What is the best glue for plastic models? To properly assemble plastic parts with fine and precise joints, a very fluid glue specially designed for model making is often the most suitable solution.
For this type of assembly, SUPER GLUE Colle21 EXTRA THIN CEMENT – 30 ml, developed with AMMO by Mig Jiménez, is particularly interesting. Its very fluid formula penetrates the joints through capillarity, while its fine brush allows you to work with precision on small parts and delicate assemblies.

Why use Extra Thin glue for a plastic model?
A plastic model often includes very fine assemblies: fuselage, bodywork, hull, wings, turret, panels or small parts.
Glue that is too thick can create excess thickness or overflow around the parts.
The SUPER GLUE Colle21 EXTRA THIN CEMENT On the contrary, it is designed to penetrate tight joints and make clean assemblies. Its ultra-fluid formula and integrated brush allow particularly precise application.
It is particularly suitable for:
- polystyrene models;
- miniature planes, vehicles and armored vehicles;
- boats and hulls;
- large, perfectly fitted pieces;
- thin joints;
- small plastic elements.
How to use plastic model glue?
To obtain an accurate bond:
1. Make a blank edit
Position the two pieces without glue to check their fit.
2. Hold the pieces together
Align the elements correctly.
3. Apply a small amount of SUPER GLUE Colle21 EXTRA THIN CEMENT
Pass the brush at the joint: the very fluid glue is distributed naturally in the space between the pieces.
4. Hold for a few seconds
Avoid moving the assembly while setting.
5. Let dry before sanding or painting
👉 To remember:
adjust → maintain → apply in the joint → leave to act → dry
Why is capillarity interesting in modeling?
The capillarity allows a very liquid glue to naturally penetrate into an extremely thin space between two already positioned parts.
This avoids having to completely cover the surfaces with glue before assembly.
For the model maker, this allows in particular:
- to use very little product;
- to better control the application;
- to reduce overflows;
- to achieve fine joints;
- to obtain a more discreet assembly.
This is one of the main advantages of glue Extra Thin for plastic models.
EXTRA THIN CEMENT or SUPER GLUE cyanoacrylate?
The two products do not have exactly the same role.
To assemble two perfectly fitted plastic model parts, the SUPER GLUE Colle21 EXTRA THIN CEMENT is particularly interesting.
On the other hand, to stick metal, photoetched, certain resin parts or several different materials, a cyanoacrylate SUPER GLUE Colle21 may be more suitable.
The choice of glue must therefore always depend on the material and type of assembly. This is also an important point noted in specialist guides on model making glues.
Mistakes to avoid on a plastic model
To obtain a clean result, avoid:
- using too much glue;
- to pass the brush several times unnecessarily;
- touch the area with your fingers while taking it;
- to apply the glue before checking the fit;
- automatically use the same glue for plastic, metal and resin;
- handle or sand the part immediately after gluing.
With Extra Thin glue, precision matters more than quantity.
