Product Information

Full details

The Stormsure Stormseal Seam Sealer is an ideal solution for outdoor enthusiasts, professional marquee hirers, and expedition teams looking to maintain large quantities of fabric gear. This water-based, non-toxic formula offers a high-performance waterproof barrier for tents, bivvies, and outdoor clothing, ensuring long-term protection against the elements. While its 5-litre volume is perfect for industrial-scale repair and maintenance, individual users may find the container size excessive for small, one-off projects.

FAQs

Is this safe for use on all types of tents?

It is suitable for most synthetic and natural canvas materials, but we recommend a patch test first to ensure compatibility with your specific fabric coating.

Do I need to dilute the sealer?

No, the formula is ready-to-use and should be applied directly from the container.

How long does it take to fully cure?

While it may be touch-dry in a few hours, we recommend allowing 24 hours for a full cure before subjecting the fabric to rain or heavy use.

Can I use this on clothing?

Yes, it is suitable for outdoor clothing, though it is best applied only to the seams rather than broad fabric panels to maintain breathability.

How should I clean my brushes after use?

Since it is a water-based product, you can clean your brushes or application tools using warm soapy water immediately after use.

Will this sealer expire?

If stored correctly in a sealed container, it remains effective for a long period, though you should avoid freezing temperatures.

Troubleshooting

Sealer is not adhering to the fabric

Ensure the fabric was not treated with heavy silicone-based waterproofing sprays previously, as these can prevent the sealer from soaking into the fibers.

The finish appears cloudy

The product may have been applied too thick. Remove excess with a damp cloth and allow it to cure thinly; it will usually clear up as it dries fully.

Long drying time

High humidity or low temperatures can extend curing. Use a fan or place the gear in a warm, dry room to accelerate the evaporation process.

Pros and Cons

Pros

  • Large volume is highly cost-effective for bulk maintenance
  • Non-toxic and VOC-free for safer handling
  • Dries to a flexible, clear, and durable finish
  • Excellent for both sealing new seams and repairing pinhole leaks

Cons

  • 5-litre bulk size may be impractical for casual users with limited storage
  • Requires proper application tools like brushes or sponges not included
  • Drying time may be longer than solvent-based alternatives

Setup, Compatibility & Care

Application Prep: Ensure the target fabric is clean, dry, and free from dirt or oils before application. Use a mild detergent if necessary, and ensure the fabric is completely dry before applying the Stormseal.

Compatibility: This product is compatible with most synthetic outdoor fabrics including polyester and nylon. Always perform a small patch test on an inconspicuous area if you are unsure of material compatibility.

Storage & Care: Keep the container tightly sealed in a cool, dry place away from direct sunlight. Because this is a water-based product, protect it from freezing temperatures during storage, as this can degrade the formula.
