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 29382 is a 1‑component, 10.1 fl‑oz seam sealer formulated for high‑quality automotive panel sealing. It is supplied in a beige liquid tube and cures to a flexible, durable seal, making it ideal for filling seams and joints on repaired panels before final finishing.
The sealer provides a work time of 5–10 minutes at 70 °F (21 °C) and achieves full cure of a 4 mm depth in 24 hours under the same conditions. Zero‑VOC formulation ensures compliance with environmental regulations while delivering professional‑grade coverage on compatible substrates such as aluminum, steel, OEM panels, and primed surfaces.
Handling requires standard PPE: eye protection, chemical‑resistant gloves, protective clothing, and a respirator. Use in a well‑ventilated area; the product has a flash point of 98 °C and is classified with acute toxicity, skin corrosion, eye damage, and other hazards per the SDS.

How to Use
For use on properly prepped primed or painted surfaces and bare metal
- Clean and dry the substrate (aluminum, OEM primer, steel) to remove dust, oil, and loose material.
- Stir the 1‑component seam sealer thoroughly; no mixing ratio is required.
- Apply the seam sealer with a brush or roller, working within the 5–10 minute work window at 70 °F (21 °C).
- Allow the first coat to cure for 24 hours at 70 °F (21 °C) to achieve a 4 mm film thickness.
- If additional thickness is required, apply a second coat after the first coat has cured, then repeat the 24‑hour cure.
