Stormseal is a water-based seam sealer designed for sealing and waterproofing stitched seams, needle holes, and leaking areas on tents, bivvies, waterproof clothing, and similar outdoor gear. It is ideal for resealing seams where the original heat applied seam tape has come loose or degraded. The sealant can also be brushed over larger areas to restore water resistance to perforated or damaged fabric. Stormseal is applied with a brush, allowing for controlled and precise application. The liquid penetrates pinholes and stitch lines, drying to a clear, flexible, and waterproof finish. It contains no VOCs and is non-toxic. Before full application, always test Stormseal on a small hidden area to ensure compatibility with the fabric. Apply in inconspicuous locations when possible, as the sealer may slightly alter the fabric appearance or reflect light differently after drying or prolonged sunlight exposure. Stormseal can be cleaned off with water while still wet, but once cured, it becomes permanent and cannot be removed with water. This 100ml bottle with a foam pad allows for neat and clean application directly over damaged seams or perforated areas.
