## Questions & Answers

**Q: How is the weight of 1.5 oz calculated?? "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  We also offer a 1 oz version of this product (also epoxy compatible but the product page is out of date)  it is ASIN: B01N20MS32.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.

    Great value

Worked great for repairing my Sunfish.

### ⭐⭐⭐⭐⭐ 







  
  
    Very high quality heavy weight glass for simple lay up shapes
  

*by B***D on Reviewed in the United States on 12 February 2024*

Good weight. Be advised the thick double ply demands considerably more resine for a giving surface coverage.

### ⭐⭐⭐⭐⭐ 







  
  
    Good quality and price. Fast delivery
  

*by A***E on Reviewed in the United States on 12 April 2024*

It lays down good. I’m a beginner at making a motorcycle seat pan. Once it setups, trim before it’s 100% hard.
