This durable sealant from EMSEAL forms a strong, waterproof barrier that insulates against moisture, cold, and noise. Its UV-stable formula makes it well-suited for indoor and outdoor applications where protection from the elements is needed. Simply apply it to any metal surface, from pipes and vents to siding and roofing, that will not crack or shrink over time. Help shield your home or workplace from drafts and temperature extremes. The thick, pliable texture spreads easily and bonds tenaciously for long-lasting weatherproofing performance. Suitable for all climates, this multi-purpose sealant reliably blocks moisture and sound penetration wherever added insulation is desired. Expands to fill joints and gaps.
