Carboguard 510 SG Epoxy Surfacing Mortar is an epoxy-modified cementitious repair and surfacing compound engineered by Carboline for durable restoration of concrete and masonry surfaces, especially in demanding wastewater and industrial environments. This high-performance, economical mortar delivers superior bond strength, chemical resistance, and ease of application—ideal for patching, filling voids, and resurfacing deteriorated substrates prior to topcoating with Carboline lining systems.

Key Features:

• Superior Bond Strength: Excellent adhesion to concrete and masonry surfaces, even in damp conditions—no Surface Saturated Dry (SSD) required.
• Enhanced Chemical Resistance: Epoxy modification outperforms standard cement products, providing protection in aggressive wastewater environments (e.g., H₂S acid attack or microbial corrosion) when topcoated.
• Spray-Grade Efficiency: Unique formulation allows fast application by spray, trowel, or hand tools for quick project turnaround and easy repairs.
• Versatile Repair Capabilities: Fills voids in new concrete, resurfaces deteriorated areas, patches spalls, and prepares surfaces for topcoats without additional prep.

Typical Applications:

• Wastewater Infrastructure: Resurfacing deteriorated concrete in clarifiers, digesters, channels, manholes, and structures exposed to corrosive conditions; topcoat for added protection against H₂S and acids.
• Potable Water Structures: Repair and surfacing of concrete storage tanks (when topcoated with NSF-approved systems).
• Industrial & Municipal Concrete Repair: Filling voids in new concrete, patching spalled areas, and general resurfacing in treatment plants, floors, walls, and transitions.

The Carboguard 510 SG 3-gallon kit includes 3 components. It is supplied with Part A, Part B, and Part C, including Portland Cement and Sand.
