Gomagom 20 Modeling Adhesive 20ml | Scale Models, Dioramas and Models

GomaGom Modelling Adhesive 20 is the classic scale modeller's glue in a 20 ml tube — the tried-and-true choice for assembling plastic model kits of planes, cars, ships and military vehicles from brands like Revell, Tamiya, Italeri, Airfix, Heller, Hasegawa and Trumpeter, for building dioramas with wood and cardboard elements, and for craft models. Dries clear and fast-setting, it "welds" model plastic (HIPS polystyrene) and bonds wood, card, paper, foam board and mixed metal-to-wood joints. Not suitable for 3D printed parts or UV resin — for those materials we recommend cyanoacrylate or epoxy putty (see below for guidance on which to use).

Looking for a 3D printing adhesive? This isn't it

If you landed here looking for glue for 3D printed parts (resin or PLA), printed wargaming miniatures or 3D part repairs, here's what you need to know before buying: this adhesive is NOT for that. Its solvent-based formula (acetone and n-butyl acetate) attacks PLA and can damage finishes on UV resin parts.

For 3D printing, our GomaGom range has the right options for your needs:

• For assembling 3D printed parts (resin or PLA), miniatures and precision modelling: GomaGom Super Adhesive 9 with brush applicator — cyanoacrylate, the standard adhesive for 3D printing.
• For repairing broken 3D printed parts, filling gaps and conversions: GomaGom Epoxy Putty 31 — two-part formula that bonds and fills at the same time.
• For correcting misaligned joints or removing excess cyanoacrylate from printed parts: GomaGom Adhesive Remover 21 — dedicated debonder solvent.

If you're working on scale modelling, dioramas or traditional plastic kits, read on — you've found the right product.

What it's actually for

The solvent-based formula (acetone and n-butyl acetate) means this adhesive works well on two very specific material families:

Model plastic (polystyrene / HIPS). This is the plastic used in scale model kits from all the major brands: Revell, Italeri, Tamiya, Hasegawa, Airfix, Heller, Trumpeter and AMT. On polystyrene, the adhesive partially "welds" the surfaces together — it dissolves a very thin layer of the material, and as the solvent evaporates, the parts bond structurally rather than simply sticking surface-to-surface. This is the classic behaviour of traditional model kit glue.

Wood, cardboard, card and paper. For diorama bases with wooden elements (plinths, balsa sheet, plywood, MDF), technical boards such as foam board, and all paper and card craft work. Also works on mixed joints such as metal-to-wood.

For "other materials", as the manufacturer states on the label, specialist adhesives are recommended. This includes soft plastics (polyethylene, polypropylene), rubber, glass and ceramics, where results may be poor or the bond may not hold.

How to use it

Simple and straightforward:

1. Clean, dry surfaces. Free from dust, grease and support residue. On plastic kit parts freshly cut from the sprue, lightly sanding the contact surfaces will improve adhesion.

2. Apply a thin layer to one of the two surfaces. Using the tube nozzle. Avoid thick layers — they cure poorly, leave a visible seam and squeeze-out will mark plastic kit parts.

3. Join and leave to cure. Setting is fast, but hold the parts in position for a few seconds to prevent shifting. For joints that need full strength, it's best to wait until the following day before handling the model.

Important safety information. Liquid and vapours are highly flammable. Work in a well-ventilated area, away from flames or heat sources. Avoid prolonged skin contact — repeated exposure can cause dryness or cracking. Keep out of reach of children.

Diorama and Base Construction

Beyond scale model assembly, the GomaGom 20 is a versatile tool for the structural side of diorama building. It works well for bonding wooden sheets together (balsa, plywood), gluing foam board to wood, assembling structural bases, securing relief elements to the base (rocks, rubble, dried foliage) and joining technical card with texture paper.

An important note for modellers who work across disciplines: if your diorama includes painted miniatures or 3D printed parts, do NOT use this adhesive to attach them to the base — use cyanoacrylate for that. This glue is intended for the structural components of the diorama (wood, card, paper) only, not for the figures themselves.

About the Tube Contents

A note on transparency: the net contents legally declared by the manufacturer on the back of the packaging (marked with the ℮ symbol, the European nominal quantity indicator) is 20 ml. The front of the blister pack states "30 ml", which appears to be a print error by the manufacturer on that production run. We sell what the legal label states: 20 ml.

Why Buy from Mr Resin

Although Mr Resin specialises in 3D printing, we know that many modellers work across disciplines: a scale kit with added printed parts, a diorama with wooden bases and resin-printed minis, a conversion mixing Tamiya pieces with foam board scratch-building. We stock the right adhesive for every part of the build, so you don't have to shop around.

If you're already ordering resin, filament or paint, adding the GomaGom 20 adhesive ships in the same parcel at no extra cost. Orders over €79 ship free to mainland Spain.

Mr Resin has been serving over 5,000 makers across Spain, Portugal and France for years. Our catalogue is built around what the community asks for: printers and materials as the core, with the workshop consumables that end up being part of everyday life.

Frequently Asked Questions

Does it work for gluing Revell, Tamiya, Italeri or Airfix kits?
Yes. The vast majority of scale kits from these brands are made from polystyrene (HIPS), and this adhesive is specifically formulated to "weld" that plastic. The manufacturer's own packaging shows a slot car and a scale aircraft as typical use cases. For critical joints or very small parts, advanced modellers often prefer an extra-thin plastic cement such as Tamiya Extra Thin, but for general modelling use the GomaGom 20 performs more than adequately.

Can I use it on 3D printed parts?
No, we don't recommend it. The acetone in the adhesive softens PLA and can attack painted finishes on UV resin. For 3D printed parts, the standard adhesive is cyanoacrylate (super glue) — we carry the GomaGom 9 with brush applicator, which is ideal for that purpose. For joints that need gap-filling, the GomaGom 31 Epoxy Putty is the right choice.

Can it be used for building dioramas?
Yes, it works perfectly for the "structural" part of the base: wood sheets (balsa, plywood), foam board, card stock, texture paper, and combinations of these materials with metal elements. What you should NOT do is glue miniatures to the base with this adhesive — for that, use cyanoacrylate (the mini bonds better and there's no risk of attacking the paint).

Why does it smell so strong?
Because it's formulated with organic solvents (acetone and butyl acetate). This is what allows it to "weld" plastic model parts together, but it's also why you need to use it in a well-ventilated area. If you work with the window closed in a small room, you'll notice the fumes within minutes. Open a window, ventilate the space, and even better if you have a small extractor fan over your workbench.

Is it safe for children?
The label clearly states "keep out of reach of children" due to flammability and fumes. For children's crafts, we recommend using traditional white PVA glue (non-flammable, no fumes, water-washable). This adhesive is intended for adult modellers and hobbyists, in a ventilated area and with the precautions indicated on the packaging itself.
