Read on to know a detailed overview of this adhesive from the rest of this review.
Marine adhesives are frequently criticized because of the inability to form a strong and flexible bond as they have to deal with salt water and various weather conditions. For this reason, most of the adhesive gets booed by the users. 3M Marine Adhesive Sealant 5200 seems different in this regard. Let’s find out how much of that assumption is true.
Whom is this product ideal for?
This adhesive is a multitasking product. One can prevent leaks and water damage of a bathtub or a shower. If a current of cool breeze penetrates through the door or windows, you can easily prevent that by caulking it around the holes. This is suitable for the kayak fishers too as they need to deal with joints of boat hardware in a wet condition. But make sure that the label of the products allows you to buy one. Because, most of the 3M products label its industrial/commercial products only to be used by professional, commercial and industrial customers. It comes in three different sizes such as 1 fl oz, 3fl oz, 10 fl oz, and 640 fl oz. One can choose the right sized one as per his/her need.

Common Questions and Answers
- Question : How long it does last after opening the tube? Answer :
It has a shelf time for almost 24 months if unopened but doesn’t remain effective after a few days if opened.
- Question : Can the excess adhesive be removed after the joints being cured? Answer :
It’s not easily removable. You have to cut or sand the excess part once it gets cured.
It’s not wise to believe in the fabricated advertisement of the seller or manufacturer. The best reviews come from experienced users. I have bought one tube of this marine adhesive to know how well it works.
I have applied the thin paste to a hole in my kayak and tried to fix some loose joints. I’ve found this thing very useful. The only downright awesome thing it has is that it takes too much time to cure. You have to keep patience to get a full-fledged strong bond and sealant. But you’ll never think of another adhesive after watching the outcome. It can form a very strong weather-resistant seal that allows the joints to be flexible when needed. This flexibility helps the boat or any joint fight stress, shock, shrinking and vibration. One may complain about the curing time initially, but he/she will love the permanent sturdy seals once it gets cured.
2. Ease of use
The tube has great usability as it comes with a nice nozzle. So, I could use it easily on the right spot. I used the nozzle to apply the adhesive effectively to the parts I wanted to bond. I faced no problem except the thinness of the adhesive. This caused it to run down and drip to the places where no sealant is needed.
How to use and store White 3M Marine 5200 Adhesive / Sealant?
The efficacy of an adhesive depends on the application process. And it won't produce optimum output if you can’t store it correctly.
1. Where to use?
Before applying the adhesive, abrade the surfaces with quality abrasive. Get rid of the residue to get enhanced bond strength. Cut the nozzle tip carefully to match the desired size of the bead. It’s better to place the cartridge into a caulk gun. Using the gun will help you get more control over the application procedure. Then, apply the adhesive to the desired parts. Remove the excess material after applying the adhesive. Use a dry cloth and adhesive cleaner to clean the residue. Keep an eye on your hand. Make sure that no glue sticks to the hands.
2. How to store 3M Marine 5200 Adhesive?
This product remains best usable if kept at 60-80℉ which is 16-27 ℃. If you keep it within this range of temperature it will achieve maximum storage life. Higher temperature reduces the average storage life and lower temperature increases the density of the glue. You can keep this product for two years without any nuisance if unopened. Experts suggest using the whole tube as early as possible after opening the lid. Keep the tubes well protected from outer atmospheric air and particles to get prolonged usability.
It has a great rating on Amazon, and more than 600 reviews prove that it has already earned a place in the heart of the users. The overall rating is 4.4/5. Most of them are happy with the performance of this adhesive both in dry and wet condition. The complaints are mostly about the long curing time. Some joints took up to seven days to cure completely. But, once it gets cured, everyone is content with the strong, watertight bonds it creates.
Our Final Thoughts
3M 5200 Sealant has polyurethane polymer as a constituent. This chemical reacts with the moisture to create watertight, strong and flexible bonds. It can deliver non-shrinking and permanent adhesion to the gel coat, fiberglass, and wood. It has great resistance to water and salt. The flexibility helps this adhesive to create a reliable and durable bond fighting the vibrations, shock or other structural movements of the boat. If you can consider the long curing time as a minor issue, I will recommend using 3M Marine Adhesive Sealant 5200 White without a second thought.
