When it comes to maintaining or refinishing hardwood floors, gaps between boards can be a common concern. It might seem like a straightforward solution to fill gaps with wood filler, but we generally advise against it.
In this blog post, we will explain why filling gaps with wood filler isn’t recommended and we will explore some better alternatives for handling this issue.
1. Natural Movement of Wood
You may have heard that hardwood floors move over time, and that’s true. Hardwood floors are dynamic and will naturally expand and contract with changes in temperature and humidity. This movement is a normal part of wood’s response to environmental conditions.
When wood filler is used to fill gaps, it doesn’t have the same flexibility as the wood floor itself. And as a result, the wood filler can crack or pop out over time as the boards shift, leaving you with an inconsistent gap and potentially a more problematic issue.
2. Inconsistent Appearance
Wood filler will probably not match the color and grain pattern of your hardwood perfectly. Over time, even if the initial color match is close, the filler and the wood can age and discolor differently. This can result in an inconsistent appearance, with noticeable lines where the filler was applied. Instead of achieving a seamless look, the gaps filled with wood filler can draw more attention to themselves over time.
3. Long-Term Durability
The durability of wood filler is limited compared to the actual hardwood. As mentioned earlier in this post, the movement of the boards can cause the filler to crack and pop out. Additionally, wood filler is generally softer than the hardwood itself, making it more susceptible to wear and tear. This can lead to frequent maintenance and the need for repeated repairs, which can be time-consuming and costly.
4. Alternative Solutions
Instead of using wood filler, we recommend the following alternatives for dealing with gaps between floorboards:
- Seasonal Changes: Understand that small gaps are normal and often close up when humidity levels rise. Sometimes, the best approach is to learn to love it and leave them as they are, especially if they are not causing significant issues.
- Board Replacement: For larger gaps or structural concerns, always consult a floor professional that you trust. They can assess the situation and recommend solutions like replacing individual boards or performing more extensive repairs.
- Wood Strips: In some cases, using matching wood strips to fill large gaps can be a more durable and aesthetically pleasing solution. This method involves cutting thin strips of wood and gluing them into the gaps, then sanding and finishing them to match the surrounding floor.
While it may be tempting to use wood filler to address gaps between boards, it’s not a long-term solution. The natural movement of wood, inconsistent appearance, and potential for damage make it a less-than-ideal choice. Instead, consider the alternatives and consult with professionals to find the best approach for maintaining the beauty and integrity of your hardwood floors.
