The Ultimate Scale Modeller’s Glue Guide: Which Cement or Super Glue Do You Actually Need?

If you are stepping into a hobby shop or browsing online for your next project, the sheer variety of adhesives on the shelf can be completely overwhelming. Do you need a thick liquid cement, a water-thin adhesive, or a high-strength super glue?
Using the wrong glue can lead to messy, frosted canopies, weak joints, or ruined plastic detail. Today, we are breaking down the absolute best glues in the hobby - including Tamiya, Revell, and Deluxe Materials Rocket - so you know exactly which bottle to grab for your workbench.

The Classic All-Rounder: Revell Contacta Professional

For generations of builders, Revell Contacta Professional has been a staple of the modelling desk. This is a traditional, slightly viscous (thick) liquid cement that comes in an iconic blue bottle with a fine hollow needle applicator.
 How it works: It works via a chemical reaction that melts the top layer of polystyrene plastic, welding the two pieces together into a single solid bond.
 Best used for: Large, structural joins that need maximum strength and a bit of "wiggle room" before the glue cures. It’s perfect for joining the two halves of a large aircraft fuselage or securing the heavy hull plates of a 1:35 scale tank.
 Pro-Tip: Keep a thin wire handy to unblock the metal needle if the glue dries inside it!

The Benchmark Standard: Tamiya Cement (White Cap)
Commonly known as "Tamiya White Cap," this is a medium-viscosity orange-scented liquid cement that comes with a small brush built right into the lid.
 How it works: Like Revell, it melts the plastic to create a weld. However, because it uses a brush rather than a needle, you apply it directly to the mating surfaces of the parts before pressing them together.
 Best used for: General assembly of sturdy parts, interior cockpit tubs, and bulkheads. It fills minor gaps naturally because of its slightly thicker consistency.

The Workbench Game-Changer: Tamiya Extra Thin Cement (Green Cap)
If you ask veteran modellers to name the one tool they cannot live without, Tamiya Extra Thin wins almost every time. This water-thin cement has completely revolutionized how modern plastic kits are built.
 How it works: Unlike traditional glues, you do not apply Extra Thin to the parts before joining them. Instead, you hold the two dry plastic parts tightly together, touch the ultra-fine brush to the seam, and the glue instantly draws itself deep into the joint via capillary action.
 Best used for: Crisp, modern toolings, delicate small parts, and long, straight seams (like airplane wings). Because it evaporates incredibly quickly, it leaves almost zero messy residue or fingerprint marks on your pristine plastic.

The Speed Demon: Tamiya Extra Thin Quick-Setting (Light Green Cap)
Taking everything loved about the original Extra Thin, the Quick-Setting variant is formulated to evaporate and cure roughly twice as fast.
 Best used for: Speeding up your build time on repetitive sub-assemblies, such as attaching dozens of individual tank track links, or holding tricky, springy parts in place that want to warp out of alignment.
 Take Note: Because it dries almost instantly, you have zero time to adjust the part once the glue touches it. If you need to slide a part into place, stick with the standard Green Cap.

When Plastic Cement Won't Work: Deluxe Materials Rocket Super Glues
Polystyrene cements *only* work on standard plastic-to-plastic joints. If you are building a premium multi-media kit that includes Photo-Etch (PE) brass detailing, resin conversion parts, or metal gun barrels, you need a Cyanoacrylate (CA) - commonly known as super glue.
The Deluxe Materials Rocket range offers specialized formulas depending on your exact build needs:
Rocket Heavy (Thick CA)
 The Blueprint: A high-viscosity, thick super glue that stays exactly where you put it without running.
 Best used for: Filling major structural gaps or bonding heavy resin upgrade parts to a plastic model hull. It cures slowly enough to let you perfectly align large components.
Rocket Rapid (Medium CA)
 The Blueprint: The ideal, fast-acting all-rounder for everyday multi-media modeling.
 Best used for: Attaching delicate photo-etch brass brackets to military vehicles, securing instrument panels, or bonding dissimilar materials together cleanly in 5 to 10 seconds.
Rocket Hot (Ultra-Thin CA)
 The Blueprint: An incredibly fast, water-thin super glue designed for precision.
 Best used for: Microscopic detailing. Just like Tamiya Extra Thin, you hold your tiny metal or resin part in place with tweezers and let Rocket Hot penetrate the joint instantly via capillary action. It cures almost immediately.
