1708 +/- 45 Biaxial Fiberglass (Multiple Package Sizes Available)

What is 1708 Fiberglass?

“1708” indicates the weight of each layer. For example, the +/- 45 biaxial weave cloth is 17 oz. per square yard, & the mat backing is 8 oz. per square yard, so the total weight is 25 oz. per square yard.

Flat non-crimped fiber sheet yield reduced print-thru & higher stiffness than woven fabric
Ideal for repairs, tabbing, & reinforcing.
Our general purpose fiberglass cloth is great for a wide variety of applications including, hand layup by brush or roller, spray on applications, marine, transportation, auto body, aerospace, general purpose laminating, FRP parts, boat, roving waterproof sealant for floor.

Working with resin can be a smelly affair. Resin’s chemical reaction to surfaces can smell foul just like other brands, but once it has cured, no odor can be detected. Best to keep your DIY project outdoors for a day or two, then savor the exceptional quality later on once it has dried out.

✅ Perfect for base coats
✅ Ideal for rush projects
✅ Great sealer for wood repairs
✅ A Premium product same that is used in most repair shops & manufacturers
✅ Cost-effective & better quality than other resins on the market.

Shipped fast !

Product was as advertised and shipped fast


First timer on home fiberglass repair. Watched a lot of videos and read a lot of reviews. This product worked like a dream. Used it with the BIAXIAL FIBERGLASS. Fixed a massive fiberglass tub repair hole. Easy to use.

Great Gelcoat repair

I've used this product a number of times over the years and always have great results. The resin mixture is most important in my opinion and patience, but this cloth definitely helps. It lays nicely and takes resin well.
