Product Details
- PERMANENT WATERTIGHT SEAL — ABOVE & BELOW WATERLINE — 5200 fast-cure formula in black creates a permanent, flexible bond for marine applications where a dark sealant line is preferred. Ideal for rub rails, black hull joints, windshield trim, dark deck hardware, and any visible joint where white sealant would stand out.
- 24-HOUR FAST CURE — TACK-FREE IN 2 HOURS — Skins in 1 hour, tack-free by 2 hours, reaches handling strength by 24 hours. Traditional 5200 takes up to 7 days — this fast-cure version gets your boat back on the water sooner without sacrificing bond strength.
- UV & WEATHER RESISTANT — RESISTS SALT WATER — Engineered for full sun, salt spray, and temperature extremes. The black pigment resists UV chalking and fading, maintaining a clean appearance on visible seam lines for years. Built to withstand harsh saltwater environments.
- BONDS FIBERGLASS, WOOD, GELCOAT & METAL — Adheres to virtually every material found on a boat: fiberglass, wood, aluminum, steel, gelcoat, ceramic, and most plastics. One-part adhesive sealant requires no mixing — apply directly from the cartridge.
- 10 OZ CARTRIDGE WITH GLOVES — AMERICAN OWNED — Full-size 10 oz cartridge fits any standard caulk gun. Compare to 3M 5200 Black (06504). Includes disposable gloves for clean application. Family-owned business proudly operating in the USA.

Customer Questions & Answers

Question:
What makes the 10 oz Marine Adhesive Sealant 5200 Fast Cure Black waterproof?
Answer: The 10 oz Marine Adhesive Sealant 5200 Fast Cure Black is designed to create a permanent and watertight bond, making it an excellent choice for marine environments. Its unique formulation includes a blend of high-strength polymers that cure to form a durable, flexible seal resistant to water and moisture. This characteristic is essential for applications above and below waterline, such as sealing joints in boats, trailers, and other watercraft. Users can confidently utilize it in areas exposed to harsh marine conditions, knowing it will withstand the rigors of water exposure. -
Question:
Can I use 5200 Fast Cure Sealant for underwater applications?
Answer: Yes, the 5200 Fast Cure Sealant is specifically engineered for underwater applications. Its unique formulation allows it to adhere properly and cure effectively even when applied submerged. This makes it suitable for repairing leaks in boats or sealing fittings and joints that are constantly in contact with water. Users should ensure surface cleaning and proper application techniques are followed for the best results in underwater scenarios, enhancing longevity and performance. -
Question:
Is the 5200 Fast Cure Sealant UV resistant?
Answer: Absolutely! The 5200 Fast Cure Sealant is formulated to be UV resistant, which protects the bond from degradation caused by sun exposure. This property is significant for long-term outdoor use where components may be subjected to sunlight and harsh weather conditions. Whether sealing a marine hull or fixing an outdoor application, the UV resistance ensures that the seal remains effective and isn't compromised by environmental factors, allowing for sustained performance over time. -
Question:
How quickly does the 5200 Fast Cure Sealant dry?
Answer: The 5200 Fast Cure Sealant is known for its quick curing time. It starts to set within just a couple of hours, allowing for rapid bonding compared to traditional sealants. For full curing, it generally takes about 24 hours. This quick-drying characteristic is advantageous for urgent repairs or projects that require a fast turnaround, like preparing a boat for immediate water use after repairs. Users should consider working efficiently during the initial hours to ensure accuracy in application before the seal begins to set. -
Question:
Is 5200 Fast Cure Sealant suitable for all surfaces?
Answer: Yes, the 5200 Fast Cure Sealant adheres effectively to a variety of surfaces, including fiberglass, wood, metal, and plastics. This versatility allows users to perform repairs and sealing tasks in diverse contexts such as boat construction, trailer maintenance, and home projects. However, for optimal adhesion, it's crucial to clean the surfaces thoroughly before application, ensuring that dust, grease, and moisture are minimized. This will enhance the sealant's performance across different materials. -
Question:
Can I paint over the 5200 Fast Cure Sealant?
Answer: While 5200 Fast Cure Sealant can be painted with certain types of paint after it has fully cured, it's important to note that the sealant itself is not paintable during the curing process. Users should select paints specifically designed for adherence to flexible surfaces and consider waiting until the sealant has cured completely, usually 24 hours, to avoid compromising the bond. This feature allows for aesthetic customization in projects while maintaining the integrity of the seal. -
Question:
Is the 5200 Fast Cure Sealant safe for use on drinking water systems?
Answer: The 5200 Fast Cure Sealant is not recommended for potable water applications due to its chemical composition, which may leach into drinking water. For projects involving water systems where drinking quality is a priority, users should choose a sealant explicitly labeled safe for such applications. This ensures that you achieve both the seal you need and maintain safety in drinking water scenarios, such as in boats with onboard water systems. -
Question:
What is the best way to apply the 5200 Fast Cure Sealant?
Answer: Applying the 5200 Fast Cure Sealant involves a few key steps for success. First, ensure surfaces are clean and dry, removing dust, grease, or moisture. Then, use a caulking gun for precise application, keeping a steady hand to deliver an even bead. It’s recommended to overfill joints slightly to account for shrinkage as it cures. After application, smoothen the seal with a tool for a neat finish. This method not only enhances the aesthetic but also contributes to better sealing performance against environmental elements. -

Berkland Joint Sealants Editorial Review
The BERKLAND 10 oz Marine Adhesive Sealant 5200 Fast Cure in black has received a generally positive reception from customers, particularly for its effectiveness and value. Users appreciate the product's capability to form a permanent, watertight bond above and below the waterline, making it an ideal choice for various marine applications. The sealant is formulated to be flexible, allowing for the easy removal of fastened hardware, which adds to its practicality. Although several reviews highlight the product as a cost-effective alternative to national brands, caution is advised regarding its application, especially on oily or slippery surfaces. Some customers have encountered issues when using it on certain materials, such as teak or polyethylene, and noted that storing the sealant within the recommended temperature range is crucial to ensure its effectiveness. Additionally, several customers pointed out the fine print warning labels and instructions on the packaging are hard to read, which could pose a challenge during application. Overall, the BERKLAND sealant is commended for its strong initial tack, smooth application, and ability to cover a substantial area efficiently. This product appears to be particularly appealing to those needing larger quantities of marine adhesive, especially when availability of the specific color black is limited in local stores. **
