What Stands Out
Fast Cure Formula
The rapid curing time of this sealant ensures projects are completed quickly, allowing for immediate use. This feature saves time for users working on urgent tasks in both above and below waterline applications.
Permanent Bonding
Designed for strong permanent adhesion, this marine adhesive creates a watertight seal that withstands harsh marine environments, protecting your investment from water damage and requiring minimal maintenance over time.
UV Resistant
This sealant's UV resistance ensures lasting performance and durability, preventing degradation from sunlight exposure. Ideal for outdoor applications, it maintains its integrity and appearance in both marine and outdoor environments.

Question:
What is 3 oz Marine Adhesive Sealant 5200 used for?
Answer: The 3 oz Marine Adhesive Sealant 5200 is designed for permanent, watertight sealing and bonding applications, especially in marine environments. It's ideal for sealing leaks, bonding fiberglass, aluminum, wood, and other surfaces that require a strong, durable hold. This sealant is suitable for above and below the waterline, making it perfect for boats, marine hardware, and even home repairs in areas exposed to moisture. -
Question:
How does the Fast Cure feature work?
Answer: The Fast Cure feature of the 5200 sealant allows it to set quickly, enabling fast bonding and sealing operations. This is particularly beneficial in marine settings where time and weather conditions are critical. The sealant achieves a robust hold within hours, which allows you to continue your project without long delays, hence saving you time and ensuring your repairs are completed efficiently. -
Question:
Is the 5200 Marine Adhesive Sealant resistant to UV rays?
Answer: Yes, the 5200 Marine Adhesive Sealant is UV resistant. This ensures that it maintains its integrity and bonding strength when exposed to sunlight and harsh weather conditions, which is crucial for outdoor applications such as boats and docks. This quality prevents cracking and degradation, ensuring that your seals last longer without needing frequent replacements. -
Question:
Can I use the 5200 Sealant on materials other than marine applications?
Answer: Absolutely! While 5200 is optimized for marine use, it can also be used in various applications beyond boats, such as in construction and home repairs. It bonds well with metals, plastics, wood, and ceramics, making it versatile for sealing outdoor furniture, windows, skylights, and more. Its permanent and watertight features make it an excellent choice for any projects that involve exposure to moisture. -
Question:
What is the drying time for the 5200 sealant?
Answer: The drying time for the 5200 Marine Adhesive Sealant varies based on environmental conditions but typically allows for handling within a few hours. Complete curing can take several days. The initial fast cure offers quick holding strength, making it convenient for urgent repairs, while the full cure ensures a durable and lasting bond ideal for high-stress environments. -
Question:
Is the 5200 Marine Adhesive Sealant paintable?
Answer: Yes, once fully cured, the 5200 Marine Adhesive Sealant can be painted over. This feature is useful for those who want to match the appearance of the seal with the surrounding surfaces. Make sure to use a compatible paint and allow the sealant to cure completely before applying any finishing coats, ensuring a seamless and aesthetically pleasing outcome. -
Question:
How do I apply the 5200 Marine Sealant?
Answer: To apply the 5200 Marine Adhesive Sealant effectively, clean and dry the surfaces that need sealing. Use an applicator gun to dispense the sealant evenly into the joint or gap. Smooth it out with a tool or your finger for a neat finish. Ensure you follow the recommended application techniques for the specific materials you're working with to achieve the best result and maximum bond strength. -
Question:
Can the 5200 Sealant be removed once applied?
Answer: While the 5200 Marine Adhesive Sealant is designed for permanent bonding, it can be removed, but it may require some effort and specific removal methods. To remove cured sealant, you'll often need to use a scraper or a sealant removal tool. Be careful to protect the surfaces underneath to avoid damage when removing the sealant, especially on delicate materials. -
Question:
What temperatures can the 5200 Sealant withstand?
Answer: The 5200 Marine Adhesive Sealant can withstand a wide range of temperatures, making it suitable for various climatic conditions. It remains effective in temperatures from freezing to hot environments, which is essential for marine applications where temperature fluctuations are common. This resilience ensures reliable performance and durability throughout the year. -

Berkland Joint Sealants Editorial Review
Berkland Marine Adhesive Sealant 5200 Fast Cure, 3 oz White offers a permanent watertight bond suitable for applications above and below the waterline, making it an exceptional choice for boatbuilding and marine repairs. Reviewers have praised its fast cure formula and strong adhesion, with many noting that it can even be applied underwater, ensuring reliable results even in challenging environments. While some users experienced difficulty squeezing the tube, the end result often proved well worth the effort, providing a waterproof seal that holds well, especially on repairs involving multiple couplers. It’s important to work in a ventilated area and to clean any excess with acetone, which can be a little messy, but ultimately contributes to the effectiveness of the sealant.
