Spray Foam Sealant

A thick, expanding synthetic foam erupts from a handheld applicator, rapidly solidifying to plug breaches in the space liner's corroded bulkheads. The foam hisses as it cures, its pale yellow texture contrasting with the charred metal of the corridor walls. Kari and Olvir wield these canisters with military precision, directing streams into widening fractures to buy critical time. The foam’s acrid chemical scent mixes with the acrid tang of ozone from smoldering wiring, its application marking the difference between structural collapse and fleeting survival.

S20E13 · Terminus Part 1

Tegan and Turlough meet in the doomed corridor

Spray foam sealant is used by Kari’s raiders to plug the breach in the bulkhead they forced open, restoring airtight integrity. The hiss and flash of the foam mask gunfire sounds and masking the liner’s decay, momentarily stabilizing the environment but not erasing danger.

Before: Absent or depleted from previous use, with visible breaches allowing environmental contamination.

After: Foam has hardened, sealing part of the bulkhead, though structural integrity remains compromised.

Doctor and Nyssa recoil in the liner's horror

The spray foam sealant is deployed by Kari’s team to stabilize the breached bulkhead, rapidly expanding to plug structural gaps and buy critical time. Its hiss and acrid scent mingle with the liner’s decay, marking a small but vital countermeasure against the vessel’s collapse.

Before: Contained in handheld canisters, unused until the breach occurs

After: Partially consumed, with remnants showing along the bulkhead edges where repairs were made

Raiders seize the Doctor and Nyssa

Spray foam sealant is deployed by Kari and Olvir to plug breaches near the blast site, buying critical time to consolidate their control. Its rapid solidification halts further environmental decay temporarily, stabilizing a foothold in the deadly liner.

Before: Stored in portable canisters with Kari’s raiders.

After: Partially deployed, patches holding but showing strain under the liner’s hostile conditions.
