Metal comes in many different types and styles. One of the common forms of metal is sheet metal, which comes in many sizes. Acrylic is a type of clear plastic that's similar to a piece of glass and is used for most of the same applications. Acrylic is much stronger than glass and is also slightly flexible. Often times, acrylic and metal may have to be joined. Joining them only involves a few tools and a little bit of time.

Instructions

  1. 1

    Set both the acrylic and metal on a flat and steady surface. Set one on top of the other and verify that they're the desired size you want before attaching them together.

  2. 2

    Sand down the surface of the metal with 240-grit sandpaper. Go over the entire side you will be joining with the acrylic in a smooth and circular motion. Start at one corner and work to the other until the surface is smooth and even throughout.

  3. 3

    Wipe off any grit or other debris left over from the sandpaper with a clean rag. Pour a small amount of isopropyl alcohol onto a clean rag and wipe down the metal surface. Remove all dust and oil on the surface and wipe off all the alcohol with a clean rag.

  4. 4

    Lay both pieces down flat on the surface, one next to the other with the sides that will be attached facing up. Spread out a thick 1/4-inch bead of epoxy over the entire surface of the acrylic. Start 1 inch from any corner and work around the surface until you reach the starting point.

  5. 5

    Set the metal down on top of the acrylic and hold it in place for five minutes. Run your hands over the entire surface so that the epoxy can adhere to both the acrylic and metal. Wait at least four hours for the epoxy to set before moving the metal and acrylic.
