How to Install Seadek: A Step-by-Step Guide

How To Install Seadek

If you’re a boating enthusiast, you’re likely familiar with Seadek. It’s a non-skid, closed-cell EVA foam that offers a multitude of benefits, including improved traction, shock absorption, and noise reduction. Seadek is also incredibly durable and can withstand harsh marine environments. With all these benefits, it’s no wonder that Seadek is a popular choice for boat owners.

However, to enjoy all the benefits of Seadek, proper installation is crucial. In this article, we’ll guide you through the process of installing Seadek on your boat. We’ll cover everything from gathering materials to finishing the installation and maintaining Seadek for optimal performance.

Gather Materials

Cutting and shaping Seadek to fit the surface is an important step in the installation process.
Cutting and shaping Seadek to fit the surface is an important step in the installation process.

Before you begin installing Seadek, you’ll need to gather the necessary materials. Here’s what you’ll need:


Of course, you’ll need Seadek for your installation. Ensure you have enough Seadek to cover the area you want to install it on. You can order Seadek in custom sizes, so take accurate measurements of the area you want to cover.

Scissors or a Utility Knife

You’ll need scissors or a utility knife to cut the Seadek to fit your boat’s surface. A utility knife is preferable as it allows for more precise cuts.

Cleaning Supplies

Before installing Seadek, you’ll need to thoroughly clean the surface it will be applied to. Gather cleaning supplies such as a degreaser, acetone, and a clean cloth.

Measuring Tape

Accurate measurements are essential for a successful Seadek installation. Have a measuring tape on hand to measure the surface you’ll be installing Seadek on.

Heat Gun

A heat gun is necessary to apply heat to the Seadek, which will help it conform to the surface’s contours.


After applying Seadek, you’ll need to roll it to ensure proper adhesion. A roller will help you achieve this.

With all these materials on hand, you’re ready to begin the installation process.

Prepare the Surface

Before installing Seadek, the surface it will be applied to must be thoroughly cleaned and prepared. Here’s a step-by-step guide:

Step 1: Remove Any Dirt or Debris

Use a brush or vacuum to remove any dirt or debris from the surface. It’s crucial to have a clean surface to ensure proper adhesion.

Step 2: Degrease the Surface

Apply a degreaser to the surface and scrub it with a brush or clean cloth. A degreaser will help remove any oil, grease, or other contaminants that may interfere with Seadek’s adhesion.

Step 3: Clean with Acetone

After degreasing, clean the surface with acetone. Acetone will remove any remaining contaminants and ensure a clean, dry surface.

Step 4: Let the Surface Dry

Allow the surface to dry completely before installing Seadek. Any moisture or residual cleaning solution may affect Seadek’s adhesion.

Install Seadek

Now that the surface is clean and dry, it’s time to install Seadek. Here’s a step-by-step guide:

Step 1: Measure and Cut Seadek to Fit

Measure the surface you’re installing Seadek on and cut the Seadek to fit. Use scissors or a utility knife to make precise cuts. You can also use a template to ensure accurate cuts.

Step 2: Peel the Backing and Apply Seadek

Remove the backing from the Seadek and carefully apply it to the surface. Start at one end and work your way to the other, smoothing out any bubbles or wrinkles as you go.

Step 3: Use a Heat Gun to Conform Seadek to the Surface

Once Seadek is applied, use a heat gun to apply heat to the Seadek. This will help it conform to the surface’s contours and ensure proper adhesion.

Step 4: Use a Roller to Ensure Proper Adhesion

After applying heat, use a roller to ensure proper adhesion of Seadek to the surface. Roll over the Seadek in all directions to ensure a secure bond.

Step 5: Trim Excess Seadek

Finally, trim any excess Seadek with a utility knife or scissors. Be careful not to cut into the surface underneath Seadek.

With these steps, you’ll have successfully installed Seadek on your boat. Remember to take your time and follow these steps precisely to ensure a long-lasting, secure installation.

Finish the Installation

Once you’ve installed Seadek on your boat’s surface, it’s time to finish the edges and corners. Here’s how to do it:

Cutting the Edges

First, use a sharp utility knife to cut the excess Seadek from the edges of your boat’s surface. Be sure to use a straight edge as a guide for a clean, straight cut.

Sealing the Edges

To ensure a secure installation, you’ll need to seal the edges of your Seadek. You can use a marine-grade adhesive to do this. Apply a small amount of adhesive to the edge of the Seadek and use a roller to press it down. Repeat this process for all the edges.

Finishing the Corners

To finish the corners, cut the excess Seadek diagonally from the corner to create a triangular shape. Fold the Seadek over the corner and apply adhesive to ensure it stays in place. Use a roller to press the Seadek down and ensure proper adhesion.

With the edges and corners finished, your Seadek installation is complete.

Maintenance and Care

Proper care of your Seadek is essential to maintain its longevity and performance. Here are some tips for maintaining and caring for your Seadek:

Clean Regularly

Regular cleaning will help keep your Seadek looking and performing like new. Use a mild soap and water to clean your Seadek regularly.

Avoid Harsh Chemicals

Avoid using harsh chemicals such as bleach or ammonia when cleaning your Seadek. These chemicals can damage the Seadek’s surface and reduce its lifespan.

Protect from Sunlight

Exposure to sunlight can cause your Seadek to fade and lose its color. To prevent this, use a UV protectant spray on your Seadek regularly.

Store Properly

When not in use, store your Seadek in a cool, dry place. Avoid storing it in direct sunlight or in areas with high humidity.

By following these maintenance and care tips, you can ensure your Seadek lasts for years to come and continues to provide you with the benefits you love.
