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.

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.

Great product. I am restoring a vintage fiberglass boat and this stuff works great for stringers, transom, hull, and anything else needing to be laminated.

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.
