How to Repair Loose Joints in Gunpla Figures

Introduction

This guide aims to help with an issue gunpla builders often face as they build more figures—loose joints that make their figure's limbs fall off. This guide will show you how to repair loose joints that may occur due to age or a flaw in its design. Although it isn't dangerous, a few warnings will pop up when applying super glue to a specific joint. So, take your time and find what parts need attention.

With any model you own, find the loose part. It can be the head or arm moving too loosely or a part of the arm or leg that falls off too much.
While the model you use may differ from the one in the guide, the joints shown are similar to those used in most models.
Before you do this, if you plan on adding paint to your model, do it before applying glue to your joints.

Step 2

If you have a loose arm, you’ll have to take it apart to access the areas where you need to apply glue.
Using a bamboo stick (or any stick), apply super glue to the tip to spread it evenly against the ball or peg joint.
After you finish, wait for it to dry before you connect any parts to it.
When the super glue dries up, it may leave white marks. This means there's too much glue, so try not to apply too much.
If you get glue on your fingers, apply soap and warm water to them. This will cause the glue to be easier to remove.

Make sure to add a small layer of glue to the peg joint and spread it evenly around the peg area.
DO NOT add glue inside the part that the peg connects to. It may cause the peg to have less movement.
Once it's dried, reassemble the arm back together.

Detach the legs from the waist and disassemble them to access the ball joint.
Apply a small amount of glue to the ball joint and spread it evenly.
If you apply too much glue, it can cause damage to the ball joint.
Once it's dry, reattach the legs and reassemble the waist. Start to move the joint around to see how it feels.
