Metal bonding adhesives have revolutionised the way we repair and complete projects, although even with such a great product, not being used correctly can still result in failure. We track five missteps you can make and show how to avoid them for predictable performance.
- Skipping Surface Preparation
Clean, dry and coarse surfaces are necessary for bonding to be effective in this material. Failure to clean or sand will leave oils and debris on the surface that would prevent a good bond. Always degrease and lightly key the metal before bonding.
- Using the Wrong Adhesive
There are different adhesives for different tasks. A universal glue that hasn’t been designed for specific use with metal may lack the strength and or endurance required. Use a recommended metal bonding adhesive only and test the compatibility of adhesives with your metals prior to coating.

- Misjudging Cure Time
It can be tempting to rush this and move on with the next step, but adhesives need time to properly cure. Bonded parts that are manhandled early compromise their strength. Always read the manufacturer recommended cure time, even if it feels too long!
- Overapplying
More isn’t always better. Too much glue can squeeze out and be messy, too little will not hold. The more evenly you can apply it, the better.
- Ignoring Safety Precautions
Some adhesives contain strong chemicals. Gloves should be used, the atmosphere must not contain a lot of dust and products have to always stored safely.
Stay away from these pitfalls, and you will provide stronger bonding to your metal every time.
