There is always a need to glue one object to another object. It is simple to glue things together of the same material and have them stick, but a bit more complicated if the objects consist of different materials. Once you know what glue works for each substance, your job becomes easier. If you have never bonded two different materials together, such as plastic to rubber, first try it on scraps similar to the materials that you will be working with to get an idea of how much glue you need to use.

Sand the plastic lightly with 12-grit sand paper to roughen up the surface. This will make the glue adhere easier to the smooth surface of the plastic. Wipe clean with a damp cloth and allow to dry.

Apply epoxy glue to the plastic with a brush or wooden stick.

Let the glue tack dry a minute or two.

Press the rubber to the plastic, applying pressure.

Wipe off excess glue from the plastic and rubber with a warm, wet sponge. Let the glued item set for two days to cure before handling.


Always have proper ventilation when working with glue.
