An epoxy glue will be able to permanently bond rubber to aluminium if done correctly. This may be helpful when performing renovations in your home or when making a piece of art that contains both rubber and aluminium.
Wash the aluminium where it is to be glued with mild soap and water. This will remove any dirt or oil that exists on the aluminium. Thoroughly dry the aluminium with a rag when washing is complete.
Sand and rub the area of the aluminium that is going to be glued to the rubber. By sanding the area, you are giving the glue a better chance of strongly adhering to the aluminium. When done sanding, rinse off all of the metal dust that is left. Wipe the rinsed area dry with the rag.
Squeeze the epoxy glue onto the aluminium where you sanded it. A few drops is all that is needed as it should be spread to evenly cover the sanded surface.
Place the rubber on the aluminium surface where the epoxy glue is. It can be held in place with a workbench clamp or masking tape to ensure that it does not move. If using a clamp, place a thin block of wood on the backside of the aluminium.
Epoxy glue emits fumes and should only be used outside.
