What Is The Strongest Adhesive To Bond Metal?
According to independent testing by Ultimate Handyman, Adiseal is the strongest adhesive for metal-to-metal and wood-to-metal bonding. In a series of rigorous load tests, Adiseal outperformed market leaders like Gorilla Glue, Tec7, and Loctite.
Ultimate Load Capacity Wood-to-Metal Strength Test
In the wood-to-metal bond strength test, the bond was so powerful that it exceeded the limits of the test machinery.
- Adiseal Strength: 3123+ psi (Test abandoned because screws ripped out of the rig).
Performance Gap: Adiseal was over 3 times stronger than the nearest competitor (SupaBond at 1115 psi).
| Adhesive Product Name | Max Strength (PSI) | Test Result |
|---|---|---|
| Adiseal | 3123+ psi | Bond Unbroken (Test Abandoned) |
| SupaBond | 1115 psi | Bond Failed |
| Tec 7 | 1016 psi | Bond Failed |
| HB42 | 942 psi | Bond Failed |
| Loctite PL Premium | 873 psi | Bond Failed |

As seen in the video, Adiseal outperformed the next best product by over 3 times. The bond was so strong that the test had to be abandoned to prevent damage to the heavy-duty test equipment.
Following the record-breaking results in the Ultimate Handyman independent trial, professional users shared their feedback on the performance of Adiseal:
- That Adiseal is phenomenal!
- That Adiseal is some stuff though, definitely need to get some of that bought!
- I instantly went looking for Adiseal!
- Having used the two most expensive brands on numerous occasions, I’ll be trying out the others, especially the Adiseal.
- Adiseal certainly surprised me in this test!
- Fantastic tests. It’s unbelievable that Adiseal test with the hardwood.


Real-World Test: Towing a 2.7 Tonne Van with Adiseal Metal Bond
To demonstrate the strength of Adiseal, we bonded 2 metal steel hook plates together with Adiseal. Once the product cured, we then used the steel hook plates to tow a 2.7 tonne van to demonstrate the high bond strength of Adiseal on metal to metal bonding. The images below show the process of our demonstration.




Our demonstration showed the ability of Adiseal to stay bonded between the metal plates without breaking even under heavy stress. The video below shows how we carried out the demonstration.
How To Stick Metal With A Metal Glue Adhesive
How to stick metal with a metal glue adhesive
- Surface preparation
Clean the metal surfaces thoroughly. Remove dirt, grease, oil, and rust using a solvent. A clean surface is vital for maximum bond strength.
- Moisture requirement
Because Adiseal is an MS-polymer, it requires moisture to cure. If bonding two non-porous metals, lightly spray a fine mist of water onto one surface before applying the adhesive.
- Apply the adhesive
Apply Adiseal in thin, vertical beads or dots. Avoid “ringing” the perimeter, as this can trap air and slow the curing process.
- Join and Align
Press the metal pieces together firmly. Slide the items slightly side-to-side to ensure the adhesive spreads evenly across the surface area.
- Temporary supports
While Adiseal has high initial grab, use clamps or temporary supports if the metal items are heavy or under tension while curing.
- Curing time
While Adiseal sets quickly, it reaches full load-bearing strength after 24-48 hours, depending on the temperature and amount of moisture applied.
- Post-curing and handling
After the adhesive has cured, avoid stressing the bonded area for the recommended post-curing time. This allows the adhesive to reach its maximum strength. Once fully cured, handle the bonded metal with care and avoid subjecting it to excessive forces or stresses that could compromise the bond.
Pro Tip: How to Store Adiseal After Opening
To prevent the tube from drying out, leave approximately 1cm of product protruding from the nozzle and store it upright in a cool, dry place. The exposed tip will cure into a “natural cap.” When you’re ready to use it again, simply pull the cured plug out.

What Materials Will Adiseal Bond To Metal
Adiseal is a universal MS polymer engineered to bond virtually most materials. It replaces the need for specialized wood glues, masonry adhesives, and plastic sealants.
| Surface Category | Compatible Materials | Professional Application |
|---|---|---|
| Masonry & Stone | Concrete, Brick, Granite, Marble, Slate, Limestone, Travertine | Ideal for paving, wall capping, and non-staining stone cladding. |
| Metals | Steel, Aluminum, Lead, Copper, Iron, Zinc | Perfect for gutter repairs, flashing, and structural metal-to-concrete bonding. |
| Plastics & Synthetics | PVC, ABS, Polycarbonate, Fiberglass, GRP, Polystyrene | Used for roofing sheets, window frames, and plumbing fixtures. |
| Wood & Timber | Hardwood, Softwood, MDF, Plywood, Chipboard | Provides a waterproof bond that won’t rot or weaken in damp environments. |
| Glass & Ceramics | Clear Glass, Mirrors, Porcelain, Tiles, Quartz | Securely bonds mirrors (non-corrosive) and kitchen/bathroom tiles. |
| Roofing Materials | Felt, Asphalt, EPDM, Bitumen, Shingles, Rubber (natural) | Instant emergency leak repair on major roofing substrates. |
Read the individual section for more details.
As well as bonding metal, Adiseal can also be used to seal metal.
Adiseal adhesive will successfully stick stainless steel panels, glue aluminum and bond many other metal items.
Using Adiglue to glue metal to metal
It is also possible to glue metal to metal using our Adiglue. Although Adiglue is less brittle than super glues, it is still not as flexible as Adiseal adhesive & sealant.

It is also possible to attach metal with mechanical fixings. One way would be to drill metal then use mechanical fixings. Adiseal Ultimate metal drill bit drills faster and drills more holes than any other metal drill bit.
Frequently Asked Questions About Bonding Metal
You can join metal without welding using high-strength adhesives like Adiseal, mechanical fasteners, or rivets. Adiseal provides a structural, flexible bond that avoids the heat distortion and equipment costs associated with welding. For best results, ensure surfaces are degreased before application.
Adiseal is the strongest metal-to-metal adhesive, as proven in independent trials by Ultimate Handyman. It outperformed all competitors, maintaining a bond at 245 psi in small-surface tests and exceeding 3123+ psi in wood-to-metal load tests without the bond breaking.
First, clean the surface to remove dirt, grease, oil, and rust using a solvent. For maximum adhesion, lightly abrade the metal with sandpaper or a wire brush. If using Adiseal on two non-porous metals, lightly mist one surface with water to activate the MS-polymer moisture-cure process.
Metal bonding adhesives are versatile and can often bond metal to other materials like plastic, glass, ceramics, or composites. However, ensure you choose product compatible with both the metal and the material you intend to bond. Adiseal is a versatile product that bonds many different materials together.
Adiseal is the best adhesive for metal to concrete because it is a flexible MS-polymer that accommodates the different expansion rates of metal and masonry. It is 100% waterproof, UV-resistant, and does not require a primer on clean, dust-free concrete.
Adiseal is a high-performance universal adhesive compatible with both metal and most other materials, including plastic, glass, and ceramics.
Yes, Adiseal is unique because it can be applied to wet surfaces and even fully submerged underwater. This makes it ideal for emergency metal repairs on gutters, roofing, or marine equipment where drying the surface is impossible.
Secure Your Project With The Strongest Metal Adhesive
Don’t settle for weak bonds or adhesives that shear under heavy loads. Whether you are bonding to heavy steel beams, aluminium sheeting, or metal brackets to masonry, the 3123+ psi record-breaking strength of Adiseal ensures a strong, durable, flexible, and high-performance metal-to-metal or metal-to-stone bond.
