85ml Waterproof Epoxy Metal Sealant for Repairing Stainless Steel, Copper, and Aluminium

This two-part epoxy metal sealant provides a professional-grade solution for repairing cracks, holes, and leaks in metal surfaces. Its waterproof formulation bonds strongly to stainless steel, copper, and aluminium, making it ideal for metal casting repairs, pipe mending, or fixing structural components. Supplied in an 85ml kit complete with application tools, it offers a practical and lasting repair for workshops, industrial maintenance, and serious DIY projects where a durable, watertight seal is essential.

Features and Construction

The sealant is a two-component system designed for maximum adhesion and waterproof performance on common metals. Each component plays a specific role in creating a strong, cured bond that can withstand environmental exposure.

Material and Build

The adhesive's strength comes from its precise two-part formula. Part A contains epoxy resin and polymer resin, which together form the main adhesive body. Part B is a curing agent and additive that triggers the hardening process. When mixed, these components react to create a rigid, waterproof seal that bonds securely to the prepared metal surface, suitable for structural repairs.

Size and Practical Fit

The product is supplied as an 85ml kit, a volume suited to a range of repair jobs. It is available for purchase as a single unit or in a convenient pack of five, allowing you to stock up for larger projects or multiple repairs. The kit format includes all necessary tools, making it a self-contained solution ready for use straight from the pack.

Uses and Placement

This metal sealant is engineered for practical, heavy-duty applications where metal integrity needs restoring. Its primary use is in professional and workshop environments, but it is also accessible for skilled home use.

Event or Professional Use

In professional settings, this glue is ideal for repairing metal castings, sealing joints in metal fabrication, or fixing leaks in copper pipes and aluminium fittings. Its waterproof nature makes it suitable for outdoor equipment, marine fittings, or any metal component exposed to moisture, providing a reliable seal that prevents further corrosion or failure.

Everyday Home Use

For the experienced DIY enthusiast, the kit offers a way to mend broken metal tools, repair garden furniture, or fix cracks in metal pots and pans. The included push rod, scraper, and sandpaper guide you through surface preparation and application, helping achieve a clean, professional-standard repair even outside a workshop environment.

Benefits and Buying Value

Choosing this metal sealant brings several practical advantages, centred on its completeness as a kit and the specific performance of its adhesive formula.

Reuse and Low Maintenance

The repair created by this epoxy is intended to be permanent, restoring the item to service and eliminating the need for frequent re-fixes. Once cured, the bond is waterproof and resistant to many environmental factors, reducing future maintenance. The ability to buy a five-pack also supports efficient reuse across multiple projects over time.

Why Choose This Product

This product stands out for its targeted formulation for stainless steel, copper, and aluminium, and its completeness as a ready-to-use kit. Unlike generic adhesives, its two-part epoxy system is designed for structural metal repairs where a waterproof seal is critical. The inclusion of applicator tools and sandpaper ensures you have everything needed for proper surface preparation and application, leading to a more successful and durable repair outcome.
