Choose this seam sealer for high-quality sealing of seams and joints on primed metal or painted surfaces, and even on bare metal. It applies easily and is formulated for long-lasting support to the seam without shrinking, cracking, or causing unpleasant odors.

    Fill in Gaps with Confidence
    With its thick consistency, our 3M™ Urethane Seam Sealer is an excellent gap sealer and you can feel confident using this sealer to fill large voids between parts where they occur. Designed to be used over epoxy or urethane based primers, the sealer comes in several colors to enable color matching. Note that the sealer should be top coated when exposed to ultra violet rays.

    Excellent Performance in High Heat and Humidity
    While some seam sealers require cure time in a completely dry environment, our 3M™ Urethane Seam Sealer is moisture-curing so it provides a reliable seal regardless of moisture or humidity in the air. It can be painted after 30-45 minutes.
