5200 Marine Adhesive Sealant

3M 5200 is a single part sealant that cures to form a firm, rubbery waterproof seal. When fully cured, this high strength marine adhesive remains flexible and suitable for use where shock, vibration, shrinking or swelling are concerns.

Use 5200 on wood, fiberglass, hardware, motors, on fiberglass transoms, seams, joints, between struts, and planking stern joints. This permanent adhesive bonds and seals: fiberglass deck to hull, wood to fiberglass, portholes and deck fittings, motors on fiberglass transoms, under moldings, hull seams above and below water line, centerboard trunk joints, between struts and planking, stern joints and more.

Apply with a manual caulking gun. Sealant remains workable with a trowel or spatula for up to four hours, and won't sag or flow in vertical or horizontal seams.

This high performance polyurethane adhesive sealant becomes tack-free in 24-48 hours, and completely cures in 5-7 days with no shrinking. The seal is extremely strong, retaining its strength above or below the waterline. 5200 stays flexible and allows for structural movement.

Consider using 5200 Fast Cure instead if the quickest possible cure rate is a consideration. It has slightly less tensile strength, but provides full cure in as little as 24 hours.

Applied with a 1/4" bead then spread with a putty knife, this stuff didn't turn out to be nearly as messy as other reviews led me to believe. Maybe it's worse on fiberglass or a protected wood, but I applied to raw pine and it worked like a charm.

If you are using 3M 5200 above the waterline with almost any material, and below the waterline with a metal that won't naturally introduce even a small amount of corrosion, then you've got a good product.

The problem is less with the adhesive itself than the materials glued and then kept submerged in seawater. Copper, for example, when under stress, won't stay stuck to the wood to which it has been glued. It seems that the copper slightly oxidizes, releasing the glue from the metal. 3M 5200 liberally applied did not appear to prevent this from happening.

I think the product is good, and I use it a lot, but for certain applications (as with most things) it won't work.

    Used this to seal a leak in my classic Chris Craft. Worked wonderfully, if messy. Be sure to have rags and some gasoline for clean up. And wear gloves! Also let it dry for at least 48 hrs. But works wonderfully.

      I was using this product to seal the deck to hull joint. It would not stay in place and ran down the hull. It took 4 days to cure. After it cured it did provide a water proof bond.

          Comments about 3M 5200 Marine Adhesive Sealant:

          Put a new sonar on the boat and needed to drill out the hole in the transom a bit more. Used the 5200, weather was colder, closer to mid 40's to low 50's and it came out pretty solid, just had to babysit it for a bit as gravity factored in and it did settle a bit, realized that after the application.

          Once it cured a little bit the wires held all in place. Optimal conidtions are 70 degrees F and 50% humidity. Again, I was closer to mid 40's so I wet paper towels and put that over the caulk, over the last 2 days of curing. Cured in 7 days with no issues.

          The boat is garage kept, but in an unheated garage, this stuff works extremely well and held up to a full day of fishing in 38 degrees, exactly 7 days after applying.

                Comments about 3M 5200 Marine Adhesive Sealant:

                5200 is strong, slow setting adhesive caulk. Any time I am drilling holes for screws or bolts I coat all the threads and inside the hole to prevent any water intrusion. You can use it anywhere you need a strong bond. Dry time is 7 days for a full cure, you have plenty of time to work with it, make sure you clean up well when you are finished. This does expand as it dries so I usually go back after a few hours and remove more excess when looks are important. You can speed the dry time by misting with water.
