How to Glue Legos Together

The Lego company began in Denmark in 1932 and now sells Lego in over 130 countries. Estimates say kids around the globe collectively spend over 5 billion hours a year playing with Lego. While Lego models are designed to be assembled and then taken apart sometimes kids, or adults, wish to preserve the completed model. Lego models can be glued together, allowing them to be moved more easily and enjoyed longer.

Assemble your model to ensure you have all the pieces and the finished model looks the way you desire.

Place the model on a flat surface where it can remain undisturbed while the glue dries. Begin removing layers of Lego pieces from the model, keeping them in the order they were originally placed.

Apply a tiny drop of glue to the top protrusions of one Lego piece. Connect to the next Lego piece and press firmly in place 2. Ensure the pieces are tightly connected with no gaps between bricks. Excess glue can keep pieces from firmly seating with the next piece, causing misalignment to occur after several layers. Wipe away excess glue from the face of any pieces with a damp cloth.

Continue the process of adding layers and gluing the individual pieces together until the model is reassembled.

Allow the glue to dry completely - read the instructions on the glue for required drying time - before attempting to move the model.


All purpose cement for PVC, ABS and CPVC pipes works well for gluing Lego pieces together.

Large models may take several hours to completely glue together. Resist the urge to hurry the process.


Professional Lego model builders use solvents such as methyl ethyl ketone to glue Lego pieces together, which produces dangerous fumes. There are less toxic adhesives for general use.
