Gomagom 32 PowerTack 20g | Reusable Adhesive Putty "Blu-Tack" Style for 3D Figures and Miniatures

Gomagom 32 PowerTack Exterior is a reusable adhesive putty in red square portions, 20 g, combining two properties that make it particularly useful for 3D printing workshops and scale modeling: 3 times stronger than standard adhesive putties (like the classic blue Blu Tack) and water and UV resistant, so it holds up under conditions that would cause a standard soft adhesive to fail. Peel it off, knead it with your fingers, press it wherever you need to secure something, and it stays put until you decide to remove it — leaving no residue and reusable dozens of times. Perfect for miniature painting, holding printed parts during post-processing, or home and office tasks that require temporary fixing without drilling or damaging surfaces.

Why miniature painters choose this putty

Anyone who paints wargaming miniatures (Citadel, Vallejo, Army Painter, or their own 3D prints) has been using Blu Tack-style adhesive putty for years. It's the standard way to mount a miniature on a painting handle, hold a small piece while painting it separately, or create temporary airbrush masks. The problem with traditional Blu Tack is that it breaks down with spray primer, varnish, and moisture, leaves residue on painted pieces, and can't support the weight of large busts or dense resin-printed terrain.

Gomagom 32 PowerTack Exterior solves all three problems: the exterior-grade formula resists water, isopropyl alcohol (used for washing UV resin prints), aerosols, and UV exposure without degrading. And being 3x stronger than standard Blu Tack, it holds pieces with real weight — a 75 mm bust printed in dense UV resin, large modular terrain, a 28 mm scale wargaming helmet, and more.

Use cases in miniature painting and 3D printing

Mounting miniatures on DIY painting handles. Press a small ball onto a wine cork, a wooden dowel, or a commercial painting handle. The miniature stays secure throughout the entire session and comes off cleanly when you're done. Reusable: the same piece works for dozens of different miniatures.

Holding small parts for separate painting. When assembling a kit in sub-assemblies before painting (shields, backpacks, weapons, heads, accessories), PowerTack lets you fix each piece to a holder while you paint it, without touching it with your fingers.

Temporary airbrush masking. To cover areas you don't want painted (a miniature's face while painting the armor, a gold area while painting the rest), apply PowerTack and peel it off once done — it withstands standard hobby aerosols without dissolving.

Propping printed parts during curing. To hold a freshly glued piece in a position it can't support on its own while cyanoacrylate or epoxy putty sets. Especially useful when assembling 3D printed parts with angled or irregular contact surfaces.

Securing UV resin prints during post-processing. To fix a piece to the work surface during sanding, support removal, or painting, without the risk of clamp deformation. Handles isopropyl alcohol from washing and uncured resin residue better than standard Blu Tack.

Miniature and model photography. To hold a piece in exactly the position you want to photograph, with no visible support. A minimal amount hidden behind the base solves the problem.

Other uses: home, office, and DIY

Beyond the world of miniatures and 3D printing, PowerTack fills the classic role of reusable adhesive putty, with the added benefit of its exterior-grade durability:

Hanging posters, photos, and signs. No nails, no pins, no wall damage. Perfect for rental spaces or any surface you don't want to mark up. Its UV resistance means it holds better than standard adhesive putty in areas with direct sunlight.

Securing items in garages, workshops, or humid environments. Where regular adhesive putty would eventually fail. Great for hanging labels, laminated instructions, 3D printer build plates, and parameter cheat sheets next to your equipment.

Quick fixes and temporary holds. When you need something to stay put for a few hours or days but want a clean, residue-free removal. Far neater than double-sided tape for temporary applications.

How to Use

The manufacturer's process is straightforward:

1. Peel off the amount you need and roll it into a ball. PowerTack comes in pre-scored square portions — peel off as many as you need based on the size of what you're mounting. A single portion is enough for small miniatures; for heavier applications (large busts, terrain pieces), combine several portions together.

2. Knead with your fingers until the putty is warm and pliable. The heat from your hands softens it and improves initial adhesion.

3. Apply to the back of the object and press firmly. Initial tack is immediate, but maximum holding strength builds over time — the manufacturer states this explicitly: "Adhesive qualities increase with time."

4. To remove: gently twist the surfaces apart. Do NOT pull straight off. The twisting motion breaks the bond cleanly without leaving residue on non-porous surfaces.

Important: surfaces where PowerTack should NOT be used. The manufacturer explicitly advises against use on absorbent surfaces (porous foam board, paper), delicate finishes, or surfaces that are wet, dusty, or freshly painted. Before using on a prized painted miniature, we recommend testing on a hidden area first — PowerTack has a strong hold, and on fragile or very recent paintwork it may lift paint when removed.

Lifespan and Storage

The putty is reusable across many cycles. Actual lifespan depends on use: if you're using it to hold miniatures for painting and it only contacts clean, dry surfaces, it can last months or over a year. If it's used in applications where it picks up dust, paint residue, or fine particles, the surface gradually becomes contaminated and loses grip — in that case, peel away the outer layer with your fingers to expose a fresh active surface, or discard that portion and use a new piece from the pack.

Store at room temperature in a dry place. It leaves no residue on non-porous surfaces, but always remove with a twisting motion to avoid any marks after extended contact.

Why Buy It from Mr Resin

If you paint wargaming miniatures or 3D printed parts on a regular basis, a sheet of PowerTack is one of those consumables that lasts a long time and solves problems every day — from the painting session to photographing the finished piece. Standard blue Blu Tack works up to a point, but it breaks down with the first coat of primer spray and can't hold heavier pieces. The EXTERIOR version of the Gomagom 32 handles those demanding situations.

If you're already ordering resin, filament, or paint, adding the PowerTack ships in the same package at no extra cost. Free shipping to mainland Spain on orders over €79.

Frequently Asked Questions

Can I use it to attach miniatures to a painting handle?
Yes, this is one of its best use cases. A small portion on top of a cork or commercial holder is enough to secure a miniature throughout an entire painting session. The bond holds through hours of handling, and the figure releases cleanly when you're done — no residue left behind as long as you remove it with a twisting motion. The key advantage over standard Blu Tack is that it holds up to primer and varnish sprays without losing its grip.

Is it compatible with primer and varnish sprays?
Yes. As an outdoor-formula putty with water and UV resistance, it also withstands the aerosols commonly used in miniature painting: spray primers, matte/satin/gloss varnishes, and lacquers. Where standard Blu Tack absorbs moisture from the spray and loses its hold, PowerTack maintains adhesion throughout. This makes it particularly useful as a temporary mask for airbrushing.

Can it hold the weight of a large miniature or resin-printed terrain piece?
Yes, within a reasonable range. The manufacturer rates it at 3× the adhesive strength of standard putty, which in practice means it can securely hold dense UV resin busts at 75 mm scale, medium-sized modular terrain, and 28–32 mm scale miniatures without issue. For very heavy pieces (large busts over 200–300 g, plaster-based dioramas), we recommend using multiple portions combined or switching to mechanical fastening.

How many times can it be reused?
Dozens of times, depending on how it's used. If it only comes into contact with clean surfaces (washed hands, dust-free miniatures, dry supports), it can last months or even over a year with regular use. If it picks up dust or paint residue over time, the surface becomes contaminated and gradually loses its grip — in that case, simply peel away the outer layer with your fingers to expose fresh putty underneath.

Does it leave marks or residue on painted miniatures?
On properly painted surfaces with a fully cured finish (well-dried acrylics, fully set primer), it leaves no residue as long as you remove it with a gentle twisting motion rather than pulling straight off. On very fresh or fragile finishes (paint applied the same day, partially cured varnish), there is a risk of lifting paint. As a general rule: make sure the miniature is fully dry before applying PowerTack, and test on a hidden area first if the piece is valuable.

Can it be used with 3D printers?
In the literal sense — securing prints to the build plate or shimming the FEP — it's not recommended: there are purpose-built products for those applications. Where it does work very well is in post-processing: holding printed parts to your work surface while sanding, removing supports, or painting, without the risk of deformation that a clamp might cause. It's a workshop tool, not part of the printing process itself.
