How to Fill Gaps in Wood Floors?
Gaps in wood floors can detract from their appearance and lead to issues like drafts, uneven surfaces, and dirt accumulation. Whether you’re dealing with gaps caused by seasonal humidity changes or the natural aging of antique wood floors, addressing them is essential for both aesthetic and practical reasons. At FloorOx.co.uk, we specialize in wood floor restoration and repair, including professional wood floor gap filling services that ensure a seamless and polished finish. Here’s everything you need to know about filling gaps in wood floors.
Understanding Wood Floor Gaps
Before diving into repairs, it’s important to understand why gaps occur in wood floors.
Common Causes of Floor Gaps:
- Seasonal Humidity Changes: Wood expands and contracts with fluctuations in relative humidity levels, causing gaps during drier months.
- Improper Installation: Incorrect installation or failure to account for expansion and contraction can result in gaps.
- House Settling: Over time, structural shifts can create spaces between floorboards.
- Moisture Changes: Excessive moisture or lack of a damp-proofing barrier can lead to wood shrinking or warping.
- Foot Traffic and Wear: High foot traffic and wear can loosen boards over time.
Identifying the root cause of the gaps is crucial before attempting repairs.
Choosing Filling Methods
The appropriate method for filling gaps in old wood floors depends on the size of the gaps, the type of flooring, and the desired finish.
Factors to Consider:
- Gap Size: Smaller gaps can be filled with wood putty or resin and sawdust mixtures, while larger gaps may require wood strips (slivers) or solid wood fillet strips.
- Floor Type: Parquet floors or tongue-and-groove boards may require different approaches compared to traditional planks.
- Seasonal Movement: Flexible solutions, such as acrylic caulks, are ideal for floors prone to seasonal expansion and contraction.
Types of Fillers
Different fillers are suited for different scenarios. Here’s an overview of the most common options:
1. Wood Putty
- Ideal for small gaps.
- Available in various colors for a custom color match.
- Best for gaps that won’t experience seasonal movement.
2. Resin and Sawdust Mixture
- Made by combining floor sanding dust with a clear or colored resin.
- Creates a durable and natural-looking fill.
- Works well for medium gaps and seamless blending.
3. Wood Strips (Slivers)
- Thin solid wood fillet strips cut to size and glued into the gaps.
- Suitable for large gaps.
- Provides a more permanent solution and complements the surrounding wood.
4. Flexible Fillers
- Acrylic caulks or solvent-based fillers that allow for movement.
- Ideal for gaps caused by seasonal humidity changes.
Preparation and Materials
Proper preparation is key to achieving a professional result when filling wood floor gaps.
Materials You’ll Need:
- Wood filler or selected gap-filling material.
- 80 grit sandpaper and coarse sandpaper.
- Dust mask and safety gear.
- Floor sanding dust for resin mixtures.
- Clear varnish or sealant for finishing.
- Tools like a table saw, miter saw, or handsaw for cutting slivers.
Preparation Steps:
- Clean the Floor: Remove dirt and debris from the gaps using a vacuum or soft brush.
- Sand the Area: Lightly sand the edges of the gaps to ensure proper adhesion.
- Gather Matching Materials: Use matching hardwood or wood dust for a seamless finish.
- Ventilate the Area: Ensure proper ventilation if working with solvent-based fillers.
Methods for Filling Gaps
Wood Putty Application

Wood Strip Method
- Cut Strips: Use a miter saw or table saw to cut strips of matching wood.
- Glue the Strips: Apply PVA glue to the edges and press the strips into the gaps.
- Sand and Seal: Once dry, sand the strips flush with the floor and apply a finish.
Flexible Filler Application
- Apply Filler: Use a caulking gun to fill gaps with acrylic caulk.

Maintenance and Prevention
After filling gaps, maintaining your wood floor is essential to prevent future issues.
Maintenance Tips:
- Control Humidity: Use a humidifier or dehumidifier to maintain stable relative humidity levels.
- Seal the Floor: Apply a protective sealant to minimize moisture absorption.
- Regular Cleaning: Sweep and vacuum frequently to prevent debris from accumulating in gaps.
Prevention Strategies:
