What does mould on canvas look like?
Mould comes in many shapes and sizes, and on canvas, it usually looks like tiny black, blue or green specks. Mould can eventually rot your canvas and sleeping in a mouldy tent can be harmful to people with allergies and asthma.
Is mildew on canvas different from mould?
Excess moisture can cause mildew, and this fungus will form on your canvas tent if stored while still wet. Even if you purchase a mould resistant canvas tent, mildew could still occur in certain humid conditions.
Canvas products, including tents, may have been initially treated with mould resistant products but this dissolves over time through general use. Therefore, it’s essential to protect your canvas products from all types of fungi growth.
How to stop mildew from spreading
Mildew can break the fibres of canvas and create black stains which are hard to remove. It is essential to protect your tent against mildew and its ability to spread when left unchecked.
- Always properly dry your tent before storing
- Clean your tent regularly and after each use
- Store your tent in a cotton canvas bag, not plastic
- Store all ropes, pegs and other tent accessories in a separate bag, not with the tent
- Ensure you have plenty of ventilation if cooking inside the tent to avoid condensation
- Be careful with all dishwashing products, sunscreen and other lotions as they may adversely affect the waterproofness of your tent
