Glue aluminum - that's how easy it is

Glue aluminum - that's how easy it is: easy

Aluminum is relatively soft and stretchy, so it's easy to work with - even slides can be made from it. Since aluminum has a low density and weighs only about one third of the weight of steel at the same volume, it is often used for the construction of aircraft but also for parts of railway cars or cars. At the same time, it conducts heat very well and is therefore also used in cooking appliances and packaging.

Aluminum can be welded. However, this is of little relevance to household repairs. It is more important for this purpose that you can glue aluminum. How that works is shown here.


  • Grease-dissolving cleaner
  • Sandpaper, grain size 80 or 100
  • Two-component acrylate adhesive or one-component assembly adhesive

Glue aluminum: Two methods

1. Stick aluminum to aluminum

Glue aluminum - that's how easy it is: adhesive

Before the adhesive application, the aluminum thoroughly cleaned with a degreasing cleaner.

In the first step, you must thoroughly clean and degrease the surfaces to be bonded. A greasy film, but also loose dirt would act as a release agent and prevent the adhesion of the adhesive. In addition, roughen the surface with 80 or 100 grit sandpaper and dedust it carefully.

The connection you set with a Two-component adhesive which is suitable for gluing aluminum. Observe the processing time (pot life) and the curing time until the adhesive has reached its final strength. Both are specified by the manufacturer.

2. Bond aluminum with other metals or with non-metals

After the adhesive surfaces have also been prepared as above, apply the assembly or construction adhesive according to the manufacturer's instructions. Pay attention to a uniform, full-surface bonding - It often makes additional sealing unnecessary.
