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

Product worked as described
Excellent product. Shipping time very good - just a little pricey.
Didn't change fabric appearance
This product was easy to apply and dried quickly, without leaving a visible residue or changing the feel of my fabric. I can't comment on its effectiveness yet, as I used it on a Christmas gift for my husband and he hasn't opened it yet.
Rossi seam sealer has worked well to seal seams on my boat top that had to be resown .
Fast shipping, thanks
Easy to Apply and Works Great
I had a Customer with a Bimini top that was leaking really bad through some large needle holes. I the cleaned inside and outside of it with 303 Multi-Surface Cleaner, applied 303 Fabric Guard to the outside, and applied Iosso Seam Sealer to every seam inside and outside two times. He said it looks great now and has on leaks at all after a really hard rain. It took about 2 bottles to seal a large Bimini top twice, I really soaked the seams, and it goes on pretty easy and fast. I cut the foam tip down a little to get more in the seam. Note you can still see light through the holes after sealing because the sealer is clear but there are no leaks on this one.
I have not used this as yet, but am eager to see the result.
