How should you store a tent after waterproofing it to ensure the protection is maintained?

The best way to store a waterproofed tent is to roll it up when it is completely dry and store it in a dry, cool and dark place, preferably in a breathable bag or box. The waterproof coating will then remain intact until you need the tent again. In this article, we answer the most frequently asked questions about correct storage after waterproofing.

How long should a tent be left to dry before you put it away?

An impregnated tent must be left to dry completely for at least 24 to 48 hours before you put it away. In damp or cold weather, this can take up to 72 hours. Storing the tent whilst the fabric is still damp is the quickest way to encourage mould growth and damage the waterproof coating.

After applying a waterproofing agent to your fabric, the protective layer penetrates deep into the fibres of the canvas, polyester or nylon. Those fibres need time to dry completely and allow the waterproofing to set. Can you still feel any coolness or dampness when you touch it? If so, the tent isn’t ready to be packed away yet.

Ideally, hang the tent outdoors or in a well-ventilated area. Avoid direct sunlight whilst it is drying, as intense UV radiation can damage the freshly applied waterproofing coating before it has fully cured. A shaded spot with a light breeze is ideal. Also check the seams and corners particularly carefully, as these dry more slowly than the flat surface of the fabric.

What is the best way to roll up a waterproof tent?

The best way to roll up a waterproofed tent is loosely and without any sharp creases. Roll up the fabric in a gentle, even motion, avoiding sharp creases or wrinkles. Tight creases in the same place can cause the waterproof coating to crack or flake over time.

When packing the tent away again, alternate the direction in which you roll it up compared to previous seasons. This will prevent the same areas from being subjected to repeated strain. Some campers do not roll up their tent but fold it loosely into a spacious bag, which further reduces the pressure on the waterproof coating.

It is best to use a breathable storage bag rather than an airtight plastic bag. Breathable material prevents any residual moisture from being trapped, which can lead to mould growth. A cotton bag or a specialised tent bag with ventilation is best suited for this purpose.

What storage conditions damage the waterproofing layer?

A tent’s waterproof coating is damaged by moisture, heat, sharp creases and prolonged exposure to UV light. A damp, warm or poorly ventilated storage area is the greatest enemy of a properly waterproofed fabric.

Avoid the following storage conditions:

• Damp areas such as cellars or sheds without ventilation, where condensation damages the fibres and encourages mould growth
• High temperatures such as an attic in summer, where heat can break down the preservatives
• Direct exposure to sunlight through a window, which causes UV damage to both the fabric and the protective coating
• Contact with sharp objects or heavy pressure, which damages the fibres and locally compromises the water-repellent effect
• Plastic airtight bags, which retain moisture and encourage mould growth

The ideal storage place is dry, cool, dark and well-ventilated. A cupboard or a dry storage area at room temperature is perfectly suitable for most tents and awnings.

How can you tell if the waterproofing is still effective after storage?

You can check whether the waterproofing is still effective by sprinkling water onto the fabric. If the water remains in small droplets and beads up on the surface, the waterproofing layer is still working properly. If the water soaks into the fabric or forms wet patches, the protection has worn off and the fabric needs to be waterproofed again.

This test, also known as the pearl test, is the most reliable way to assess the water-repellent properties of your tent fabric. You can carry it out straight after taking the tent out of storage, well before the camping season begins. This way, you’ll avoid any nasty surprises if you find yourself caught in the middle of a downpour.

Please also look out for the following signs that the impregnation has become less effective:

• The fabric feels heavier in the rain than usual
• There is visible discolouration or damp patches following contact with water
• The outside of the tent feels damp from the inside, even though there is no condensation

Do you need to re-waterproof a tent after every winter storage period?

You don’t automatically need to re-waterproof a tent after every period of winter storage. Whether re-waterproofing is necessary depends on how intensively the tent has been used, how well it has been stored, and whether the bead test indicates that its water-repellent properties have diminished.

A tent that has been thoroughly cleaned and stored in a dry place after the previous season can last for several years without needing a full waterproofing treatment. Tents that have been used intensively, washed several times or exposed to poor storage conditions will require more frequent maintenance.

As a rule of thumb, carry out the pearl test at the start of every new camping season. If the tent passes the test, you can set off with confidence. If it fails, it’s wise to re-waterproof it before you set off. That way, you can be sure your tent will keep you dry when it really matters.
