I am using with finishing epoxy, which normally dries clear. To get the consistency I need, there is a slight whitish haze to the dried result. **Q: volume or mass ?. In planet earth we use to have measurements "Quart Tub" really?** A: Volume. Canister was full. Material very light. Worked well with Poly resin for faring. **Q: would this work to fix a snapped surfboard?** A: It doesn’t have any repair properties, it just adds volume to your epoxy **Q: Is this hydrophobic fumed silica?** A: This is not fumed silica, but this also is not a hydrophobic filler. ## Frequently Bought Together - Fasco Epoxies White Glass Microspheres - Filler for Epoxy and Polyester Resin - Quart Tub - Fasco Epoxies - Fasco Cab-O-SIL Fumed Silica thickener in Quart tub - TotalBoat 5:1 Marine Epoxy Resin Kit for Bonding, Filleting, Coating, and Laminating - Use for Fiberglass, Wood, Carbon Fiber, Boat Building, Repairs, Woodworking (Gallon, Slow Hardener, Pumps) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/404835055-white-glass-microspheres-filler-for-epoxy-and-polyester-resin-quart](https://www.desertcart.pt/products/404835055-white-glass-microspheres-filler-for-epoxy-and-polyester-resin-quart) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-09*
