## Description

3M Marine Adhesive Sealant 5200 is a tough, flexible polyurethane for permanent bonding and sealing your RV, boat or other watercraft. It is ideal for use on wood, gelcoat, fiberglass, metal and more. It is recommended for interiors, below the waterline and any other places that are shielded from sunlight. It applies right from the container – no mixing is required. It becomes tack-free in 48 hours, and cures to form a firm, flexible, waterproof seal on joints and boat hardware. Far more than a marine caulk, tough, flexible Marine Adhesive 5200 dissipates stress caused by vibration and shock, and won’t crack under dynamic force. It resists saltwater, wind, weather and temperature extremes for long periods of worry-free enjoyment on the water. In fact, for more than 50 years, 3M Marine Adhesive Sealant 5200 has been used and trusted as a marine sealant by professionals in some of the most demanding conditions on earth. Polyurethane sealants provide strong, flexible durable elastomeric bonds that seal against the elements. These sealants excel in challenging industrial, transportation and construction applications. Polyurethane sealants are available in a wide variety of Shore A hardness, open time and colors to meet many application needs. Choose a 3M Manual or Pneumatic Applicator for dispensing 3M adhesives sealant cartridges and 400ml/600ml sausage packs.

Review: Permanent means permanent! - This is an excellent adhesive, which will basically stick anything to anything. It is totally waterproof. I've used it on everything from sticking rubber thresholds to concrete to re-gluing shoe soles with excellent results. Just be aware that it will NEVER release it's bond and you will destroy whatever is stuck together trying to separate it. If you want a permanent and impervious bond from now until the end of time, this is the stuff.
Review: TAKES 7 DAYS TO CURE - TAKES 7 DAYS TO CURE Needed to reseal my 12v 100ah lifepo4 battery. My battery design is pretty dumb and they put the handle on the top lid which was only sealed with the bare minimum of a few dabs of some type of similar adhesive on the side that came undone. The only downside to ordering it online was that the nozzle was cracked at the bottom and broken off of the retainer ring but the nozzle was still usable. Ive used the 3m 5200 adhesive sealant before so I already knew what to expect. If you can use caulk gun you can use this..but make sure you dont get it on you or its really hard to get off. Gas will work but it sucks lol. i do wish I had gotten the 3m 5200FC that cures in 24 hours instead though.

### ⭐⭐⭐⭐⭐ Absolutely amazing product
*by C***S on April 4, 2026*

Purchased this product to attempt to seal a challenging flashing issue which has three different material in an awkward transition. I removed all the material from the previous two attempts to waterproof the area, leaving a larger than previous opening to work this material into. After cleaning and prepping the surfaces, I began to applying this 3M product. It is thick, but not problematic to dispense - possibly other reviewers were dispensing through a smaller orifice than me - I used the full tube opening without a tip. The product is exceptionally easy to manipulate and smooth out - almost putty like. Unlike other products like silicone and polyurethane, it didn't stick much to my applicator and thus stayed were I wanted it (without sag) and also smoothed out easily. Bottom line is it adhered to all three materials, filled the voids perfectly, looks great, and the leak is no more! I highly, highly recommend this product - it's amazing!
