What to Use to Fill Cracks in Wood Floors
How do you fill cracks in hardwood floors? Before starting any repair, it’s important to choose a filler that matches the size of the crack, the wood species, and the type of finish used in your home.
Most homeowners pick from these three main options:
- Latex wood filler. This flexible option expands and contracts with your hardwood, reducing the chance of future cracking. Latex is easy to sand, takes stain well, and is water-resistant for added durability.
- Water-based wood filler. This filler dries quickly, cleans up easily, and is non-toxic, making it a convenient and safe choice for indoor projects.
- Solvent-based wood filler. Known for its strong adhesion, this option works best for deep gaps or larger repairs. It won’t shrink over time, but it does require good ventilation due to stronger fumes.
Several factors help determine which product is right for your project, including stain compatibility, durability, and difficulty of application. While latex and water-based fillers suit many DIY repairs, solvent-based options may be best handled by a pro.
5 Steps for Filling Gaps or Cracks in Wood Flooring
With the right materials, filling cracks in hardwood floors is often simpler than homeowners expect.
Follow these steps for a smooth, professional-looking repair:
- Prepare the area. Remove nearby furniture, clean the repair surface, and protect surrounding boards to keep filler where it belongs.
- Apply the filler. Use a small putty knife to press the filler firmly into the crack. The patch should be smooth and level with the floor.
- Allow proper drying time. Most fillers need at least 6 hours to set, but overnight drying is ideal to ensure a fully cured repair.
- Sand the repair. Once dry, carefully sand the spot until it blends seamlessly with the surrounding wood. Apply stain if needed to achieve a consistent finish.
- Seal with a protective finish. A topcoat shields your repair from moisture, dirt, and everyday wear while restoring the appearance of your hardwoods.
Before starting your project, remember that proper prep is essential for successfully filling gaps in wood flooring. Taking time to clean, level, and protect the area ensures the repair integrates cleanly with the rest of the surface.
