Reliable seam repair for waterproof confidence

Stormseal Seam Sealer is the perfect solution for repairing and waterproofing seams and needle holes on tents, bivvys, waterproof clothing, and other non-watertight seams. This water-based styrene-acrylic polymer dispersion penetrates pinholes and seams, drying clear to create a flexible, impermeable waterproof surface.

Non-toxic and VOC-free, it’s safe to use and easy to clean up before drying. One 100ml bottle can cover up to 12m of seam (1-inch wide), making it an efficient and practical choice for outdoor enthusiasts.

Simply shake well, pour into a container, and use the included brush to apply a thin film over the seam or stitching. Stormseal cures in 15–25 minutes, leaving a clear, durable, and waterproof finish. Perfect for ensuring your gear stays protected and ready for any adventure.
