Museum Putty and Adhesive Pads
Removable museum putty (also called earthquake putty or museum wax in various formulations) is a non-hardening, removable adhesive compound used by professional museums and galleries to secure display items against seismic movement. A small ball of putty (approximately 6 mm diameter, about the size of a large pea) pressed under the base of a figure creates a holding force that resists lateral movement without permanently bonding the figure to the shelf surface.
The putty works by conforming to both the figure base and the shelf surface, creating a contact-area grip that resists horizontal sliding forces. In a moderate earthquake, a figure secured with museum putty will typically move slightly but not fall; a figure without putty will topple from even minor vibration. The putty is removable — press and twist to release — without leaving residue on painted bases or shelf surfaces when used as directed.
For larger or heavier figures, use two putty points (front and back of the base) rather than one central point. The dual-contact approach resists both front-back and side-to-side movement. Reapply putty annually or whenever you move a figure — the putty loses holding strength gradually as it dries and should be replaced rather than reused.
Shelf Lips and Physical Barriers
A physical barrier at the front edge of a shelf is the most reliable passive protection against figure falls from seismic activity or vibration. A shelf lip of 15–25 mm height stops most standard-sized figures from sliding off during a moderate seismic event. This can be a built-in shelf feature, a strip of wood or acrylic glued or screwed to the shelf front edge, or a removable acrylic rail secured with double-sided tape.
For shelves that need to remain open at the front for aesthetic reasons, an invisible alternative is a 3 mm raised silicone strip across the full width of the shelf, 5 cm from the front edge. Figures sit behind it naturally, and the silicone's friction coefficient is high enough to dramatically reduce sliding distance during vibration. The strip is nearly invisible at display distances but provides meaningful mechanical resistance.
Acrylic display cases provide the most comprehensive seismic protection: a figure inside a closed acrylic case cannot fall off a shelf because the case itself is the enclosure. If the case slides, the figure remains protected inside. For this reason, fully enclosed cases are recommended for high-value figures in any region with seismic activity or for any display in a high-traffic home environment.
Anchoring Shelving Units to Walls
Securing the display shelving unit itself to the wall is as important as securing figures to shelves. An unsecured bookcase or display unit can topple during a significant seismic event, and when it does, the figures inside sustain combined impact from both the fall and the collision of shelves with the floor. Wall-anchoring a display unit takes 20 minutes with a stud finder and two L-bracket anchors and is required by building codes in many seismically active jurisdictions.
The anchor point should be through the unit's top structural member into a wall stud, not just into drywall. A drywall-only anchor provides insufficient resistance for a loaded shelving unit's rotational forces during shaking. If studs are not positioned where you need anchors, use a toggle bolt rated for the expected load — typically a 5–7 kg holding force per anchor is sufficient for preventing tip-over of a standard display unit.
Free-standing display cabinets with glass doors need both wall-anchoring and door latches that don't open under vibration. Magnetic door closures common on IKEA-style cabinets can open during sustained vibration, allowing figures to fall against the doors from inside. Replace magnetic closures with positive-click latches on any cabinet in a seismic zone — the latches engage mechanically rather than magnetically and won't release from vibration alone.
Case and Figure Weighting Strategies
The center of gravity of a display arrangement matters for earthquake resistance. Taller, heavier figures placed lower on a shelving unit and shorter, lighter figures placed higher reduces the system's tendency to become top-heavy and topple. Placing figure cases (which are heavier per unit than bare figures) on lower shelves while bare lightweight figures occupy higher shelves is both structurally smarter and aesthetically valid.
For very tall or slender figures with a narrow base-to-height ratio, a custom-fitted weighted base can be added: a piece of 6 mm steel plate or a heavy ceramic coaster beneath the figure significantly lowers its center of gravity and increases resistance to toppling. Weight the base, not the figure — adding internal weight to vinyl figures is not practical and risks damage.
After installing any seismic protection measures, test them by applying gentle lateral pressure to each figure or case by hand. You should feel resistance before movement begins. A figure that slides easily under light hand pressure will slide easily under seismic vibration. Test after each shelf rearrangement — museum putty loses contact when figures are repositioned, and it's easy to forget to re-apply.
