Product Details
Fiberglass Mat, also known as Chopped Strand Mat or CSM for short, is a non-woven material typically used for laminate build-up and repair work. It consists of glass fibers laid randomly across each other and held together by a styrene binder.
For wetting out this form of glass fiber material, use a styrene thinned resin such as Polyester as it readily dissolves the styrene bonding agent that attaches the strands. This tooling cloth can be used with epoxy resin, but requires additional time and labor to saturate properly.
This fiberglass chopped strand mat is offered in various weights per square foot. The lightest version, veil mat, is used commonly as a finishing layer to mask any print-thru in a laminate schedule. This particular veil mat uses longer, thinner fibers than heavier mat weights also offered here. Coarser, heavier mat is commonly used for bulk, random axis strength buildup and is also an excellent initial layer when bonding repair work.

Complete order fail

Beware, ship date is make believe. Ordered 25 yds of 3/4 CSM on the 30th. Checked the order in my profile on the 4th and said it shipped on the 31st with no tracking info. Called on the 9th to inquire and customer service said it never shipped. Cost me somewhere between 3-4 days idle. Very disappointed.

Works for me

I used this product to build up the space left after I removed the rotten wood in the repair of my trawler's door. I found this messy and difficult to work with mostly because I really don't know what I'm doing. The good news is in the end it does the job.

Good delicate material
10 years ago
I actually bought this to use in a situation it was not created for I assume. I have used Nu Wall fiberglass to repair cracked plaster walls, it works very well using it and their other products. This fiberglass mat is much lighter and delicate, so I thought it would be useful on smaller cracks. It worked, I used a glue and then plastered over it successfully to hide the crack. I am sure it would work great as a fiber/epoxy build up for curves etc.

1708

I requested the 1708 be rolled rather than folded. Received the product on a nice sturdy cardboard tube. The CSM I also ordered did not, which made it much more difficult to unroll and cut.

Fantastic deal

Don't buy the small packaged fiberglass mat from the local hardware store if you're going to be using a lot of it, and you usually need more than you first think. I made the hardware store mistake and paid about 8x too much per sq foot than through JTD. It comes in a nice sized roll, easy to use and the size let's you utilize big pieces of Fiberglass or cut it small ones. It's a convenient size/shape and at a great price.

Q: null Is this CMS mat OK to be used with Total Boat 5:1 epoxy resin ? I are replacing engine mount stringers and I was going to also use this CMS and then use a 1708 fiberglass cloth and / or triaxial fiberglass cloth over wood ? Hopefully epoxy resin will work as a wet lay up on all of these cloths?
6 years ago1 Answer
A: CSM is not as easy to use with epoxy resins as it is with styrene thinned resins such as polyester or vinyl ester. Fiberglass cloth is generally the product to be used with epoxy resins. CSM still can be used with epoxy but it does not wet out nearly as well, and more laborious to saturate properly.

Q: null Will epoxy work with chopped glass mat ok?
6 years ago1 Answer
A: Chopped strand glass mat is really designed for use with a styrene thinned product such as polyester resin or vinyl ester because the styrene breaks down the binder that attaches the strands, and allowing it to wet out very easily. Epoxy will saturate the mat to a degree, but it is laborious to work it in. There are usually cloth materials with a light and fine weave that allow you do do similar things.
