The Most Important Component of any Marine Adhesive or Sealant: Trust.

Whether you’re boatbuilding, maintaining a fleet or repairing a single watercraft, you expect your adhesive sealants to create watertight seals. But the right ones will do much more. They will resist weathering, shock, vibration, swelling and shrinkage over time. It also means they will earn your trust. 3M designs quick-applying, long-lasting adhesives and sealants for specific conditions – below the waterline, topside and everywhere in between, on virtually any surface you can find on your boat.

The toughest sealants on the sea

Whether you’re bonding trim, toe rails, fittings or fiberglass deck components, or sealing thru-hulls, hatches, hinges, trunk joints or almost anything else on a marine vessel, 3M has an adhesive sealant that’s proven to the task. Our products have set the standard for marine excellence for more than 50 years, and they now include a new generation of advanced polyurethane and silane-modified polymers (SMPs) that further expand their range and effectiveness.

3M Marine Adhesive Sealants are specifically designed for the rigors of the marine environment, bonding or sealing everything from wood, metal and glass to gelcoat and most plastics—including fiber-reinforced plastic (FRP). Boaters have no better friend on the water.

This product, like all 3M products is outstanding. I used it to reseal a Pilothouse to deck seam that had developed some leaks. The previous seal/caulk had dried out, shrunk, and cracked. I cut it out and refilled the joint with 4000. I cleaned the area with acetone, masked off beyond the seam and applied 4000 with a caulking gun. The sealant flowed smoothly and filled the joint completely, easily resealing the leaky joint. This product is waterproof so cleanup is messy if you get it where you don’t want it. It does not smooth with a wet, gloved finger, merely smears. Apply enough to fill your joint and no more. Small overages will be “cleaned” up when you remove the masking. I applied the 4000 to a joint almost forty feet in length overall and the cure time is not so quick that I couldn’t easily pull the tape without pulling the caulk. It made an attractive seam and fixed the leak. Unlike 5200, 4000 doesn’t dry/cure so hard that it has to be ground out to remove it, but can be cut out with a knife at some future point if necessary.

I bought this to seal around the jet and drain fittings in my spa. I have a older spa (Polynesian Spa) which runs great. But the o-rings under the jet and drain fittings haven''t been made for over 15 yrs. So every few years I seal AROUND the fittings to keep the from leaking until the water heats up and the o-rings seat themselves and seal properly from the heat. Usually I use Geocel 2320 construction adhesive sealant (usually used for gutters) which is watertight and lasts a few years in the jacuz. I have also used the blue RV gasket sealant but it doesn''t last as long.
Very disappointed with the Marine 4000 in the spa. Definitely would not use this for underwater applications in warm water with chlorine. After 4 months it started turning into a white paste and began dissolving. At least it was easy to remove, tho rather gooey. But now I have to reseal the jet and drain fittings AGAIN.
I also used the Marine 4000 to seal around the kitchen faucet plate. It works very well there.

I bought this material which was recommended by the manufacturer of my RV to touch up a few seams. The material itself is probably good, but the tube that 3M packages it is worthless. The plastic nozzle came loose on the second bead application and the tube required so much pressure to dispense that it broke the seal at the bottom of the tube. The leaking of the sealant from both ends of the tube caused a huge mess, ruining my clothes and requiring me to take a bath in mineral spirits to remove it from my skin.

Ok, maybe 2 stars isn''t really fair because they don''t really market this stuff for pool repairs. Unfortunately I should have read more of the reviews because at least one other buyer mentioned having the same issue in his pool as I''m having in mine. I have a saltwater pool. This stuff is basically "melting" where it''s underwater. This fall when I winterize the pool, or maybe next spring when I go to open it - I''ll be scraping off what''s left and replacing it with something else.

It is amazing durable and professional adhesive that has amazing strength. I like to let a very little ooze out around the fitting and let it remain for a finished appearance. It seems to dry hard and shiny yet it will squeeze a little if you try with pliers. Its what I use for all above water line work, and the 3M 5200 for below water line and structural work.

If they used 3M 5200 to build roads with in Buffalo, we wouldn''t be known as the pothole capital of the country. Maybe I''ll contact 3M about this brainstorm idea ...

I have used this product on my boats for sealing under deck plates, hooks, etc... with great success. It was recommended to me for sealing horizontal seams on my RV by a local RV dealer. With my past success I thought it would be the ticket. Plus, UV is in the name, so it should be great... not so much. All of the seams I sealed last year failed. After one year in the sun, the sealant turned ashy and started coming out of every place I put it. The previous sealant I used was simply a home exterior window caulking and it lasted for ten years. Truthfully, the old home caulk was still serviceable but had attracted a lot of dirt so looked ratty.

For applications that do not see the sunlight or just occasional sunlight, this product works well and is easy to use. However, if your boat or RV sees constant sunlight, it will fail in short order.

I really like this sealant for external joints on my RV. It seems to last long, just the right amount of adhesion and it''s a nice white and doesn''t appreciably yellow (like their 4200 sealant does), although it can get dirt stuck to it (unavoidable, I think). But the last time I used this smaller tube, it was difficult to squeeze out the small bead without the benefit of a caulking gun. I bought another for small touch-up work and save money over the caulk gun size; but last time, I swore I''d never buy this size again because the squeezing effort was just too much. I haven''t opened and used this one yet. Maybe there was a problem with the first instance, but I doubt it. I expect to regret buying this size again (because of the squeezing effort), when I finally use it.

This sealant is difficult to squeeze out the tube. The first tube burst at the bottom with the pressure needed to get it out. The second tube was difficult as well, but I used less pressure. Working quite well, but some areas did not stop the water from dripping out.
