How to Fill Gaps in Wood Deck

However, one of the issues that come with having a wood deck is the inevitable gaps between each piece of lumber. These gaps can lead to water damage, accelerated decay, and deterioration; which is why it’s wise to take measures into filling these gaps as soon as you notice them.

In this blog post we will discuss how to fill gaps in wood deck quickly and safely using simple tools and products, so your wood deck can look brand new all year round!

What Causes Gaps in Wood Deck?

1. Incorrectly Installed Boards

One of the most common causes of gaps in a wood deck is the boards not being installed properly. Improper installation of decking boards can lead to spaces between them, which can then let in water and debris that will eventually damage the overall structure.

2. Shrinkage & Expansion

Shifting temperatures throughout the year can cause wood to expand and contract, resulting in gaps between the boards. This is a common issue with wood decking, but it can be easily fixed.

3. Poor Quality Deck Boards

Low-quality deck boards that are not made from treated lumber or pressure-treated wood will quickly become warped and rotten over time due to exposure to moisture and sunlight. Gaps may also form if the boards are not properly sealed.

How to Fill Gaps in Wood Deck in 6 Easy Steps

Step 1: Sand Down the Boards

The first step to filling gaps in your wood deck is to sand down the boards. Use an electric sander or a sanding block to gently smooth out any irregularities between the boards and fill in any cracks. Also, make sure the gap is free of any debris before applying a filler.

Step 2: Apply Wood Filler or Putty

Once the boards are sanded down, you can apply wood filler or putty to fill in any gaps between them. Make sure to follow the manufacturer’s instructions for how to best apply it and what type of surface it should be used on.

Step 3: Allow the Filler to Dry

Once the filler is applied, it is important to allow it to dry completely before moving on to the next step. This may take several hours or overnight depending on what type of filler was used.

Step 4: Sand Down the Filled Area

After allowing the filler enough time to dry, use a sanding block or electric sander to smooth down the filled area. This will help ensure that it is completely even with the rest of the wood surface. You have to be careful not to sand too much, though, as this can cause the filler to become uneven and visible.

Step 5: Stain or Seal the Filled Area

Once the filled area is smooth and even with the rest of the wood surface, you can then stain or seal it. This will help protect it from water damage and other elements that may cause further deterioration over time.

Step 6: Apply a Finishing Coat

The final step is to apply a finishing coat. This can be either a varnish or polyurethane, depending on what type of look you are going for. Make sure to follow the manufacturer’s instructions for how to best apply it and how many coats should be used.

By following these six easy steps, you can easily fill gaps in your wood deck and ensure that it will last for years to come. No matter the cause of the gap, these simple steps can help you get rid of them quickly and safely.

Apply a Finishing Coat

As always, if you are having trouble with any step or aren’t sure what type of product to use, consulting a professional is always an option. With a bit of knowledge and the right supplies, you can easily fill gaps in your wood deck and restore its beauty. So get to it! The sooner you take care of it, the better off your deck will be in the long run.

Some Extra Tips to Fill Gaps in Wood Deck

1. Do Not Overfill the Gaps

When filling the gaps, it is best to try to fill them as much as possible without overfilling. This will help keep your deck looking both aesthetically pleasing and structurally sound. Also make sure that the material you choose to fill the gap is made of a durable material that can stand up against the elements.

2. Take Your Time and Clean Up Properly

When filling gaps in wood decks, it is important to take your time and make sure everything is done correctly. This will help ensure that the gap filler does not come off or become loose over time. Once you have filled the gaps, make sure to clean up any excess material around the edges of the gap so that it looks neat and professional.

3. Choose a Product That Matches Your Decking Material

When filling gaps in wood decks, it is important to use a product that matches your decking material. This will ensure that the color and texture of the gap filler will blend in nicely with the existing decking material. If you are unsure of what product to use, it is best to consult a professional who has experience in this field.

4. Use a High Quality Gap Filler

To ensure that your gap filler lasts for many years, make sure to use a high-quality product when filling gaps in wood decks. Choose a product that is designed for outdoor use and can withstand the elements without cracking or peeling. It is also important to make sure the gap filler is compatible with your decking material, so check the manufacturer’s instructions before purchasing any gap filler products.

5. Finish With a Protective Coat

Once you have filled the gaps in your wood deck, it is important to finish the job with a protective coat. This will help protect the gap filler from fading and discoloration over time, as well as helping to seal it in place. Depending on your decking material, you may want to use a clear sealant or water-based polyurethane to give your deck protection against moisture and dirt. It is best to consult a professional before applying any kind of protective coating.

Finish the Job With a Protective Coat

Following these tips will help you fill gaps in wood decks with ease and get the job done right! With the right materials and careful attention to detail, your deck will look as good as new for years to come. Good luck and happy decking!
