Workshop Repair

Restore metal without the welding hassle

Cracks, casting holes and damaged threaded fittings can stop a repair cold. Mix, apply and rebuild the damaged area with strong adhesion designed for demanding metal repairs.

BUILT FOR METAL

Purpose-Built Repair Features

Every part of the kit answers a practical workshop question: will it bond, can it handle the setting, is mixing manageable and where can it be used?

CORE ADHESION

Strong Metal Bond

The packaging claim of strong adhesion fits the repairs shown: cracks, casting defects and damaged metal areas. Press the mixed material into sound, prepared metal rather than applying over oil, rust or loose debris.

HEAT RESISTANCE

Handles Hotter Repairs

High-temperature resistance is one of the stated performance claims. Confirm the part's actual operating conditions first, and always apply to a cool, isolated component.

CONTROLLED MIXING

Two Parts, One Repair

The purpose-built dual-component cartridge comes with transparent mixing cups and a spatula. That gives you a more deliberate preparation process than improvised two-part mixing.

WIDE APPLICATION

Seals Beyond Surface Cracks

Use cases include pipe cracks, sand holes, gas holes, corrosion-related damage and threaded metal components. The wide application claim makes it useful across garage, plumbing and maintenance work.

Used it on a cracked metal component in my garage. Having a non-welding option made the repair much less of a production.

The cups and spatula are a small detail, but they made the casting repair feel controlled instead of improvised.

I used it around a damaged threaded fitting. Cleaner than bringing the welder into that tight area.

I bought it to learn a more controlled adhesive repair process for small cracks and casting defects. The mixing step takes a little patience.

Used it where the welding equipment could not reach. Straightforward tube application and easy to keep in the repair bag.

The 100ml size was useful for several small water-exposed metal repairs. The cartridge is less convenient for very large repairs.

THE WORKFLOW

Mix, Apply, Restore

Surface preparation is the central success factor. Set up the repair before opening the cartridge.

1

Isolate The Part

Remove the component from active heat, pressure, water flow or movement. Work only on a cool, dry and accessible repair area.

2

Prepare Sound Metal

Remove oil, rust, loose debris and other contamination. Expose a firm surrounding surface so the adhesive can contact sound metal.

3

Mix The Components

Use the transparent cup and included spatula to mix the two components thoroughly according to the product directions.

4

Fill And Shape

Press the gray adhesive into the crack, hole or damaged fitting area. Shape the repair while working carefully around the surrounding metal.

5

Inspect Before Service

Allow the repair to set according to the product directions, then inspect the bond and confirm that the application suits the part's conditions.

A Repair Path When Welding Is Not Practical

A damaged metal part does not always need to go straight to replacement. This two-component metal bonding adhesive gives you a measured way to address suitable cracks, casting defects and fitting damage.

CHAPTER 01

The Repair That Cannot Wait

A small crack, casting void or damaged fitting can hold up an entire repair. Left exposed, the defect can invite leaks, corrosion and more pressure on the surrounding part.

CHAPTER 02

A Welder Is Not Always Practical

Awkward access, missing equipment and added heat can make welding the wrong first move for a small repair. A metal repair epoxy putty gives you another route when the part is isolated and suitable for adhesive restoration.

CHAPTER 03

Mix In, Build Back

The dual-component cartridge, transparent cups and mixing spatula keep preparation clear. Mix the two parts, work the gray adhesive into the prepared damage and shape the repair with control.

Back To The Workbench

The damaged area is filled and sealed so the repair can move forward. Use the material with a careful check of the part, load, temperature, pressure and surface condition before returning it to service.

COMMON QUESTIONS

Before You Apply

Use the answers below to decide whether this metal repair adhesive fits the part and repair conditions in front of you.

Can this repair adhesive replace welding on every metal repair?
No. It is a practical welding alternative for suitable cracks, casting defects and damaged fittings when welding access is limited. Adhesive repairs depend on the part, load, temperature, pressure and surface condition, so use professional repair or welding where the application demands it.
Will it work on cracks, sand holes and gas holes in castings?
Those are stated applications for the product. Clean away loose material, expose sound surrounding metal and press the mixed adhesive into the defect. Check the repaired part carefully before putting it back into service.
Can it be used around threaded metal fittings?
Yes, damaged threaded components are among the listed applications. Remove contamination, apply the mixed adhesive around the damaged area and keep the fitting out of service until the repair has properly set.
Is the repaired area waterproof after application?
Good waterproof performance is a stated product claim. The surface still needs to be clean and dry during application, and the repair must be suitable for the pressure and water conditions of the part.
How do I mix the two components correctly?
Use the included transparent mixing cups and spatula. Dispense the two components, mix them thoroughly according to the product directions and apply the gray adhesive to prepared metal. Do not guess the ratio or leave unmixed material.
Can I use it on a hot or pressurized part?
No. Isolate, depressurize and cool the part before application. High-temperature resistance refers to the stated property of the finished adhesive, not permission to apply it while the part is hot or under active pressure.
What comes with the 100ml cartridge?
The kit includes the metal repair glue cartridge, printed product box, mixing spatula and transparent mixing cups. Those included accessories add value over buying a basic adhesive alone.
