5 Spongy Boat Floor Repair Tips: What You Need to Know

First, you should know what a spongy boat floor is. If you see the deck being spongy, you can also find a place where the boat is soft. In fact, many a time, you may find the entire deck being spongy and soft. In that case, you have to replace the entire deck. But if you find a soft spot, you can repair it and get tight and strong boat flooring again. 

Note that the spongy flooring is made because of the middle part between the fiberglass layers. It can be wooden or other material that goes in between the two fiberglass sheets. Between the sheets, there remains a layer that gets damaged or rotted. This is the reason why the boat flooring becomes bouncy. So you need to repair the soft spot only where the damage has been identified. 

Now let’s come to the tips of repairing a spongy boat floor. Below are some tips that can make the repairing more efficient and fast: 

Tip 1: Support The Deck

It is important that you support the deck first before starting the project. As the deck is already spongy, the inner layer is quite fragile. So if you don’t add support, the deck can break or crack. 

Also, without support, it is hard to work for the entire deck. When the deck is stable, you uniformly spread the epoxy or putty on the flooring. The structure needs to be firm and stable to work on it properly. With a frame or support, you can fix the soft spot as well as look into the other parts of the deck closely. 

Tip 2: Wear Safety Gear

You should wear safety gear before working on this project. You need to work with different types of chemicals like epoxy, glue, etc. These things release toxic fumes as well as are harmful to your skin. This is why you need protective gear to protect yourself. 

You should wear gloves and a face mask before you work on this project. Besides that, wear goggles to safeguard your eyes. Do this task in a ventilated space so that you don’t breathe in the fumes. 

Tip 3: Make A List And Get Necessary Things

Don’t start repairing the spongy boat floor out of the blue. You should first get all the tools and materials, plan the project and then start with it. Also, collect the items long before you plan the project so that you can get the items if you miss out on anything. 

Items like the painting brush, filler, suitable epoxy, wood or materials, gel coating, etc. should be bought before you start the project. So make a list of what you would need, buy them, and recheck whether you need anything or not. 

Tip 4: Plan The Task And Be Cautious

Planning the project is very important to do the task efficiently. Create a time frame and then work on the boat deck. Before that, you should check the soft spot and see the areas you need to repair. On top of that, decide which material to use first and which one the next. 

But what caution is needed? The caution is that you should not mix the epoxy and other materials before you start the project. These things harden very fast. This is why planning is needed. Mixing and applying should be accurately done for the best result. Thus you have to plan and prepare cautiously. 

Tip 5: Cut The Deck And Inspect First

Before you start the project, you should inspect the area first. For that, cut the soft area a bit and then you can understand how to repair it. If the problem is minor, you can use a filler to repair the damage. On the contrary, if the problem is major, you would need to cut open the deck and then repair the soft area. 

For instance, fiberglass delamination can be repaired easily without doing much hard work. Applying epoxy and replacing the damaged layer can help you get a new layer of fiberglass. So make holes to inspect the area first and then plan your project. 

4 Steps To Repair Spongy Boat Floor: Know The Best Way

Now that you have the best tips in your hand, you have to learn the right procedure. Repairing a spongy boat floor is not so difficult if you follow a certain path. From my knowledge, I have made a short step-by-step guide so that you know the basic mechanism. 

So let me tell you the easy steps to repair a spongy boat floor: 

Step 1: Identify and Cut Open The Soft Spot

The first task is to identify the soft spot that has to be repaired. You can knock on the surfaces and a hollow sound would show that the area needs repairing. Mark this hollow area. Similarly, you may find several spots that are affected. Mark these areas too. 

Now, drill a hole in one of these spots so that the tip of a saw can enter the hole. Slowly, insert the saw and cut open the affected areas. 

Step 2: Wax And Dewax The Area

Pour a dewaxing solution into the holes you have drilled. Pour enough so that it pops out of the hole. Now grind through the hole to make a slope inside. There is a small calculation. For one inch of deck thickness, the slope would be 12 inches.  

Then you have to wax the hole. To do that, take the flooring material, cut it slightly bigger than the hole you have drilled. Now spray a paste wax like polyvinyl alcohol on one side and paste this side towards the hole using duct tape. 

Step 3: Fill The Holes

Now is the turn to fill the holes with the fiberglass cloth. Cut the fiberglass clothing you need. Ideally, for one inch of boat flooring thickness, 1/32 inch of fiberglass cloth is needed. Cut ½ inch of fiberglass mat for each hole and you would need two layers of fiberglass cloth to cover up the soft areas. 

Step 4: Put The Finishing Layer

Now that the holes are filled, you have to work on the entire deck. For that, use a mixture of gel coat resin and apply this with a brush on the areas you have applied wax previously. Now let the gel coat dry out on these surfaces. 

Next, mix the hardener and epoxy resin and start applying three layers of the solution on the fiberglass before it starts to harden. With a roller, press the fiberglass gently on the epoxy. Wait for 24 hours to let the fiberglass sheet settle on the flooring. 

Note that if the damage is minor, you can simply fill the hole with putty to cover the damaged or rotted area. Also, in case the entire middle area is damaged, you must replace the entire layer beneath the fiberglass rather than repairing the boat deck. 

Frequently Asked Questions: 

Can You Fix Soft Spots On A Boat? 

You can easily fix soft spots on a boat. Soft spots are nothing but a rotted or damaged area just beneath the upper layer of the boat flooring. If the damage is minor, you can surely fix it easily. 

To fix the soft spots or the spongy boat floor, you have to make a hole through this spot. Check for a hollow sound and drill a hole. Now use a resin-based filling agent to fill this hole.

This solution should go inside and fill the gaps and holes that have been made due to the damage. Let the filler settle into the hole and then you can install the fiberglass countertop on the hole. That is the easiest way to fix the soft spots on a boat. 

How Do You Fix A Soft Spot On A Fiberglass Boat? 

Note that you can fix a fiberglass boat soft spot in many ways. You need not always make holes or fill up the affected areas. There are other ways of repairing the damage too. 

Many a time, sanding the affected area gives a good result. If the area is rotted, you can sand away the rotted portion of the flooring. With the hand sander, sand away the area that is affected beneath the layer of fiberglass.

Keep sanding until all the damaged layer goes away. It may even reach the layer of fiberglass beneath the soft spot. In that case, sand the fiberglass too to remove the entire rotted area. Next, install a new layer of fiberglass and plywood to repair this area. 

Can You Repair Fiberglass With Epoxy? 

Not only the soft spots are dangerous but sometimes, the fiberglass layer can get damaged too. What to do in that case? Most people would use epoxy resin to fix the issues on the fiberglass layer. 

Yes, you can repair fiberglass with epoxy. In fact, it is the most reliable agent to repair fiberglass flooring. This is because epoxy bonds very well with fiberglass. But note that it alone can’t do the best work.

For the best result, you should mix polyester with epoxy. An epoxy resin adheres firmly to the fiberglass flooring. In fact, polyester gel coating is also a good alternative to epoxy. 

How To Fix Fiberglass Delamination? 

Fiberglass delamination is a common problem when you roughly use the boat deck. However, the distressed fiberglass layer can be fixed if you know the right procedure. 

To fix delaminated fiberglass, you need to follow similar steps you use for fixing soft spots. You have to make a number of deep holes through the deck. Now pour epoxy resin through these holes and let it dry very well. This can fix the issues fairly. Then you can have a new layer of fiberglass clothing on these holes to merge with the entire deck. 

Final Thoughts: 

I have covered pretty much everything you needed to know about fixing a spongy boat deck. Starting from the tips to the steps of repairing, all have been mentioned in this article. 

Now it is your turn to gather the tools, find out the spongy areas, and fix them! Go and make your firm boat deck!
