Gap Filling With Wood Slivers

Large gaps require filling with strips

Properly addressing gaps between floorboards is an essential aspect of maintaining the overall integrity and longevity of your wood floors. These gaps occur naturally as a result of the wood's inherent tendency to expand and contract with changes in temperature and humidity. While these gaps may seem insignificant at first, they can have significant implications for both the visual appeal and functional aspects of your flooring.

From an aesthetic perspective, unfilled gaps can disrupt the seamless look and feel of your wood floors. They create an uneven surface and may accumulate dust and debris over time, detracting from the overall beauty of the space. By effectively filling these gaps, you can restore the floor's visual harmony, providing a more polished and refined appearance.

Exploring Gap Filling Technique

Gap filling offers various methods, but one popular option is utilising wood slivers. While alternatives like filler resin or sawdust mixed with resin exist, we'll focus exclusively on the wood sliver method in this article. Wood slivers can be purchased or created on your own. Other methods such as papier mache, PVA glue, and sawdust are not discussed here.

Why Gap Filling Is Important?

Gap filling is not simply about improving the look of your wooden floor but is also an effective way to deal with draughts. Most of the houses in the UK have air bricks at ground level and allow constant air movement below your floor. Filling the floor gaps will ensure that the warm air will stay in your house during the winter and save you a lot of money on heating bills. In addition to all of this, gap filling will not only increase the overall stability of your wooden floor but also improve its appearance. In the end, gap filling is not just a cosmetic procedure but a welcome and practical solution.Wood strips used for gap filling

The Benefits and Downsides of Strip Filling

Wood slivers are particularly effective for larger gaps, typically around 4-6mm wide. Unlike resin, wood slivers provide a permanent solution, avoiding issues like cracking or detachment. However, it's important to note that slivers may occasionally split. To minimise this, consider using reclaimed wood slivers. Keep in mind that wood sliver gap filling may be slightly more expensive and time-consuming compared to resin filling but offers superior durability.

The Process of Gap Filling With Wood Slivers

To fill gaps between floorboards using wood slivers, follow these steps:

  1. Select appropriate wood slivers: Reclaimed pine slivers are ideal for their suitable properties.

  2. Determine sliver size: Ensure the slivers are slightly larger than the gaps between floorboards and of similar depth.

  3. Apply adhesive: Apply a wood glue of your choice to the sides of the floorboards where the slivers will be inserted.

  4. Insert the slivers: Gently tap the slivers into the gaps using a soft mallet or hammer. Repeat until all gaps are filled.

  5. Allow drying time: Allow the adhesive to dry for approximately an hour, ensuring a secure bond.

  6. Sand the surface: Conduct a fine sanding after the gap filling process to achieve a smooth, level surface.
