FGCI Glass Microspheres – The Easy Way to Create Lightweight, Smooth Composite Repairs Take your composite projects to the next level with FGCI Glass Microspheres. These lightweight, hollow glass microspheres are the perfect additive for epoxy, polyester, and vinyl ester resins, making it easy to create smooth, lightweight fillers and fairing compounds that are a breeze to sand. Whether you're repairing a boat, restoring a vehicle, or working on a fiberglass project, FGCI Glass Microspheres help fill cracks, voids, and fiberglass weave for a clean, professional-looking finish. Because they reduce the weight of your resin mixture, they're ideal for applications where strength and low weight matter. The clear, chemically stable microspheres blend easily with most resin systems without affecting color, giving you consistent, reliable results every time.

Coverage A general guideline: Light fairing mix: Approximately 1 part microspheres to 1–2 parts resin by volume can create a spreadable filler for smoothing and surface fairing. Thicker filling applications: More microspheres can be added to create a lighter, thicker paste for filling larger voids and shaping. Final coverage: The finished mixture can vary widely, but a thin fairing layer may cover several square feet per mixed quart, while heavier fills will cover less area.
