How Do You Seal a Kayak Hatch?

Kayaking is an exciting outdoor activity that many people love to engage in. Whether it’s for leisure or exploring new waters, kayaking provides a great experience.

Having a kayak hatch is essential as it provides storage space for your gear, food, and other important items. However, to ensure the safety of your items, you need to seal the kayak hatch properly. In this article, we will discuss how to seal a kayak hatch effectively.

Step 1: Clean the Hatch

Before sealing the kayak hatch, it’s crucial to clean it thoroughly. Use a clean cloth and warm soapy water to wipe down the area around the hatch and inside the hatch itself. Make sure there is no debris or dirt left behind.

Step 2: Dry the Hatch

After cleaning the hatch, dry it off with a clean cloth or towel. Ensure that there is no moisture left behind before proceeding with sealing.

Step 3: Apply Sealant Tape

The next step is applying sealant tape around the perimeter of your kayak hatch. Sealant tape is an easy-to-use solution that creates a waterproof barrier between your gear and any water that may enter through gaps in your kayak’s hatch. Start by removing any backing paper from one side of the tape and then carefully apply it along the edge of your kayak’s hatch opening.


  • It’s essential to use high-quality sealant tape when sealing your kayak’s hatch.
  • Be careful not to stretch or pull on the tape too much as this can cause air pockets or gaps in its coverage.
  • Make sure that you cover all edges evenly for maximum protection.

Step 4: Apply Marine Silicone

Once you have applied sealant tape to the kayak hatch, it’s time to apply marine silicone. Marine silicone is an effective adhesive that creates a strong and durable seal. Apply a small amount of marine silicone along the edges of the sealant tape and smooth it out evenly using your finger or a small brush.


  • Use gloves when handling marine silicone to avoid skin irritation.
  • Ensure that you apply an even layer of marine silicone to prevent any gaps or leaks.

Step 5: Let it Dry

After applying the marine silicone, let it dry completely before using your kayak. It’s recommended to let it dry for at least 24 hours before exposing it to water.


  • Avoid touching the sealant tape or marine silicone while it’s drying as this can cause smudging or affect its effectiveness.
  • Store your kayak in a dry and cool place while waiting for the sealant to dry.

In Conclusion

Sealing a kayak hatch is essential for keeping your gear safe and secure while kayaking. By following these simple steps, you can ensure that your kayak hatch is properly sealed and protected from water damage.

Remember to use high-quality sealant tape and marine silicone, clean and dry the hatch thoroughly, and let the sealant dry completely before using your kayak again. Happy kayaking!
