Iosso^® Seam Sealer protects and seals sewn seams on boat covers, awnings, tents and backpacks. Seam Sealer does not affect the look or texture of the fabric. It can be used on a variety of fabrics, including cotton, polyester, Sunbrella^® and synthetic woven fabrics. Due to the seam construction on vinyl-coated and vinyl-laminated fabrics, water repellency may vary.

Size: 4 oz. bottle

Bottle features a sponge top for easy application.

To Use: Push sponge applicator down on fabric, allowing the fluid to completely soak the seam. For best results, apply to both sides of fabric at the seam. Let dry for 24 hours before exposing to weather.

Note: Seam sealer should be re-applied after the fabric is washed or after several exposures to weather.
