It's easy to glue acrylic plastic. (plastic frame image by Ivan ivashin from

Durable, easy to maintain and used in residential and commercial settings, acrylic is a clear plastic often used in place of glass. The material is also used to make displays and shelving. Like other plastics, acrylic pieces can be glued together using an adhesive designed for acrylic. Before gluing pieces of acrylic, you need to clean the material to remove any dust and other debris from its surface. Debris can become embedded in the glue and can also scratch the acrylic's surface.

Skill level:

Things you need

  • Newspaper
  • 2 soft, nonabrasive cloths or rags
  • Sandpaper: 240-grit or higher
  • Latex gloves
  • Isopropyl alcohol (99 per cent)
  • Plastic syringe: 15ml with a 1-1/8 inch tip
  • Acrylic glue
  • Straight pins
  • Nose mask (optional)

  1. 1

    Place two to three pieces newspaper onto a flat surface--workbench, desk, countertop or other surface.

  2. 2

    Wipe the acrylic pieces you want to glue with a soft, nonabrasive cloth or rag to remove any loose dust or debris from the pieces. Wear latex gloves to keep your hands clean.

  3. 3

    Sand the ends of the acrylic you want to glue together with a piece of 240-grit or higher sandpaper. Sand until the ends are smooth and flat. The ends should not be rough or curved.

  4. 4

    Place the pieces of acrylic together you want to glue to see how the pieces fit. The pieces should fit together smoothly, if not, repeat Step 3.

  5. 5

    Apply 1 tbsp of isopropyl alcohol to a soft, nonabrasive cloth or rag. Wipe the acrylic pieces with the alcohol-soaked nonabrasive cloth or rag to remove any sand dust and debris. Re-apply alcohol to the cloth or rag, if needed.

  1. 1

    Fill a 15ml plastic syringe with 1 tbsp of acrylic glue. Squeeze the glue from the syringe onto the first piece of acrylic you want to glue.

  2. 2

    Place two or more straight pins evenly onto the area containing the glue. Place the pins so they can be pulled away from the acrylic. The pins provide a gap between the two pieces so air bubbles won't form.

  3. 3

    Place the second piece of acrylic flush with the first piece of acrylic. Let the two pieces sit for one minute and form a bond.

  4. 4

    Remove the pins from the glued acrylic pieces. Push the two pieces together. You will notice excess glue pushing out from the two pieces---this is OK.

  5. 5

    Let the joined acrylic pieces dry for one hour before handling the pieces.

Tips and warnings

  • The longer you let the joined acrylic pieces dry, the better.
  • If you notice a small gap between the two joined acrylic pieces after the pieces are dry, you didn't sand the ends properly, fill the gap with acrylic glue and let the glue dry before handling the joined pieces again.
  • Acrylic glue is toxic, dangerous and does have a smell. Work in a well-ventilated area and if the smell bothers you, wear a nose mask.
  • Avoid getting the acrylic glue on your hands and skin.
