effect. You should therefore always let your tent air-dry thoroughly first.
What happens if I use too much wood preservative?
Using too much waterproofing agent can leave a sticky film on the tent fabric and may impair its breathability. Always follow the dosage instructions on the packaging and apply the product in thin, even layers. When it comes to waterproofing, more is not always better.
Can I use standard household water-repellent sprays on my tent?
This is not recommended. Household water-repellent sprays are not designed for outdoor fabrics and can damage the breathability of tent fabric. Always use specialist waterproofing products for tent fabric that have been specifically developed for camping equipment.
How can I check whether my tent is still properly waterproofed?
Spray a little water onto the tent fabric. If the droplets roll off immediately without being absorbed, the waterproofing is still effective. If the water is slowly absorbed into the fabric or remains on the surface, it is time for a new waterproofing treatment.
Should I also impregnate the inside of my tent?
No, only waterproof the outside of your tent. The inside needs to remain breathable so that moisture can escape from inside. Waterproofing the inside can lead to condensation problems and make the tent feel stuffy.
How long should I wait after impregnation before I can use my tent again?
Wait at least 24 hours after applying the waterproofing treatment before using or storing the tent. The product needs time to be fully absorbed and to cure. Check the specific instructions on your waterproofing treatment, as drying times may vary from product to product.
Can I waterproof my tent if there are still stains on it?
No, always clean your tent thoroughly before waterproofing it. Stains and dirt can prevent the waterproofing agent from adhering properly to the fabric. First, use a suitable cleaning product to remove all dirt, rinse thoroughly and allow to dry before waterproofing.
