3M Marine Sealant, White, 10 oz

A tough seal that stays flexible when the boat keeps working.

Made for solid holding above and below the water line.

Product Overview:

Marine sealant is one of those jobs where you want the bead to sit right, then settle in and hold its nerve. This one does that. The 3M 10 oz white polyurethane adhesive sealant gives you a clean, workable finish and a strong bond that keeps its shape. It stays flexible, so movement from shock, vibration, swelling, or shrinking does not throw it off. Picture a repair that looks neat, feels firm, and does not fuss when the water gets involved. That is the kind of calm you want on deck or below.

Key Features:

• Strong polyurethane bond delivers a steady seal that holds above or below the water line, plain and simple.
• Flexible finish gives with movement, so hull stress, vibration, and swelling do not crack the seal.
• Easy application works well with a manual caulking gun, then stays workable with a trowel or spatula for up to 4 hours.
• No sag or flow helps the bead stay put in vertical or horizontal seams, which saves a lot of fiddling.
• Weather and salt water resistance keeps the seal steady in rough conditions, so you are not back at it too soon.
• Fast cure timing turns tack free in 48 hours and fully cures in 5 to 7 days, so you can plan the work without guesswork.
