How long does tent fabric need to dry after being waterproofed?
After impregnation, the tent fabric must be left to dry completely for at least 24 hours before you fold it up or put it away. In damp weather, this process may take up to 48 hours to ensure optimum water repellency.
The drying time depends on various factors, such as humidity, temperature and ventilation. Ensure that the tent fabric hangs freely and does not touch any other surfaces whilst drying. A well-ventilated room or the open air will speed up the process considerably. Check whether the fabric is completely dry by gently running your hand over the surface; it should feel dry, without any stickiness.
Rushing this process may reduce the effectiveness of the impregnation. The impregnating agent needs time to be fully absorbed into the fibres and to form a protective layer. Folding the fabric too soon may result in the agent being distributed unevenly or in damp patches forming.
What is the best way to fold waterproof tent fabric?
Fold the waterproofed tent fabric loosely, with generous folds, and avoid tight folds which could damage the water-repellent coating. Always start with the cleanest section and work your way towards the dirtiest parts.
The correct folding method begins by spreading the tent fabric out on a clean surface. Make wide, gentle folds approximately 50–60 centimetres wide. This prevents sharp creases that could damage the waterproof coating. Ideally, place acid-free paper or a thin cotton cloth between the folds to minimise friction.
Whilst folding, check that no dirt or small stones get trapped between the folds. These can cause scuff marks during storage, which may impair the fabric’s water-repellent properties. For extra-large tent fabrics, it is advisable to work in pairs to avoid putting unnecessary strain on the material.

Where is the best place to store tent fabric after waterproofing it?
Store impregnated tent fabric in a dry, cool place with good ventilation and stable temperatures between 10 and 20 degrees Celsius. Avoid attics, cellars and other areas with extreme temperature fluctuations or high humidity.
An ideal storage area has a relative humidity of no more than 60 per cent. Storage rooms, sheds or garages may be suitable, provided they are well ventilated and do not suffer from condensation problems. Do not place the tent fabric directly on concrete floors; instead, use wooden pallets or planks to allow air to circulate beneath the fabric.
Protect the tent fabric from direct sunlight and heat from radiators or heating systems. UV radiation can break down the waterproofing layer, whilst heat can cause the material to shrink or damage the coating. A dark, evenly tempered room offers the best protection for long-term storage.
How can you prevent mould when storing impregnated tent fabric?
Prevent mould by storing the tent fabric completely dry, checking it regularly for damp patches and ensuring there is sufficient air circulation. Use moisture-absorbing agents, such as silica gel, in the storage area if the humidity is high.
Mould tends to form particularly when damp is combined with heat and stagnant air. You should therefore check monthly that the tent fabric still feels dry and that there are no musty odours. At the first signs of damp, you should immediately spread out the tent fabric to dry and improve ventilation in the storage area.
Preventative measures include using breathable storage covers instead of plastic bags, which can cause condensation. Do not place the tent fabric directly against external walls, where cold air can cause condensation. If you are unsure about the humidity levels, you can use a hygrometer to monitor the conditions and use a dehumidifier if necessary.
When should you re-waterproof your tent fabric after storage?
The tent fabric needs to be re-waterproofed if water droplets no longer bead up on the surface or if the fabric starts to absorb water during use. This usually happens after 1–2 seasons, depending on usage and storage conditions.
Test the water-repellency by dropping a few drops of water onto different areas of the tent fabric. If the fabric is properly waterproofed, the drops will roll off immediately without being absorbed. If the water is slowly absorbed or leaves dark stains, the fabric needs to be re-waterproofed. Pay particular attention to areas that have been under pressure during storage, such as creases and contact points.
The frequency of re-treatment depends on various factors. Intensive use, exposure to UV radiation and poor storage conditions shorten the duration of the waterproofing treatment. Tent fabric that is stored correctly under optimal conditions generally retains its water-repellent properties for longer than fabric that has been left in damp or warm areas.

Can I leave the tent fabric to dry indoors after waterproofing it?
Yes, tent fabric can be dried indoors, but ensure there is excellent ventilation. Open windows and doors to allow air to circulate and use a fan if necessary. Avoid areas with high humidity, such as bathrooms or cellars, and keep the tent fabric away from heat sources that could damage the material.
What should I do if my tent fabric smells musty after being stored?
Spreid het tentdoek onmiddellijk uit in een goed geventileerde ruimte of buiten (niet in direct zonlicht). Laat het volledig luchten en controleer op vochtplekken. Bij aanhoudende geur reinig je het tentdoek met Hood & Tent Shampoo en laat het grondig drogen voordat je het opnieuw impregnert en opbergt.
What is the maximum length of time I can store waterproofed tent fabric?
When stored correctly under optimal conditions (dry, cool, well-ventilated), waterproofed tent fabric can be kept for years. However, check its water-repellency and general condition every season. The waterproofing layer deteriorates slowly, even when stored properly, so test it regularly and reapply the treatment if necessary.
Is it normal for newly waterproofed tent fabric to have a chemical smell?
Yes, a slight chemical odour after waterproofing is normal and will disappear as the fabric dries. Ensure there is good ventilation during the drying process. If the odour is still strong after 48 hours, check that you haven’t used too much waterproofing agent and leave the tent fabric to air for longer.
Can I store different types of tent fabric together?
It is best to store different materials (canvas, polyester, nylon) separately as they have different properties. Canvas requires more ventilation than synthetic materials. If you have to store them together, place breathable material such as cotton cloths between the different tent fabrics.
How can I tell if the storage area is too damp for tent fabric?
Use a hygrometer to measure the humidity – this should remain below 60%. Other signs include condensation on windows or walls, musty odours, or metal objects in the room rusting. If in doubt, place moisture-absorbing agents in the room and improve ventilation.
