How to use

Clean and dry the area to be sealed; remove loose threads, dirt and old adhesive residues. Apply a thin, even bead of the sealant along the stitched or damaged seam, ensuring full coverage of needle holes and exposed thread. Smooth the sealant with a gloved finger or applicator to form a continuous coating. Allow the product to cure fully according to ambient temperature and humidity before exposing the item to wet conditions. For larger repairs, apply additional layers after the first layer has cured.

Usage recommendations

Use in a well-ventilated area and test on a small inconspicuous patch if compatibility with a specific fabric finish is unknown. Store upright at moderate temperatures and keep the cap tightly closed to preserve product consistency. For long seams, work in sections and allow adequate curing time to ensure a continuous waterproof barrier.
