DIY SeaDek Installation: A Step-by-Step Guide for Boaters

SeaDek boat flooring is designed for boat owners who want to take matters into their own hands. So while it sounds intimidating, it’s perfect for beginners.

However, it doesn’t mean it’s as simple as navigating calm waters on a sunny day with a tailwind.

If you’re here because you don’t know where to start, we’ll show you the ropes. Read on to learn more about SeaDek installation and our pro tips.

What is SeaDek? 

SeaDek is a brand of high-quality marine flooring and decking material. This durable, non-skid surface can significantly enhance your boating experience, comfort, safety, and aesthetics.

SeaDek is highly customizable, offering boat owners colors, patterns, and textures to choose from. This enables you to pick the one that matches your desired comfort level and vessel’s design.

Since SeaDek isn’t limited to marine flooring, you can get creative with this material. You can apply it on different boat surfaces as well, including cooler tops and swim platforms. Keep this in mind when DIYing the installation process.

That said, maybe you’re asking yourself: Is SeaDek hard to install? It isn’t–if you know the right steps to take. In the next few sections, we’ll show you how you can do it on your own.

Step-By-Step: How To Install SeaDek Boat Flooring Without A Professional

The following steps will help you install SeaDek on your boat neatly and professionally:

1. Determine The Deck Areas And Their Measurements 

Your DIY boat flooring project begins with deciding what areas you want covered with SeaDek sheet material. Once you have a clear idea, you can proceed to get measurements for each part of the project. 

2. Get a Quote from a Reputable Provider

SeaDek pricing varies based on how many sheets you need to complete the project. The more accurate the measurement, the likelier the budget will stay on track. Take images and label them properly before sharing them with a reputable provider, like Decked Out Factory.

Pro Tip: Allowing for a bit of excess is a good idea so you don’t fall short if something goes wrong. Plus, you can use the remaining sheets to spruce up boat accessories, such as swim platforms.

3. Prepare The Materials Needed 

Keep all your materials and tools within reach by completing them before you begin the installation process. Here are some basic examples:    

  • SeaDek kit (pre-cut or custom-fit)
  • Pencil or marker
  • Straightedge or ruler
  • Masking tape 
  • Isopropyl alcohol or acetone
  • Lint-free rags 
  • Utility or razor knife 

The next steps will outline how to install your SeaDek flooring.

4. Prepare The Surface

How do you prepare a surface for SeaDek? Simple. Wipe it with acetone or isopropyl alcohol using a clean, lint-free cloth.

This is a good way to ensure it’s free from any dirt, wax, or residue. Wait until it dries completely before proceeding to the next step.

5. Fit The SeaDek and Make Adjustments

Before installing the piece, check if the SeaDek pieces fit correctly and align with the contours of the surface. Don’t remove the adhesive backing just yet. For proper alignment of the SeaDek pieces, measure and mark the boat's centerline with a pencil or marker.

Also, mark the areas that need adjustment. To trim them to the correct size, use a straightedge, ruler, utility knife, or razor blade. This step requires precision, so don't rush it.

6. Apply The SeaDek Pieces

The next step involves learning how to cut and install Seadek flooring. Take the corner of the SeaDek piece and peel off a small section of the adhesive backing. Press it down onto the surface, aligning it with the marked centerline.

Slowly peel off the rest and apply ample pressure to stick it to the surface. Repeat the process for each SeaDek piece, taking one section at a time.

After every piece, smooth out air bubbles and wrinkles using a clean, lint-free rag. Push the trapped air from the center outward. Pro Tip: If there are stubborn ones, a heat gun may be necessary. You only need the low setting to make the pieces more pliable and easy to apply.

7. Give Your Deck Flooring Time To Cure

Following installation, allow SeaDek to cure for the recommended amount of time. Keep the SeaDek away from water or extreme conditions during this time.

Note: Each kit may have variations. Refer to the installation instructions provided by SeaDek for your particular kit.

So, there you have it. You now have professional-looking marine flooring for your vessel. Great job, you’re set to sail.
