Epoxy Concrete Patching Compound 7 Gallon Kit

FAS-STONE Epoxy Patching Compound is a professional-grade, two-part epoxy repair system engineered for demanding concrete, masonry, metal, wood, and fiberglass applications. Formulated for strength, durability, and versatility, this patching compound delivers a rock-hard cure that outperforms traditional cement patch materials. Once mixed, the resin and hardener create a dense, non-sag epoxy mortar that bonds aggressively to both porous and non-porous surfaces—even in wet or underwater conditions. Designed for industrial, marine, and residential use, FAS-STONE is ideal for repairing cracks, filling holes, rebuilding damaged edges, resurfacing worn concrete, and bonding new concrete to old. The cured material is exceptionally resistant to impact, abrasion, moisture, chemicals, and heavy traffic, making it suitable for high-wear environments such as warehouses, docks, pools, seawalls, and industrial floors. This easy-to-use formula can also be extended with clean sand (up to a 1:1 ratio) to increase coverage and create an economical epoxy cement. Once cured, FAS-STONE can be drilled, tapped, sanded, or machined, providing maximum flexibility for structural and surface repairs. Whether you’re patching concrete, repairing underwater surfaces, or rebuilding structural components, FAS-STONE delivers long-lasting performance you can trust.
