Overview
Built for the job.
SEM® 1K Seam Sealer is a versatile, single component sealer for sealing interior or exterior seams, joints, and voids.
SEM® 29392 is a 1‑component, 10.1 fl‑oz liquid seam sealer formulated for professional automotive body repair. It is applied to seal seams and gaps before panel bonding, providing a durable, flexible barrier that integrates with subsequent coating systems.
The sealer cures to a 4 mm skin in 24 hours at 70 °F (21 °C) with a workable flash time of 5–10 minutes, allowing rapid panel alignment and cleanup. It delivers consistent coverage on a range of substrates, including aluminum, steel, OEM primer, and other primed surfaces, while remaining zero‑VOC for compliance with environmental standards.
Handling requires standard PPE: chemical‑resistant gloves, eye protection, protective clothing, and a respirator in well‑ventilated areas. The material has a flash point of 98 °C and is classified with acute toxicity, skin corrosion, and respiratory hazards; consult the SDS for detailed first‑aid and safety measures.

- Apply the sealer with a brush or roller in a single coat to the joint, working within the 5–10 minute work window at 70 °F (21 °C).
- Allow the seam to develop strength; the material reaches 4 mm thickness in 24 hours at 70 °F (21 °C).
- After full cure, proceed with sanding or finishing as required.
