"cloth is sold according to its weight per square yard" this is 11.5 oz/sy?!** A: Yes woven cloth and roving are specified differently. Chopped strand mat is specified in either grams per square meter or ounces per square foot. In the case of this product it would be 450 grams per square meter or 1.5 oz per square foot. We also offer a 1 oz version of this product (also epoxy compatible but the product page is out of date) it is ASIN: B01N20MS32. I hope this answers your question. **Q: can you lay carpet on this? If so what kind of carpet glue should I use on boat carpet? Can this be applied to treated plyboard?ly** A: This cloth can be applied to wood or metal using fiberglass resin. Carpet can be applied as with any other smooth surface. I don't know of a specific adhesive for marine carpet. **Q: Does this product use a styrene binder? Can I use it with epoxy?** A: It has a silane binder that is compatible with polyester, epoxy and vinylester resins. It is powder bound so it comes apart a little easier than emulsion bound and wets out easily. **Q: Could you use this to reinforce craft concrete or concrete slabs?** A: I think you would want loose fibers for that. Most likely in the 1/2" to 1" length. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great *by on Reviewed in the United States 14 September 2025* Great product as always. Been using mat for about 2 years now. ### ⭐⭐⭐⭐⭐ Love it. So affordable! I have bought this 5 times! *by on Reviewed in the United States 18 October 2025* I use this for my GFRC pots. Love it. ### ⭐⭐⭐⭐⭐ Great fiberglass *by on Reviewed in the United States 27 July 2023* Put a hole in my boat so I started by fixing it using spray foam, one layer of fiberglass and resin, then I use two layers of polyester structural filler to make the surface level. I put three more layers on of fiberglass and resin, and then gel coat and it worked great. Not the prettiest but no water got in the boat. ## Frequently Bought Together - 1.5 Oz.
