Fiberglass Chopped Strand Mat Tape - Strong, Lightweight Glass Fiber for Structural Reinforcement & Repair

Fibre Glast's Chopped Strand Mat is the key to your next successful boat repair. Quickly build thickness and support between structural layers. Fibre Glast's industrial-strength CSM wets out fast and makes it easy to yield reliable results in your DIY marine repairs. Use with polyester or vinyl ester resin, but do not use with epoxy resin.

Get that boat back in the water with confidence. Chopped Strand Mat Rolls are available in 4-inch wide 10-yard and 86-yard rolls. Pro Tip: Tear the chopped strand mat, don't cut it. This maintains the length of fibers along the torn edge, creating stronger bonds when fabricating in multiple layers.
