Whether you’re aiming for a natural, blended finish or a more noticeable repair, choosing the right filling material is crucial. Fortunately, there are numerous options available, each with its own strengths and limitations. From traditional wood fillers to epoxy-based solutions, the choice ultimately depends on the size of the gaps, your desired finish, and the type of wood you’re working with. This comprehensive guide will walk you through the best practices and techniques for filling gaps in your wooden floors, turning those blemishes into a thing of the past, revealing the inherent beauty of your flooring once more.
Understanding Gaps in Wooden Floors
Gaps in wooden floors are a common occurrence, especially in older homes, but also in newly installed floors. These gaps can be caused by several factors, including:
- Changes in humidity: Wood is a hygroscopic material, meaning it expands and contracts with changes in humidity levels. This can lead to gaps forming between the boards during dry seasons.
- Natural movement of the wood: Over time, wood can naturally shrink and move, especially if it is not properly acclimated to the environment. This movement can cause gaps to widen or even appear where none existed before.
- Improper installation: If the wood flooring was not properly installed, gaps can form between the boards due to inadequate spacing or poorly secured boards.
- Foundation issues: In some cases, settling or movement within the foundation of your home can also contribute to gap formation in wooden floors.
It’s important to note that minor gaps in wooden floors are usually a normal occurrence. However, larger gaps can not only affect the look of your floor but also cause drafts and even instability. Therefore, it’s essential to address these gaps promptly to restore the structural integrity of your floor and enhance its aesthetic appeal.
Finding the Right Solution for Filling Gaps in Your Wooden Floors
When it comes to filling gaps in wooden floors, there are several options available, each with its own unique properties and benefits. The best solution will depend on a few factors like:
- The size of the gap: For smaller gaps, wood filler or wood putty might be sufficient. However, larger gaps may require a more durable solution like shims or epoxy.
- The type of wood: Hardwoods like oak or maple are typically harder to fill than softer woods like pine. You’ll need a filler that binds well to the wood and doesn’t shrink after application.
- The desired finish: If you want a natural finish, a wood filler that matches the color of your floor would be ideal. For a more noticeable repair, you may choose a contrasting color filler.
To help you choose the best filler for your unique situation, here’s an overview of the most popular options available:
Traditional Wood Filler: A Classic Choice
Traditional wood filler is a popular choice for filling gaps in wooden floors. It’s made from a mixture of sawdust, wood glue, and other additives, and comes in a variety of colors to match most wood types. This filler is easy to apply and sand, making it a good option for DIY projects. However, traditional wood filler can be prone to cracking and shrinking over time, especially when used to fill larger gaps.

Wood Putty: Ideal for Small Gaps
Wood putty is similar to wood filler but often contains more glue, making it a bit thicker and more durable. Wood putty is excellent for filling small gaps and cracks in wooden floors. Although it does not shrink as much as traditional wood filler, wood putty is not as durable for larger gaps, and can also be susceptible to cracking and shrinking over time.
Shims: Ideal for Subfloor Gaps
Shims are small, thin pieces of wood that are used to fill gaps between the subfloor and the finished flooring. They are particularly useful for filling large gaps or uneven subfloors, by providing a smooth surface for the finished flooring to rest upon. Shims can be made from different materials like pine, oak, or even plywood, and are available pre-cut or require cutting to fit the specific gap.
Epoxy-Based fillers: Durable for Large Gaps
Epoxy-based fillers are a durable and long-lasting option for filling large gaps in wooden floors. This type of filler has excellent adhesive properties and is very strong, but applying it is a bit more complex and requires specialized tools. Epoxy-based fillers are also resistant to water and moisture, making them a good choice for bathrooms and kitchens.
Essential Tips for Filling Gaps in Wooden Floors
Now that you’ve chosen the right filler for your project, here are some expert tips to ensure a successful repair:
- Clean the gaps: Before applying any filler, make sure to thoroughly clean the gaps using a vacuum cleaner and a damp cloth. This will remove dust, debris, and any loose wood fibers that could interfere with the filler.
- Use a filler knife: Apply the filler with a filler knife or putty knife, pressing the material firmly into the gap. Be sure to smooth out any excess filler and remove any air bubbles from the gap.
- Allow the filler to dry: Once the filler is applied, let it dry completely according to the manufacturer’s instructions. Drying time can vary depending on the type of filler and the environment.
- Sand the filler: Once the filler is dry, sand it smooth using a fine-grit sandpaper. This will create a seamless transition between the filler and the existing wood floor.
- Finish: After sanding, you can stain or paint the filler to match the existing floor if necessary. Be sure to apply a sealant to protect the filler and the surrounding wood from damage.
By following these tips, you can achieve a professional-looking finish that will blend seamlessly with your existing wooden floor. Remember to always consult the manufacturer’s instructions for specific drying times and application methods for the filler you choose.
FAQs About Filling Gaps in Wooden Floors
Here are some of the most frequently asked questions about filling gaps in wooden floors:
Q: Can gaps in wooden floors be prevented?
A: While it’s not always possible to completely prevent gaps from forming in wooden floors, you can minimize their appearance by ensuring proper installation and taking steps to control humidity levels. When possible, acclimate the wood flooring to the environment where it will be installed before laying it down. This helps reduce the potential for expansion and contraction due to changes in humidity. Choose planks that are properly dried and milled, and ensure they are installed with adequate spacing between boards to allow for movement. Maintaining a balanced humidity level within your home can also help prevent your floors from contracting and expanding.
Q: Can I sand down gaps instead of filling them?
A: Sanding gaps can help to make them less noticeable, especially if they are small. However, sanding is not a permanent solution and can even worsen the gaps in some cases. If the gaps are too deep, you can’t sand them away entirely, and sanding too much can damage the wood floor.
Q: How long does the gap filler last?
A: The lifespan of a gap filler depends on the type of filler used and the conditions it is exposed to. Traditional wood filler and wood putty can crack or shrink over time. On the other hand, epoxy-based fillers are generally more durable and last longer. It is also important to note that how well the filler is applied can directly affect its longevity.
Q: Can I fill gaps myself?
A: Yes, filling gaps in wooden floors is a DIY project that many homeowners can tackle with the right tools and preparation, particularly for smaller gaps.
