Understanding Citadel Plastic Glue

How to Open Citadel Plastic Glue -
Citadel plastic glue, manufactured by Games Workshop, is a modeling adhesive designed specifically for use on plastic miniatures and models. It is often referred to as “poly cement” because it works by partially dissolving the plastic pieces and fusing them together once cured.

Unlike regular white glues that dry through evaporation, Citadel plastic glue undergoes a chemical reaction with the plastic to create an extra strong bond. It is specially engineered to work with polystyrene and ABS plastics used in Warhammer figurines.

Key benefits of this glue include:

  1. Creates an unbreakable bond between plastic pieces
  2. Dries completely clear without leaving residue
  3. Sets and cures rapidly, speeding up assembly
  4. Allows repositioning of parts briefly before drying
  5. Thin consistency allows precise application

Due to its unique properties and performance, Citadel plastic glue has become an essential tool for Warhammer 40k hobbyists. However, the glue’s thick plastic tube and tightly affixed metal tip can make it very difficult to open the first time. Let’s look at what you’ll need to safely open it.

Total Time: 10 minutes

Put on Thick Gloves

Put on Thick Gloves

The first step is to protect your hands by donning thick, rubber gloves. Citadel plastic glue can irritate skin and the gloves will improve your grip.

Secure the Tube

Hold the tube upright in one gloved hand. Use your thumb and forefinger to steady the tube at its lower end, away from the applicator tip.

Grip Cap with Pliers

With your other hand, take a pair of small pliers and carefully grip the ridges of the metal cap surrounding the applicator tip.

Twist Cap Slowly

Once you have a firm grip on the cap with the pliers, gently twist it counter-clockwise to loosen and unscrew the cap.

Remove Cap

Continue firmly but slowly twisting the cap until it releases from the tube with a soft popping sound. Pull it fully off.

Snip off Tip End

Snip off Tip End

Use sharp snipping pliers or scissors to trim 1-2mm from the end of the applicator tip. This will widen the opening.


  • Citadel Plastic Glue Tube – The tube you are trying to open. Verify it is unopened and the desired cement.
  • Cloth or Paper Towels – For wiping up any excess glue.
  • Needle or Pin – For piercing the applicator tip to widen the opening.


  • Thick Gloves – To protect your hands and improve grip.
  • Small Pliers – Can aid in gripping and twisting off the cap.
  • Well-Ventilated Workspace – To avoid breathing in fumes.

Materials: Snipping Pliers or Sharp Scissors – For safely cutting open the tip. Waste Container – For discarded tips, residue, and paper towels.

By following these steps methodically, you should be able to open even the most tightly sealed Citadel plastic glue tubes. The key is using proper pliers for grip and twisting slowly but firmly. Widening the applicator opening will allow the thin cement to flow freely.

Tips for Using Citadel Plastic Glue

Once open, Citadel plastic glue can be used to assemble miniatures made of polystyrene, ABS, and other plastics. Here are some tips for getting the most out of it:

  1. Only use a tiny amount – a small drop is sufficient for most connections.

  3. Press parts together fully and hold for 10-15 seconds.
  4. Support the joint with modeling putty as it cures for extra durability.
  5. Let it dry completely – about 5 minutes or more, depending on humidity.
  6. Store upright with the cap securely closed to prevent clogs.
  7. If clogged, use a fine wire or needle to clear the applicator opening.
  8. Avoid getting glue on your fingers to prevent accidental bonding.

Frequently Asked Questions

If you’re new to Citadel products, you probably still have some questions about opening and using their iconic plastic glue. Here are answers to some of the most common questions hobbyists have:

Q: How do I know if the glue tube is sealed?

A: Look for an unbroken circular ring around the base of the applicator tip. Avoid buying tubes where this ring is cracked or peeled away.

Q: Can I just cut the applicator tip with scissors?

A: It’s best to twist off the cap first, then trim just 1-2mm from the existing tip opening. Cutting too much can damage the applicator.

Q: What if I can’t get the cap to twist off?

A: Make sure you are slowly twisting counter-clockwise. Use pliers or a rubber gripper for better leverage. The seal is quite tight.

Q: Is there a trick to getting the cap off?

A: Some hobbyists have had success placing the ridged cap between their teeth to get enough grip to pop the cap loose and unscrew it.

Q: How long does Citadel plastic glue last if I leave the cap off?

A: The opened glue will begin drying out within an hour or two if left uncapped. Always close it tightly after each session.

Q: Can I use the glue if the applicator tip is clogged?

A: You can try piercing the clogged tip with a pin or wire. If still blocked, the applicator may need to be replaced.

Q: How do I prevent the glue from drying inside the tube?

A: Never return unused glue from the model or palette back into the tube – this accelerates drying. Keep the tube upright with cap sealed to prevent leaks.

Q: Is it toxic if I get it on my skin?

A: While not highly toxic, skin contact can cause irritation, itching, and redness. Wash hands immediately after use and wear gloves when applying.


Opening and using Citadel plastic glue doesn’t have to be intimidating, even on your first try. Follow this guide’s step-by-step instructions closely, utilize the recommended tools, and refer back to the tips if you encounter any issues.
