Restoring Wooden Floors: Using Resin Mix & Reclaimed Pine Slivers for Gap Filling

Wooden floors carry with them a character, a personality that often resonates with the memories and feelings we associate with a place. Over time, however, the wear and tear exposes gaps and irregularities. These aren’t just cosmetic problems—they can affect the floor’s longevity and safety. The good news? There are sustainable and effective ways to mend these gaps, restoring not just the floor’s beauty but its soul. This article dives into the nuances of gap filling, especially using a resin mix and reclaimed pine slivers.

1. Understanding the Gaps in Wooden Floors

Before diving into the solutions, it’s essential to understand the reasons behind these gaps.

  • Seasonal Movement: Wood is a natural material, meaning it expands and contracts with changes in humidity and temperature. This movement can cause gaps, especially between floorboards.
  • Ageing: As time passes, wooden boards can shrink, leaving gaps that weren’t there before.
  • Damage: High heels, dropping heavy objects, or moving furniture can dent and damage the wood, leading to more gaps.

2. Why gap filling is essential

  • Aesthetics: Obviously, gaps can disrupt the beauty of your floors. A smooth, seamless floor always looks better than one filled with gaps.
  • Safety: Gaps can be tripping hazards, especially for children or the elderly. They can also become dirt traps, hiding places for pests, or areas where moisture can collect and lead to mould.
  • Longevity: Filling gaps can protect the edges of your wooden planks or tiles, preventing them from chipping or wearing down prematurely.

3. Gap Filling with Resin Mix

Resin, especially when combined with wood dust, can be a game changer for mending gaps in your wooden floors.


  • Durable: Resin mix can withstand heavy foot traffic and doesn’t wear out easily.
  • Versatile: It can be coloured to match the floor, ensuring the fill isn’t noticeable.
  • Easy to Use: Resin mix is easy to apply and doesn’t require specialised equipment.


  1. Clean the gap to ensure no dirt or debris is present.
  2. Mix the resin with wood dust to match the colour of your floor.
  3. Carefully apply the mix into the gap using a spatula or filler knife.
  4. Allow it to dry completely.
  5. Sand the area to make it smooth and level with the rest of the floor.

4. Mending with Reclaimed Pine Slivers

Another eco-friendly and effective way to fill gaps is by using reclaimed pine slivers.


  • Sustainable: Using reclaimed pine slivers means you’re recycling wood, reducing the need for fresh timber.
  • Seamless Integration: As the slivers are made from wood, they blend naturally with the rest of the floor.
  • Strength: Pine slivers can provide additional strength to the floor, ensuring the gaps remain sealed for a long time.


  1. Measure the size of the gap to determine the size of the sliver you’ll need.
  2. Choose a reclaimed pine sliver that fits the gap and matches the wood type and colour.
  3. Apply a suitable wood adhesive to the gap.
  4. Gently tap the pine sliver into place using a mallet.
  5. Once the adhesive is dry, sand down the sliver to make sure it’s flush with the floor.

5. Maintenance After Gap Filling

Once the gaps are filled, it’s crucial to maintain the floor to ensure longevity.

  • Regular Cleaning: Dust and mop regularly to prevent dirt from accumulating.
  • Protection: Use rugs or mats in high-traffic areas to prevent wear.
  • Regular Inspections: Check your floors regularly for any new gaps or issues.
  • Refinishing: Over time, consider refinishing the entire floor to ensure its beauty remains intact.

6. Embracing the Soul of Your Floors

While gaps can be a nuisance, the act of mending them can be a labour of love. Each gap tells a story, and by filling them with sustainable materials like resin mix and reclaimed pine slivers, you’re adding new chapters to the history of your home. By investing time and effort into restoring your wooden floors, you’re not just ensuring a beautiful surface to walk on—you’re preserving memories, enhancing safety, and promoting sustainability.

Wooden floors have a soul, a character that has been built over years of memories and footfalls. With the right techniques, you can ensure that this character shines brightly for many more years to come.

7. Alternatives to Consider

While resin mix and reclaimed pine slivers are excellent solutions, they aren’t the only options available. Here are some alternatives to consider:

  • Wood Strips: Thin strips of wood, similar to pine slivers, can be used to fill gaps. These are especially handy for larger gaps and can be glued into place.
  • Papier Mâché Method: A mixture of torn paper and PVA glue can be an economical way to fill small gaps. Though not as durable as other methods, it can be a temporary solution in some settings.
  • Flexible Fillers: These are silicone-based fillers that are particularly useful in areas where there’s a lot of movement, such as near doors.

8. Preventing Gaps in the First Place

Prevention, as they say, is better than cure. To prevent gaps from appearing:

  • Proper Installation: Ensure that the wooden floor is installed correctly. This includes allowing for proper expansion gaps and ensuring that the subfloor is dry.
  • Humidity Control: Invest in a dehumidifier or an air conditioner to maintain the ideal humidity levels in your home, preventing excessive wood contraction or expansion.
  • Regular Maintenance: Oiling or varnishing the floors regularly can prevent excessive moisture absorption and keep the wood in optimal condition.

9. The Art and Heart of Restoration

Restoring an old wooden floor is not just a practical endeavour; it’s also an art. The wood has witnessed many memories, with every grain and groove telling a tale. When you embark on the restoration journey, you’re not only preserving the floor’s physical integrity but also its historical and emotional significance.

This is particularly true when using reclaimed materials. There’s something profoundly poetic about mending an old floor with pieces of another. It’s a merging of histories, a confluence of stories, ensuring that the legacy of both lives on.


Mending the gaps in a wooden floor can be a fulfilling project. Whether you choose a resin mix, reclaimed pine slivers, or any other method, the essence lies in respecting the wood’s history and ensuring its future. With the right approach, you can enjoy the warm embrace of your wooden floor for many more decades, cherishing the memories it holds and the new ones it will undoubtedly witness.
