By gluing together your LEGO construction projects, you can preserved them so they can be enjoyed for years. Through proper preparation and application, you can create a bond that is almost as strong as the bricks themselves. Use the glue sparingly and carefully will keep excess glue from squeezing out from between the LEGO bricks and giving the finished model a sloppy look.

Skill level:

Things you need

  • Isopropyl alcohol
  • Cotton swabs
  • Paper towel
  • Super glue
  • Wood toothpicks

  1. 1

    Open the isopropyl alcohol and pour a few drops into the lid in a well-ventilated area.

  2. 2

    Dip the end of a cotton swab in the isopropyl alcohol in the lid until it is saturated.

  3. 3

    Wipe down the surfaces of each LEGO brick with the alcohol soaked swab where it will come into contact with the other bricks.

  4. 4

    Place the cleaned LEGO bricks on a steady flat surface that has been covered by a paper towel.

  5. 5

    Squeeze a small bead of super glue onto the tip of a wooden toothpick and apply it in a thin layer to the tops and sides of each bump on the top of the brick.

  6. 6

    Snap the bricks together firmly and allow the super glue to dry for at least 20 minutes with the connected LEGO pieces sitting straight up so they will not stick to the paper towel.

Tips and warnings

  • It is best to err on the side of too little glue. You always can add glue and reset a piece that comes apart.
